Flabeg

Dielectric beam splitters split the incident light into a transmission component and a reflection component. The ratio of transmission and reflection is always complementary and adapted to the customer’s wishes. Beam splitters consist of a sequence of high and low refractive dielectric materials, which are separated in a high vacuum using electron beam evaporation. To reduce interfering secondary reflections and mirror effects, the beam splitter’s output side has a wide-band anti-reflective coating.

Beam splitter plates made by FLABEG are especially resistant to environmental effects, such as humidity, temperature fluctuations, and mechanical stress. A further strength of dielectric layer systems compared with metal splitter mirrors is their very low absorption, which means that the beam of light is divided into a reflection component and a transmission component virtually without loss.
