Optically Contacted Zero Order Λ/4 Quarter Wave Plate, Optical Path Glue-Free

Overview:

Optically contacted zero order waveplate is made from two multiple order plates with slightly different thicknesses. The two plates are constructed by optically contacted method and this design allows the optically contacted zero order waveplate to operate well in relatively high power application and wide wavelength range. The slow axis of one waveplate is aligned with the fast axis of the other waveplate. The difference in thickness is selected to obtain the required net phase change.

Optically contacted zero order waveplates also feature particularly fine wavefront distortion and parallelism as the optical path is glue-free.

Main Features of Optically Contacted Zero Order Wave Plate:

Optically contacted, glue-free structure
Wide operational wavelength range and high temperature-stability
High damage threshold and excellent wavefront distortion and parallelism
Better retardation steadiness
