Harmonic Separator 25.4mm Diameter Wavelength 266nm

YHSQ-25.4C05-266

Used to separate or combine YAG (1064nm) and harmonic-converted laser beams (266nm, 355nm, 532nm) by wavelength. Five types with different reflectance wavelengths are available.
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.
