Non-Sequential Physical Optics in Telescopes and Offner Systems
Time: 2018-08-02 15:54Source: infocrops.comWriter: infocrops
In our previous newsletter we demonstrated the ghost-image effect caused by the undesired reflection between surfaces in a collimation system. In contrast to that situation, some optical systems are designed to take advantage of the multiple pass between surfaces. We present here two such examples: a Herrig telescope and an Offner system. With the help of the non-sequential field tracing, this kind of systems can be modeled and analyzed easily and fast.

 
Herrig Schiefspiegler Telescope
 
A Herrig Schiefspiegler telescope with two mirrors, but with four reflections in a double-pass configuration, is modeled with the non-sequential ray- and field-tracing techniques in VirtualLab.
 
 
Analysis of an Offner System with Non-Sequential Field Tracing
 
An Offner system that consists of two concentric spherical mirrors is built up and its imaging properties investigated using non-sequential field tracing in VirtualLab.
