LBTEK-beam sampling mirror

Product Description

Optical material: UV fused silica
Operating wavelength: 245 nm-400 nm, 400 nm-700 nm, 700 nm-1100 nm, 1100 nm-1700 nm
Application: spectral splitting

LBTEK beam sampling mirrors are fabricated using UV fused silica substrates. By coating an anti-reflection film on their wedge surface and allowing incident polarized light to reflect off the uncoated surface, they achieve beam splitting and sampling functions. These beam sampling mirrors utilize the Fresnel reflection from the uncoated optical surface to sample 1-10% of the incident light, depending on the polarization direction of the incident light. When P-polarized light is incident at a 45° angle, the sampling mirror produces approximately 1% reflection, while S-polarized light yields about 10% reflection. Additionally, the back surface is coated with an anti-reflection film to effectively reduce reflections (ghost images). The beam sampling mirrors are designed with a 30' wedge angle to further minimize ghosting and interference effects. Currently, LBTEK beam sampling mirrors are available in multiple operating wavelength ranges and sizes.
