Description

This 520 dichroic splitter is designed for 45° incidence: it efficiently reflects blue-green light in 440–520 nm while allowing yellow-green and infrared light in 520–1100 nm to pass at a fixed low transmission of 5–10%. This unique splitting behavior makes it ideal for precision optical systems requiring optical-path monitoring, power sampling or low-intensity illumination: the reflection path carries most of the 440–520 nm energy (R 90–95%), while the low-transmission path feeds a detector for real-time laser power monitoring without disturbing the main beam, and it can also separate signals by wavelength in spectral analysis.
