Neutral Broadband Cube Beamsplitters

 Neutral Broadband Cube Beamsplitters

Product name : Neutral Broadband Cube Beamsplitters
Description :
● All Metal Coating
● Extreme broadband Single Layer MgF2 coating in all legs
● Absorption = 45% +/- 5%
● Spectral range : 350-2100nm

These all-metal coatings both absorb and reflect the incident radiation. These beamsplitters have high absorption and high neutrality over a range covering the visible and near infra-red. R and T are about 27% with 45% absorption.
