Recent advances in the manufacturing of large (up to 62 mm diameter) glass blanks with axial index gradients of up to 0.20 enable significant performance gains in opticaldesigns. The new axial gradient material has an index and dispersion similar to SF (short flint) glasses, except the index varies continuously through the axis of the blank. The axial gradient material and numerous design examples using the new material will be presented.

An optical minimum configuration of a laser interferometer for noncooperative scattering objects is investigated. An optimization of the SNR (signal-to-noise ratio) of the homodyne receiver is achieved by beam design. Scattering measurement object surfaces generate a speckle pattern on the detector surface which influences the SNR. Within the whole operating range of the optics, the transmitted light spot on the surface under investigation should therefore be small. The receiving optics should image the light spot onto the detector surface. The detection of a noncooperative object in a distance of 26 m is proven experimentally.

Using the concept of matrix theory for lens design, a triplet lens can be replaced by a singlet lens which has an equivalent system matrix without changing its optical performance. Then, using third order Siedel's first aberration coefficient of the singlet lens is equal to zero, and the focal length and the physical length of the triplet lens are kept constant as constraints, an algebraic technique for optimizing a triplet lens is derived. Results show that this new optimizing technique is more effective than other conventional techniques for optimizing a triplet lens in the case of plane waves.

Binary optics is an emerging technology whereby light is directed, combined, or distributed by an optical material having a "stepped" phase structure. We produce computer-generated diffractive elements having high optical efficiency using multiple mask lithography. Perkin-Elmer has an active research and development program supporting binary optics activities from software development to practical technology demonstrations. Standard software tools have been developed to facilitate the design of binary optics from general optical prescriptions. These tools are used to design binary masks for the fabrication of binary optics for diverse applications ranging from simple lenses to general phase transformations. This paper briefly reviews the development of binary optics, discusses the tools supporting the design and fabrication of binary optics, and presents recent applications and demonstrations of binary optics.

The optical system of an optical rotary encoder is presented. The requirements of the optics system are given and their effects on opticaldesign decisions are discussed, Steps taken to insure stable operation over a -40 degrees C to +85 degrees C temperature range are presented. designing for manufacturing toleraces is discussed. A novel application of a fiber illuminator LED as a short-distance collimated source is shown to be an acceptable low-cost alternative to a laser diode. The importance of effective plastic element employment in low-cost, mass-production optical systems is demonstrated.

Hybrid optics offer a valuable aberration correction tool for the lens designer. However, careful consideration must be given to the calculation of the optical performance during the design process, and to the practical implementation of the elements if the potential benefits are to be realised in practice. optical performance can be accurately assessed by tracing multiple diffraction orders. It may be particularly important to utilise such a technique if, for example, the image-forming bundles sample a small number of diffractive zones. This situation is examined in detail.

A number of optical plastic materials are examined. The indices of refraction are measured in the visible and near-infrared spectral regions from 435.8 nm to 1052 mn. Some obtained data and Abbe constants are presented. The glass libraries of the opticaldesign software packages are updated. The spherochromatic aberration balancing is analyzed during the all-plastic doublet and tripler synthesis for a working wavelengths interval from 600 nm to 900 nm. Two achromatic triplets are designed intended for NIR region. Three all-plastic 3X magnifiers are developed for NV goggles. The optical configurations are given. The aberration corrections are evaluated. The obtained optical performance is illustrated. Some conclusions for the trends in all-plastic opticaldesign are drawn.
In this paper, the optical layout, the application, and the working principle of a large-aperture and long-range moiré interferometer (MI) for the quantitative measurement of flow properties are introduced. The i...
