Offner relay mirrors

WebbAgain, concerns about cost and figure accuracy eliminated these types of systems. 3.2 Offner relay design After some investigation, a traditional Offner relay was chosen as the focus of the design. The biggest advantage is that it uses all spherical surfaces which will allow relatively cost-effective optical elements. Webb15 mars 2024 · I'm trying to test and optimize an optical system that uses off-axis parabolic mirrors under 90° to relay an image. I did manage to get an imaging system with 90° reflection to work and also to produce the correct parabolic shape with conic constant=-1, but the optical axis is always at the pole of the parabola.
