Filter, Extended Hot Mirror, 50.8x50.8mm Square 0/45 degree AOI

Sku: 640-0103

Quick Overview

Extended Hot Mirrors are designed to reduce the heat in an optical system without sacrificing the system’s visible output. While typical hot mirrors reflect from 750nm to approximately 1250nm, Extended Hot Mirrors further reduce heat by extending the reflection range to approximately 1750nm. A multi-layer dielectric coating transmits 85% of visible light while reflecting over 95% of the NIR and IR, making them ideal for projection systems where heat build-up can lead to system damage.
