A method is proposed to build and design modularize system to implement solar illumination system. Using Oliker-like freeform reflector to achieve uniform and precisely illumination distribution.
We proposed a method to automatically eliminate the obscuration in the design of off-axis mirror systems without plane of symmetry. Off-axis settings and local surface expression are designed to simplify the system representation. Obscuration error function is established based on the positional relation between the proposed mirror boxes and ray boxes, and through function optimization, the obscuration is eliminated. The method is demonstrated by two examples, indicating its ability to eliminate obscuration for totally off-axis mirror system and the searching for such systems from co-axial starting points.

An all-spherical catadioptric telescope with an aperture of 75 cm and an angular field of view with a diameter of 10◦ (260 mm) is described. The design provides D80 image quality better than 1.9′′ (13.6 μm) on a flat detector. The limiting stellar magnitude and speed of the sky survey achievable with this system are estimated.

At the 2017 IODC, David Shafer gave a paper [1], and showed how a catadioptric design form could be improved by evolving from some elements being used in single pass to them being used double pass. He observed that this evolution couldn’t occur with a design program’s optimizer because the sequential modeling paradigm doesn’t support this without additional input from the user. The designer, on the other hand, can see the possibility of moving elements to jump to a new solution space. This comment was a catalyst for reexamining how sequential optical modeling developed. The goal is to address the modeling issue identified by Shafer without sacrificing the simplicity of sequential model specification. In other words, can an image forming modeling system be built that: • Retains the optimum performance and convenience of sequential models • While providing greater support for the designer’s view of the actual optical system. To assess the feasibility of these ideas, the software package ray-optics was developed using the Python language. Python is very advantageous for prototyping scientific software because of its broad ecosystem of open-source math and science software packages.

The lens design problem for the 2021 IODC is to design a 100 mm focal length lens where if the lens is flipped end-to-end but the radii are not reversed in sign, the lens has to perform the same as in its original form. The lens is used monochromatically. The goal of the problem is to maximize the product of the entrance pupil diameter and the semi-field of view while holding the RMS wavefront error to ≤ 0.070 wave within the field of view. There were 43 entries from 13 different countries. Three different commercial lens design programs were used, along with four in-house programs. The winning entry from Damien Gawron has an entrance pupil diameter of 198.4083 mm and a semi-field of view of 90° for a merit function product of 17,857 out of a maximum possible 18,000.
