TFPN: Thin-film Plate Polarizers 45deg
TFPN: Thin-film Plate Polarizers 45deg
Convenient, high power 90° separation of s- and p-polarization at Nd:YAG wavelengths; no angle tuning required. These high performance polarizing cube beamsplitters offer ultrahigh transmission of p-polarized light with 1000:1 extinction ratio at 45° AOI using IBS coatings; no angle tuning required. They are available from stock for high power use at 532 and 1064 nm. Other wavelengths available upon request.
