950nm short wave dichroic filter

The 950nm short wave pass dichroic mirror, beam splitter, combiner or dichroic filter produced by Borisun Optics has a variety of sizes to choose from.

The short wave through dichroic mirror / combiner provided by Borisun Optics divides the beam into transmitted light and reflected light according to the design wavelength. The short wave through dichroic mirror has high transmittance for beams below the cut-off wavelength and high reflectivity for beams above the cut-off wavelength. We also provide a long wave pass dichroic mirror, which has high reflectivity for beams below the cut-off wavelength and high transmittance for beams above the cut-off wavelength.

The short wave through dichroic mirror and combiner we provide have a variety of medium wavelengths to choose from. Moreover, in the corresponding transmission and reflection bands, the absolute transmittance and absolute reflectivity are more than 90% and more than 95% respectively. It is designed for 45 ° incident angle and has circular and square dimensions.

Such an optical element can also be used to combine a beam whose wavelength (or wavelength range) is less than the cut-off wavelength with a beam whose wavelength (or wavelength range) is greater than the cut-off wavelength. Usually they are also used to separate the light superimposed by different color spaces.

One surface of these optical elements is plated with dichroic film and the other surface is plated with antireflective film.
