This is common in fluorometer (radiometric) applications, clinical diagnostics and flow cytometry. The excitation light path is perpendicular to the detection path. Excitation light only enters the detection path through scatter in the sample.

WebCassegrain optical geometry can be used to produce a concentrator system with very compact geometry, with a wide acceptance angle and good efficiency (Fig. 10.13 ). In this design, a converging primary mirror entrains light on a diverging secondary, which in turn focuses on the entrance to an NIO final stage concentrator.
