UV Fused Silica Plano-Concave (PCV) Lenses

Applications

Designed for demanding ultraviolet (UV) applications requiring precise negative focal power: deep UV lithography, UV laser systems, spectrophotometers, and high-energy laser preconditioning. Used in semiconductor inspection tools, medical diagnostic equipment, and quantum computing setups where low absorption and high damage threshold are critical. Acts as a key component in beam shaping and homogenization modules.

Key Features

Constructed from ultra-pure fused silica (synthetic SiO₂) optimized for deep UV transmission (down to 160nm). Features a planar front surface and concave rear surface for controlled light divergence. Offers exceptional homogeneity with minimal bubbles/striae. Available with specialized UV-enhanced anti-reflective (AR) coatings to suppress ghost reflections.

Advantages Over Alternatives

Outperforms conventional glass (high UV absorption) and polymer lenses (limited thermal stability). Superior resistance to solarization under prolonged UV exposure compared to borosilicate glass. Higher laser damage threshold than crystalline materials like CaF₂. Maintains optical performance across extreme temperatures (-40°C to +150°C) without degassing or warping. Cost-effective alternative to calcium fluoride for deep UV systems.

Benefits Gained

Ensures consistent system performance via stable UV transmittance; reduces stray light through AR coatings; enables compact design integration with short focal lengths; lowers maintenance costs through radiation-hardened construction; provides design flexibility with customizable curvature radii; meets ISO 10110 standards for precision optics.
