TFP: Thin-film Plate Polarizers 56deg
TFP: Thin-film Plate Polarizers 56deg
High power separation of s- and p-polarization at Nd:YAG wavelengths; angle tuning required. Designed to operate at the Brewster angle, these economical polarizing cube beamsplitters offer high transmission of p-polarized light with good extinction ratio. Some angle tuning is required to optimize transmission. They are available from stock for high power use at Nd:YAG and Nd:YLF wavelengths. Other wavelengths available upon request.
