Product Description

Substrate material: UV fused silica
Application: Filtering, beam splitting and combining

LBTEK Multi-Band Dichroic Mirrors have two transmission bands and one reflection band. These dichroic mirrors have high transmission performance in the band shorter than the cut-off wavelength and longer than the cut-on wavelength, and high reflection performance in the band between the cut-off wavelength and the cut-on wavelength.

Multi-Band Dichroic Mirrors

Substrate Material: UVFS
Size: Ø25.4 mm
Application: Filtering, beam splitting and combining

The LBTEK Multi-Band Dichroic Mirror features two transmission bands and one reflection band. Our multi-band dichroic mirror has a cut-off wavelength of 740nm and a cut-on wavelength of 940nm, with an average transmittance greater than 90% in the wavelength ranges of 480-710 nm and 1000-1700 nm, and an average reflectance greater than 95% in the range of 753-935 nm. One surface of the dichroic mirror is coated with a filter coating, while the other side has an anti-reflective coating, with the arrow pointing to the filter-coated surface.

LBTEK Multi-Band Dichroic Mirrors are often mounted in 30 mm coaxial cube circular flat mount.
