>> Multichannel Dichroic Prism
THREE CHANNEL NIR PRISM - P/N 9934
General Description
This NIR prism, designed for matrix and linear sensors camera applications, is well-suited to fast lenses imaging onto three high resolution InGaAs sensors (512x1 and 380x240 pixels).
The neutral split 33% over the spectrum range as been optimised and insertible filters can be fitted to the prism faces to further define wavelength outputs.

Outline Dimensions... & Technical Notes
Design and dielectric film combine to minimize polarization effects and shifts in the angle of incidence to assure a cone angle of ± 10°. Each channel transmits at more than 30%.
Special glass has been used to optimize the transmission value of the final system, including the antireflection coating with an efficiency better than 99%.
