Protective lens
Protective focusing lens: it blocks spatter from splashing onto the lens and causing damage to it, and ensures the machining precision requirements by regularly replacing the protective lens. After coating the substrate with a 1064 anti-reflection coating with a high damage threshold (>15Jcm2), the transmittance of the lens can be effectively increased, energy loss reduced, and the quality of the processed product improved.

Mt-optics
Diameter Tolerance: +0.0/-0.2 mm Thickness Tolerance: ±0.2 mm Clear Aperture: >90 %
Brewster angle windows are uncoated substrates used in Brewster angle optical systems. They are used to separate S-polarized light and P-polarized light. When placed at the Brewster angle, the P-polarized light component will pass through the window 100%, while the S-polarized light component will be reflected 20%. MT-Optics provides Brewster windows made of BK7 and UV fused silica.
