Chromium Cube Half Mirror 10mm 750 - 850nm
CSCH-10-800
Chromium cube half mirrors consist of two right angle prisms. One of them is coated with chromium (Cr) on the hypotenuse face. Half mirror divides input beam to reflectance and transmittance in 1:1. A beamsplitter of R:T=1:1 is called “Half Mirror”.
◦Four surfaces of the cube are coated with multi-layer anti-reflection coatings.
◦Approximately one third of the input beam is lost because of absorption of chromium coating on the hypotenuse. However these beamsplitters are not wavelength, polarization and incident angle of the input beam dependent and therefore provide a highly neutral reflectivity.
◦For cube beamsplitters, unlike plate beamsplitters, transmission beam deviations and ghosts rarely occur.
