This filter is NOS from an instrument manufacturer. The filter separates a band of Deep Red by reflecting it at right angles to the incidence light, while transmitting nearly all of the Blue Green and Red. (A secondary band of Blue is reflected).
The filter makes a very good beam separator of two emission signals.
filter specifications follow: Reflection band 470 to 630 with average of 98%, Transmission band 660 to 1000+ nm with an average of >90%, Size 26X36mm mm, Substate material is fused silica. Original cost $150
