  TrueSplit™ is a breakthrough in beamsplitter technology. While most non-polarizing beamsplitters require hybrid metallic coatings or cemented interfaces which 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 > 20J/cm2. Furthermore, this can be realized with almost any R/T ratio (not just 50/50) and almost any wavelength.
