conference on Novel optical systems design and Optimization XIV

作者： Garg, Amit Dhingra, Vishal Sharma, Reena Mittal, Ankit Tiwadi, Raman Chakravarty, Pratik Univ Delhi Dept Elect Acharya Narendra Dev Coll New Delhi 110019 India

ISBN: (纸本)9780819487391

Students at the school level from grade 7 to 12 are taught various concepts of geometrical optics but with little hands-on activities. Light propagation through different media, image formation using lenses and mirrors under different conditions and application of basic principles to characterization of lenses, mirrors and other instruments has been a subject which although fascinates students but due to lack of suitable demonstrating setups, students find difficulty in understanding these concepts and hence unable to appreciate the importance of such concepts in various useful scientific apparatus, day to day life, instruments and devices. Therefore, students tend to cram various concepts related to geometrical optics instead of understanding them. As part of the extension activity in the University Grants Commission major research project "Investigating science hands-on to promote innovation and research at undergraduate level" and University of Delhi at Acharya Narendra Dev College spie student chapter, students working under this optics outreach programme have demonstrated various experiments on geometrical optics using a five beam laser ray box and various optical components like different types of mirrors, lenses, prisms, optical fibers etc. The various hands-on activities includes demonstrations on laws of reflection, image formation using plane, concave and convex mirrors, mirror formula, total internal reflection, light propagation in an optical fiber, laws of refraction, image formation using concave and convex lenses and combination of these lenses, lens formula, light propagation through prisms, dispersion in prism, defects in eye-Myopia and hypermetropia. Subjects have been evaluated through pre and post tests in order to measure the improvement in their level of understanding.

MORFEO (formerly known as MAORY) is an adaptive optics module able to compensate the wavefront disturbances affective the scientific observation. It will be installed on the straight-through port of the telescope Nasmyth platform to serve the first-light instrument MICADO and with the provision for a future second instrument. The module underwent the Preliminary design Review in 2021 and is expected to be commissioned in 2029. In this paper we present the current status of the Thermal Control System (ThCS) including the modifications required during the Preliminary design Review. Due to the peculiar optical and mechanical design, a number of FEM and CFD analysis have been performed to verify the compliance of the system to the technical budget. The results of those analysis are then showed together with the current thermal and cooling circuits design derived from them.

conference on design, Fabrication, and Applications of Precision Plastic optics

作者： Meyers, MM Bietry, JR EASTMAN KODAK CO ENGN RES CTRROCHESTERNY 14653

ISBN: (纸本)0819419648

Diffractive optics allow for increased optical performance, decreased size and weight, and decreased systems costs in numerous applications. Many types of optics can be fabricated using diffractive surfaces which are not possible, or not cost competitive, using standard refractive lenses. Diffractive optics technology has been developed at Kodak to the point where low cost, mass produced, plastic-molded diffractive optics are available on a commercial basis. Rotationally symmetric, aspheric, refractive/diffractive hybrid lenses have been injection molded in 100,000 part test runs and the lenses demonstrated consistent quality throughout the test. In this paper we will discuss design, analysis, and fabrication of diffractive optics for some typical applications. These applications include diffractive hybrid achromats for visual applications, such as fixed focus and zoom camera lenses, achromatized laser diode objectives, asymmetric anamorphic concentrating and spectral filtering lenses for rangefinding and autofocus applications, the use of diffractive optics in high quality, grayscale laser writers as beam deflectors and F(theta) lenses. Kodak's diamond turning capability for fabricating diffractive optics and our capacity for fabricating plastic injection mold tooling utilizing diamond turning is discussed. Finally, a discussion of our meteorology technology for examining diffractive surfaces will be discussed.

conference on Advanced optics for Defense Applications - UV through LWIR II

Recently, optical materials have been developed by Schott and NRL to improve material selection in the SWIR, MWIR, and LWIR wavelength regions. In addition, new multiband detectors are reaching maturity, leading to a natural push for common aperture lens systems. Detectors that can span the SWIR/MWIR, MWIR/LWIR or SWIR/MWIR/LWIR wavelengths regions will require complex optical systems to effectively utilize their full potential. designing common aperture wide-band systems that are both achromatized and passively athermal, especially while maintaining SWAP-c (size, weight, power and cost), poses significant challenges. Through use of the updated gamma v-v diagram, which provides guidance on material combinations that both achromatize and athermalize, part of that challenge is reduced. This updated gamma v-v diagram uses instantaneous Abbe number and peak wavelength. The instantaneous Abbe number is a function of wavelength and is the scaled reciprocal of the instantaneous dispersion. The instantaneous Abbe number is defined at the peak wavelength, which occurs when the second derivative of the index of refraction goes to zero. Three examples will be presented using this updated athermal/achromatic glass map to demonstrate its effectiveness. These design examples will include a SWIR/MWIR design, a MWIR/LWIR design and, a SWIR/MWIR/LWIR design.

Development of laser systems requires optical components with high performance, and a high-precision double-beam laser photometer was designed and established to measure the optical performance at 1064nm. Double beam design and lock-in technique was applied to decrease the impact of light energy instability and electric noise. Pairs of samples were placed symmetrically to eliminate beam displacement, and laser scattering imaging technique was applied to determine the influence of surface defect on the optical performance. Based on the above techniques, transmittance and reflection of pairs of optics were obtained, and the measurement precision was improved to 0.06%. Different types of optical loss, such as total loss, volume loss, residual reflection and surface scattering loss, were obtained from the transmittance and reflection measurement of samples with different thickness. Comparison of optical performance of the test points with and without surface defects, the influence of surface defects on optical performance was determined. The optical performance of Nd-glass at 1064nm were measured as an example. Different types of optical loss and the influence of surface defects on the optical loss was determined.

Laser beam shaping systems converting Gaussian to flattop or other irradiance profiles are used in various solar cell manufacturing laser technologies to enhance their performance. Scanning over whole working field with using popular 2- and 3-axis galvo mirror scanners is very often important part of microprocessing systems. Therefore, combining of beam shaping optics with scanning heads is an important technical task in field of solar cells manufacturing. As the beam shaping optics it is suggested to apply field mapping refractive beam shapers. Shaper having some important features: low output divergence, high transmittance, extended depth of field, capability to work with TEM00 and multimode lasers, as result providing a freedom in building various optical systems. De-magnifying of flattop laser beam can be realized with using imaging technique;the imaging optical system to be composed from F-Theta lens of scanning head and additional collimating system to be used right after a. Shaper. One of the problems in this approach is implementation of compact design of the collimating part. As a solution it is suggested to apply a specially designed Beam Shaping Unit being based on. Shaper and locating between a laser and a scanning head;the functions of that combined system are: conversion from Gaussian to flattop laser beam irradiance profile, compact collimator design, alignment features, easy adaptation to a laser and a scanning head used in particular equipment. There will be considered design features of refractive beam shapers. Shaper and Beam Shaping Unit, examples of optical layouts to generate flattop laser spots, which sizes span from several tens of microns to millimetres. Examples of real implementations and results of material processing will be presented as well.

6th Biannual conference on Nonimaging optics: Maximum Efficiency Light Transfer

作者： Chaves, J Collares-Pereira, M Univ Tecn Lisboa Dept Phys Inst Super Tecn P-1096 Lisbon Portugal

ISBN: (纸本)0819441600

A new application of design techniques for nonimaging concentrators is presented. VAriable Geometry Nonimaging optics Devices (VAGNOD) are presented for 2D systems. These devices have a variable acceptance angle allowing for its continuous variation within a range of values. The relation between the sizes of entrance and exit apertures must then vary according to the laws of nonimaging optics. This implies a variation in the size of either the entrance or the exit aperture, resulting in two types of devices. Movable mirrors are an integral part of the new devices discussed in this paper, with positions depending on the variable acceptance angle. These new combinations of optical and mechanical solutions, although not ideal, may represent a practical approximation to ideality.

The MCAO Assisted Visible Imager and Spectrograph (MAVIS) is a new visible instrument for ESO Very Large Telescope (VLT). Its Adaptive optics Module (AOM) must provide extreme adaptive optics correction level at low galactic latitude and high sky coverage at the galactic pole on the FoV of 30arcsec of its 4k x 4k optical imager and on its monolithic Integral Field Unit, thanks to 3 deformable mirrors (DM), 8 Laser Guide Stars (LGS), up to 3 Natural Guide Stars (NGS) and 11 Wave Front Sensors (WFS). A careful performance estimation is required to drive the design of this module and to assess the fulfillment of the system and subsystems requirements. Here we present the work done on this topic during the last year: we updated the system parameters to account for the phase B design and for more realistic conditions, and we produced a set of results from analytical and end-to-end simulations that should give a as complete as possible view on the performance of the system.

Before the transport of a large telescope to site, it is suitable to perform factory tests to guarantee the optimum optical performances. AMOS SA has been awarded the contract from the design to on-site installation of the 2.5-m Class Telescope for Physical Research Laboratory. The 20-m-focal-length telescope has a Ritchey-Chretien optical configuration and provides at Cassegrain location one axial port and two side ports. It is equipped with a primary active mirror and a first order adaptive optical system. It operates in the 0.37-4 mu m spectral range. The project fulfillment relies on the AMOS multidisciplinary expertise in design and manufacturing of high-accuracy optical, mechanical and opto-mechanical systems. This paper presents the test results carried out at AMOS factory to assess the telescope performances (e.g. active optics control loop, pointing, tracking). It relies on extensive tests on the mount control, and the optical and mechanical subsystems before assembly.
