Plano-convex lens element #38-707

cylindricalfused silicalaser

Overview
TECHSPEC® Laser Grade Plano‑Convex (PCX) lenses are engineered for high‑energy Nd:YAG laser systems used in cutting, machining and welding. The precision fused silica substrate (Corning 7980), with λ/10 transmitted wavefront accuracy and 10‑5 surface quality, minimizes scatter and preserves beam quality. Lenses are available uncoated or with high laser‑damage‑threshold (LDT) anti‑reflection (AR) coatings optimized for common Nd:YAG wavelengths to maximize transmission.
