In the article some methods for processing the information contained in a database are offered with the purpose of extraction of the knowledge, the experience and the intuition of the designers, coded in the database. It gives much attention to the methods for determinating limit potential image quality of optical systems of various complexities.

A file sharing site for lensdesigns has been started at *** . This site currently contains almost 2,000 optical models. Many engineering disciplines have built public libraries of useful, publicly-available content. For example, GITHUB(1) has publicly-available software;GrabCAD(2), 3DcontentCentral(3), TurboSquid(4) all offer mechanical engineering content such as solids files;TI, Analog, etc. offer reference designs for electronics engineers. Generally, these services aren't just file repositories;they also offer collaboration, yielding more models, more refinement, more discussion, more community, and more to learn. lensdesigners can also benefit from such design libraries. This paper explains the utility and structure of the site.

In the paper, we present a design of street light with use of a TIR lens and a specific diffuser of micro-lens array. In the illumination area of 39 m x 16.4 m, the power, output flux and the efficiency of the street light on the target area are about 160 W, 10530 lm and 85 %, respectively, and the uniformity reaches 1/1.64.

In order to produce an instrument or sensor design in the face of demanding environmental constraints of a spaceborne system, an integrated approach to sensor design has been developed that incorporates design tools for: opticaldesign, mechanical design, structural, stray light and thermal analysis. This integrated approach can be extended to the entire payload design and its increased constraints.

This paper discusses some methodologies that apply to the opticaldesign of reflective wide-field cameras. Among the methods considered are off-axis and eccentric pupil systems, concatenation of systems, tilted component systems, aberration theory, and confocal systems. The goal of the paper is to review design methods. In particular some systems are shown to illustrate two methodologies.

Dual field of view optical systems provide search, detect and observation abilities with wide and narrow field of views. These systems provide dual field of view by changing the effective focal length with moving a lens or lens group mechanically to exact positions. In this paper, previously proposed methodology is used to change effective focal length without any mechanical movement. This methodology relies on ionization of fluid with voltage difference to change the refractive index which is patented in 2022.
