Brewster Prism from Japan
A prism cut at Brewster's angle to minimize reflection losses when used at specific polarization for laser cavities. Classified under HTS 9001.90.50.00 as an unmounted dispersion prism optimized for p-polarized light transmission. Provides both dispersion and polarization selection in tunable lasers.

Import Tips
• Specify Brewster angle precision and material refractive index data
• Polarization extinction ratio testing required for laser applications
• High transmission coating specifications mandatory for cavity use
