  • Since a dielectric multilayer coating is used, there is no absorption in the coating and it can be used for laser beams with high energy density.
  • Can be used for lasers with large beam diameters because of the plate type.
  • The high reflectivity of 99.2% or more (98% or more for dual wavelength specifications) enables separation of reflected wavelengths from transmitted wavelengths.

Attention

▶Due to the effect of the refractive index and thickness of the substrate, the light path of transmitted light shifts several mm parallel to the incident light.

▶Transmittance and reflectance wavelength characteristics change when used at incident angles other than 45 degrees.

▶Use the side indicated by the arrow on the side of the substrates as the reflective side. Reflection on the back side may cause loss of light intensity and ghosting.

▶Transmitted light is rarely mixed with light of reflected wavelengths, but reflected light may be mixed with light of transmitted wavelengths. (5% to 15%)

▶The wavelength characteristic of transmittance varies depending on the polarization orientation of the laser.
The specifications show average values for P and S polarization.
Please check the actual laser polarization orientation before use.
