Product Description
- Optical Material: Borofloat Glass, UVFS
- Silicon Dioxide Protective Layer
- Working Wavelength: 250 nm-600 nm, 250 nm-450 nm
- Application: Optical Path Deflection, Beam Splitting
UV-enhanced aluminum-coated mirrors are highly suitable for beam deflection (O-shaped, elliptical) and beam splitting (D-shaped) across a broad ultraviolet spectrum, offering high reflectivity over a wide spectral range. The reflection of the beam occurs on the metal film surface, eliminating chromatic aberration. However, metal films are prone to oxidation, discoloration, or peeling in high-humidity environments. LBTEK's UV-enhanced aluminum-coated mirrors feature a protective silicon dioxide layer on the surface to isolate the metal film from direct contact with air, preventing oxidation and preserving optical performance. LBTEK offers UV-enhanced aluminum-coated mirrors in various shapes, including circular, elliptical, and D-shaped, among others. All our mirrors undergo precision machining and strict quality control to ensure that LBTEK provides high-quality mirror products at reasonable prices.

LBTEK offers cost-effective UV-enhanced aluminum-coated flat mirrors suitable for beam deflection in the ultraviolet spectral range, featuring high reflectivity across a broad spectrum. The beam reflects off the metal coating surface without introducing chromatic aberration. Since metal coatings are prone to oxidation, discoloration, or peeling in high-humidity environments, LBTEK's metal-coated mirrors are protected with a layer of silicon dioxide to isolate the metal coating from direct contact with air, preventing oxidation and preserving optical performance. Compared to standard UV-enhanced aluminum-coated mirrors, the cost-effective version has relatively inferior surface quality and reflectivity but comes at a lower price.
