ZnSe Plate Beamsplitters
ZnSe plate beamsplitters split or combine CO2 laser and infrared beams with coating-defined T/R ratios and polarization behavior.
Quick Specifications
Product Description
Overview
ZnSe plate beamsplitters divide an input infrared beam into transmitted and reflected paths, or combine two beams into one optical path. They are typically specified for CO2 laser optics, IR beam sampling, diagnostics, and beam routing where the coating defines the transmission/reflection ratio.
Why Coating and Polarization Matter
At a typical 45° angle of incidence and 10.6 µm wavelength, s- and p-polarization can respond differently. The final specification should define the target T/R ratio, operating wavelength, angle of incidence, polarization condition, beam size, and coating side before release.
Typical Specifications

Engineering Notes
- Confirm whether the optic is used as a beamsplitter, beam sampler, or beam combiner.
- Specify wavelength, angle of incidence, polarization state, and required transmitted/reflected energy balance.
- Share beam diameter, clear aperture, substrate size, coating side, and mechanical mounting limits.
Request Engineering Review
For custom ZnSe beamsplitter coating review, send the wavelength, beam size, angle of incidence, polarization condition, and target T/R ratio through the contact form. You can also compare related ZnSe optics in the product catalog.
