UV Fused Silica Plano-Convex (PCX) Lense

Applications

Widely used in high-precision optical systems requiring UV transparency and thermal stability: semiconductor photolithography, UV laser beam shaping, spectroscopy instruments, aerospace imaging systems, and medical diagnostic equipment. Ideal for applications needing minimal autofluorescence and superior damage resistance under intense radiation.

Key Features

Fabricated from ultra-pure synthetic silica (UV-grade fused silica) with <1 ppm metallic impurities. Features a plano-convex design optimized for infinite conjugate ratios, reducing spherical aberration when curved surfaces face collimated light. AR coatings enhance transmission across deep UV to near-IR spectra.

Advantages Over Alternatives

Outperforms standard BK7 glass in UV transmission (down to 160 nm vs. 350 nm) and thermal shock resistance (coefficient of expansion ≈5.5×10⁻⁷/°C). Lower birefringence than crystalline materials like calcium fluoride. Resists solarization under prolonged UV exposure.

Benefits Gained

Enables sub-micron resolution in lithography tools; extends service life in high-power laser systems due to high laser damage thresholds; reduces stray light via anti-reflective coatings; maintains structural integrity under thermal cycling.
