Fused Silica (UV) Miniature Brewster Window
Brewster windows are high-performance window elements specially designed for laser systems and polarization optics structures. Due to incidence at the Brewster angle, both the reflection and transmission of P-polarized light approach zero, thereby significantly reducing energy loss. With their high damage threshold, low wavefront distortion and excellent thermal stability, Brewster windows are widely used in high-power laser systems, resonant cavities and polarization control modules.
