Dichroic Filter Characterizations

High Energy Physics - Experiment 2025-09-11 v3

Abstract

We present here measurements and characterizations of several dichroic filters, which are being used more commonly in nuclear and particle physics for photon-detection. The measurements were performed on filters immersed in several media: air, water, and LAB-based liquid scintillator. Measurements of transmission and reflection properties were made at various angles of incidence, and the data presented here can be used to develop detailed optical models for detector simulations. We find a modified Bragg's Law is a good model for the shift in transmission edge as a function of angle of incidence, across the various media.
