In this paper we present a comparison of the data on aerosol number size distribution measured with GRIMM 1.109 aerosol spectrometer in the lower troposphere over Novosibirsk and background area 150 km south-west of it during research flights of Optik TU-134 aircraft laboratory carried out along the route Novosibirsk - Ordynskoye - Novosibirsk in 2011-2013. Aerosol number size distributions averaged over 3 years as together so for warm and cold seasons separately are considered here. It is shown that the accumulation of anthropogenic aerosol within the BL over the city is typical for the cold period, which is most likely caused by inversions those are rapidly destroyed by vertical mixing during warm season and anthropogenic aerosols from the city are transported into the free troposphere.

Recently we introduced RESCH microscopy [1] - a scanning microscope that allows slightly refocusing the sample after the acquisition has been performed, solely by performing appropriate data post-processing. The microscope features a double-helix phase-engineered emission point spread function in combination with camera-based detection. Based on the principle of transverse resolution enhancement in Image Scanning Microscopy [2,3], we demonstrate similar resolution improvement in RESCH. Furthermore, we outline a pathway for how the collected 3D sample information can be used to construct sharper optical sections. [1] A. Jesacher, M. Ritsch-Marte and R. Piestun, accepted for Optica.

Extensive airborne in-situ measurements of atmospheric trace gas species and aerosols over the Siberian Arctic were carried out in July 2008 in the framework of the YAK-AEROSIB and POLARCAT projects under the International Polar Year (IPY). During the campaign, the Optik-É AN-30 aircraft laboratory was used as a research platform (Antokhin et al., 2012). The measurement campaign consisted of two longitudinal and two latitudinal transects in the troposphere from the ground level to a height of about 7 kilometers. The arctic longitudinal transect extended from 66° 37'23'E to 170° 44'18'E, and the remote continental one - from 129° 46'47'E to 82° 47'25'E. Along the Arctic coast, the sea was ice covered. Measurements showed that variation of CO2 mixing ratio within the lower troposphere (below 3 km) over the Arctic region was small and ranged from 382 to 385 ppm, whereas over the remote continental regions CO2 concentration values were lower and varied over a wider range from 367 to 381 ppm (with minimum over forested areas). So, the conclusion can be drawn that CO2 uptake by Siberian arctic ecosystems is weak. Maximal mixing ratios of CO (≡100 ppb) observed within the lower tropospheric layer over the Arctic were 1.4 times lower than the free tropospheric ones. The vertical ozone distribution obtained during the flights along the Arctic coast showed that ozone was mainly transported from the stratosphere.

Mass Manufacturing Challenges For CPV Primary And Secondary Optics

NASA Astrophysics Data System (ADS)

Luce, Thomas; Cohen, Joel

2010-10-01

Crucial for the performance and longevity of CPV installations is the efficiency of the optics used. Low production cost and high performance are key for the economical success of a CPV concept. To be able to compete with existing energy sources, proven mass production methods as well as high performance materials have to be employed. The injection molding process is the ideal serial production process capable to deliver at the same time high part quantities, excellent part precision and repeatable part quality at low manufacturing cost. Primary and secondary optics require different materials to be applied. The Pros and Cons of these materials in terms of production properties and achievable part precision will be discussed. We will show quality results for primary Fresnel optics using PMMA and, alternatively Silicone on Glass. For secondary optics we will demonstrate the use of optical silicone lenses widely used for high power LED applications today. Optical grade silicone has an excellent environmental stability even when encountering high energy density levels. The experience of Eschenbach Optik in injection molding silicone optics shows that this material is a very cost competitive alternative for glass secondary optics providing both highest optical performance and precision.

The purpose of this project was to develop a method that, while providing morphological quality control, allows single cells to be obtained from the surfaces of various evidence materials and be made available for DNA analysis in cases where only small amounts of cell material are present or where only mixed traces are found. With the SteREO Lumar.V12 stereomicroscope and UV unit from Zeiss, it was possible to detect and assess single epithelial cells on the surfaces of various objects (e.g., glass, plastic, metal). A digitally operated micromanipulator developed by aura optik was used to lift a single cell from the surface of evidence material and to transfer it to a conventional PCR tube or to an AmpliGrid(®) from Advalytix. The actual lifting of the cells was performed with microglobes that acted as carriers. The microglobes were held with microtweezers and were transferred to the DNA analysis receptacles along with the adhering cells. In a next step, the PCR can be carried out in this receptacle without removing the microglobe. Our method allows a single cell to be isolated directly from evidence material and be made available for forensic DNA analysis. © 2010 American Academy of Forensic Sciences.

The results of sensing of the gas and aerosol composition of the atmosphere with the Optik Tu-134 aircraft laboratory in the period from 31 July to 1 August 2012 are presented. The measurements were conducted along the flight route Novosibirsk-Tomsk-Mirny-Yakutsk-Bratsk-Novosibirsk. A significant part of the Siberian territory during this period was covered by numerous forest fires. The synoptic situation during the measurements was characterized by the presence of low-gradient field. This fact determined the low rate of transport and diffusion of pollutants and their accumulation in the region under study. The maximal concentrations of CO2, CH4, and CO over fire zones achieved 432 ppm, 2367 ppb, and 4036 ppb, respectively. The aerosol particle number density in emission plumes achieved 4400 cm-3. Outside emission plumes, the concentration ranged within 400-1000 cm-3 depending on the region. The mass concentration of aerosol in plumes increased approximately 7 times (6.9). The enrichment of the concentration of some elements and ions in the plume with respect to the background varied from 1.3 to 9.1 times. The generation of ozone from biomass burning products was observed at plume boundaries. Two versions of this process are possible: ozone generation under and above the plume.

Introduction: The history of the first operating microscopes from Zeiss is often confusing, not painstaking and partly contradictory because of the parallel development of Zeiss Jena (East Germany) and Zeiss Oberkochen (West Germany). Methods: To investigate the early beginnings of the construction of the operating microscopes documents of the Carl Zeiss Archive and the Optical Museum in Jena, the memoirs of Prof. Dr. Rosemarie Albrecht and some relevant publications were used. Results: The development of the first Jena operating microscope was initiated in 1949 by the ENT-physician Prof. Dr. Rosemarie Albrecht in the Soviet occupation zone. The first prototype was tested in the University ENT Clinic, Jena since summer of 1950. On the Leipzig Trade Fair in autumn 1952 the VEB Optik Carl Zeiss Jena presented the first operating microscope nationally and internationally. Series production began in 1953. The first operating microscope of Zeiss Oberkochen was primarily developed by technical designers (H. Littmann) as a colposcope. But in the Carl Zeiss Archive no documents could be found related to the cooperation with gynecologists. 1953 the operating microscope (OPMI 1) came into public and its series production started. From this date on, it was adopted by the otologist Prof. Dr. Horst Ludwig Wullstein to the needs of Otorhinolaryngology. Conclusion: The first Zeiss operating microscope came from Jena. The operating microscope from Zeiss Oberkochen had some advantages for the surgeons and won the competition in the future. © Georg Thieme Verlag KG Stuttgart · New York.

Der bekannte Astronom Karl Schwarzschild (1873-1916) gilt als der Begründer der Astrophysik und als hervorragender Forscher mit einer erstaunlichen Bandbreite seiner Interessen. Arbeiten zur Himmelsmechanik, Elektrodynamik und Relativitätstheorie weisen ihn als vorzüglichen Mathematiker und Physiker auf der Höhe seiner Zeit aus. Untersuchungen zur Photographischen Photometrie, Optik und Spektroskopie zeigen den versierten Beobachter, der sein Meßinstrumentarium beherrscht, und schließlich arbeitete Schwarzschild als Astrophysiker an Sternatmosphären, Kometen, Struktur und Dynamik von Sternsystemen. Die in seinem kurzen Leben entstandene Fülle an wissenschaftlichen Arbeiten ist in drei Bänden der Gesamtausgabe gesammelt, ergänzt durch biographisches Material, Annotationen von Fachleuten und einen Essay des Nobelpreisträgers S. Chandrasekhar. The well-known astronomer Karl Schwarzschild (1873-1916) is regarded as the founder of astrophysics and as an exceptionally talented researcher whose interests spanned a remarkably broad spectrum. His work on celestial mechanics, electrodynamics, and relativity theory demonstrates his great abilities as a mathematician and physicist who significantly influenced the science of his times. His investigations of photographic photometry, optics, and spectroscopy display his strengths as an observer who knew his instruments. But above all Schwarzschild pursued questions of astrophysics, addressing in particular stellar atmospheres, comets, and the structure and dynamics of stellar systems. The host of scientific works that he authored in his short life is now collected in the form of this three-volume complete works; it is supplemented by biographical material, notes from some of todays experts, and an essay by the Nobel Laureate S.

JENOPTIK Laser, Optik, Systeme GmbH (JO L.O.S.) enlarged its product range in the field of cylinder lenses and crystal optics. These components are used in optical measuring technology and in various laser applications. The new cylinder components are a result of the state of the art manufacturing technology. For applications, where the quality of standard cylinders with a surface deviation of PV Lambda/2 to Lambda/5 @632,8nm and tested with a reference glass only is not sufficient, the surface shape can be improved to PV Lambda/10 @632,8nm. The presentation deals with Jenoptik's current state to produce cylinder optics, to reduce remaining surface shape deviations of semi-finished cylinder optics and to test these elements. Based on in-house developed machinery, cylinders are manufactured by means of blocking or drum. The required surface quality in the range of PV Lambda/10 @632,8nm for cylindrical lenses can be reached by computer aided correction using mrf-polishing techniques in connection with an interferometer test set-up. Therefore, the polishing machine is equipped with an additional axis of movement. The interferometer measurement of the residual surface deviation is done by Computer Generated Holograms (CGH), which are designed and manufactured in-house. CGHs from JO L.O.S. for testing cylindrical lenses can be custom designed starting with F#1.0. They are related to the typical rectangular geometry of cylinder components. Using these measurement techniques, testing is no longer the limiting factor in achieving high quality cylindrical surfaces. JO L.O.S. has all the capabilities of effective manufacturing, testing and correcting cylindrical lenses. Latest results achieved in series production are shown.

The main aim of the work was complex experimental measurements of microphysical, chemical, and optical parameters of aerosol particles in the surface air layer and free atmosphere. From the measurement data, the entire set of aerosol optical parameters was retrieved, required for radiation calculations. Three measurement runs were carried out in 2013 within the experiment: in spring, when the aerosol generation maximum is observed, in summer (July), when the altitude of the atmospheric boundary layer is the highest, and in the late summer - early autumn, when the second nucleation period is recorded. The following instruments were used in the experiment: diffusion aerosol spectrometers (DAS), GRIMM photoelectric counters, angle-scattering nephelometers, aethalometer, SP-9/6 sun photometer, RE 318 Sun-Sky radiometer (AERONET), MS-53 pyrheliometer, MS-802 pyranometer, ASP aureole photometer, SSP scanning photometer, TU-134 Optik flying laboratory, Siberian lidar station, stationary multiwave lidar complex LOZA-M, spectrophotometric complex for measuring total ozone and NO2, multivariable instrument for measuring atmospheric parameters, METEO-2 USM, 2.4 AEHP-2.4m station for satellite data receive. Results of numerical calculations of solar down-fluxes on the Earth's surface were compared with the values measured in clear air in the summer periods in 2010—2012 in a background region of Siberian boreal zone. It was shown that the relative differences between model and experimental values of direct and total radiation do not exceed 1% and 3%, respectively, with accounting for instrumental errors and measurement error of atmospheric parameters. Thus, independent data on optical, meteorological, and microphysical atmospheric parameters allow mutual intercalibration and supplement and, hence, provide for qualitatively new data, which can explain physical nature of processes that form the vertical structure of the aerosol filed.

In this paper we present some results of the analysis of organic compounds contained in the particulate matter sampled in the Siberian air shed during monthly research flights in 2012-2013. Aerosol sampling was performed in the tropospheric layer from 500 to 7000 m over the Karakan pine forest located on the east bank of the Novosibirsk Reservoir (River Ob). The Optik TU-134 aircraft laboratory was used as a research platform for in-situ measurements of atmospheric trace gas species and aerosols, as well as a particulate matter collection on PTFE filters. Analysis of the particulate organic matter sampled in the Siberian air shed in 2012-2013 allowed us to draw the following conclusions: the total content of n-alkanes increases in the spring and decreases in the winter. the length of the n-alkane homologous series had no seasonal dependence. maximum in the molecular weight distribution of n-alkanes varies depending on the season; compounds with C17, C22 and C25 chains dominated in winter and spring 2012, whereas in summer - C17 ones; in 2013 compounds with C17 chains dominated in winter, C18-C20 - in spring, and C21 and C23 - in summer. Carbon preference index (CPI) value for a given chain length of the homologous series (on the average from C12 to C28) did not reflect the contribution of sources of n-alkanes in the atmosphere.
