IBS coat optical element ::::: Polarization-independent beam splitter

Achieves a reflectance difference between S-polarized light and P-polarized light of less than 5% (customizable down to 1%).

Manufacturer: Optoman (Lithuania) Fixed beam splitter cubes often fail in high-power laser applications due to epoxy layers and coatings. Optoman offers a dielectric non-polarizing beam splitter plate that does not depend on the polarization of the incident beam. ◆ S-polarized and P-polarized component matching rate of 5% or less ◆ Achieving reflection and transmission of S-polarized and P-polarized light with a tolerance of 5% or less essentially makes this product polarization-independent. While the typical tolerance is 5%, for even stricter specifications, Optoman can provide a tolerance of less than 1% for S-polarized and P-polarized light. ◆ Back AR coating for ghost removal ◆ The front surface is coated with a multi-layer dielectric coating, while the back surface is also AR coated to minimize reflection loss and eliminate ghosts. With cutting-edge IBS coating technology, we achieve excellent features such as high damage threshold, low absorption, low scattering, and long lifespan. OPTOMAN can propose custom products tailored to your needs.
