Optical filter dichroic 495DCSP 25X36 beamsplitter @45
This filter is NOS from an instrument manufacturer. The filter separates a band of Green and Red, by reflecting it at right angles to the incidence light, while transmitting nearly all of the Blue.
This is a difficult filter to realize. It has many applications such as to resolve emission of a blue and green or red laser, or Fluorescence signature. This Dichroic will do this well in Polarized light.
The filter makes a very good divider of an optical emission signal, into two channels or detectors.
filter specifications follow: Reflection band 530 to 650nm with average of 95+%, Transmission in the band 480 to 365 nm with average of 80% transmission, Size 25.4X36.6 mm, Substate material is Boro Glass. Original cost $250
