TrueSplit™ is a breakthrough in beamsplitter technology. While most non-polarizing beamsplitters require hybrid metallic coatings or cemented interfaces that absorb energy, TrueSplit™ has only hard dielectric coatings and no bonded interfaces. As a result, it achieves < 3% P-S polarization performance with almost no absorption, and a damage threshold> 20 J/cm2. Furthermore, this can be realized with almost any R/T ratio (not just 50/50) and almost any wavelength.

NOTE:
1. The selection of the substrate material is dependent on the wavelength. Above 450nm, BK7 will be used unless other material is requested.
2. Any other wavelength and R/T ratio can be supplied on request.
3. There could be some "minimum order quantity" even for the standard wavelengths. Please check it with us.4. Please describe your custom requirements in detail when you contact us.
