>> Multichannel Dichroic Prism
FOUR-CHANNEL PRISM - P/N B9804
General Description
This is an RGB-IR prism especially designed for linear camera application, as reported in the layout drawing. The main characteristics of this assembly in the capability to accept a very high F/N, until F/N=2 to guarantee a good energy transmission (very important for the Line Scan Camera acquisition system).
Is also possible, upon request, to provide some trimming filter to define better the output wavelength. In the attached questionnaire, the customer can define properly the specification if different to this standard product.

Outline Dimensions
The solution reported is the best compromise between the performances and dimensions, mainly about the optical path in glass because related to the back focal length of the lenses.
Technical Notes
The angle are also optimised to minimise the polarisation effects. The dielectric film is designed in order to minimise the shifting of the curves (vs the angle of incidence) providing a good results for nominal angle ±10 degrees. Good transmission and coating repeatability are the warranty for the final product performances. More details are available for the customer upon request.
