Laser Plano-Convex (PCX) Lenses
Tuniu Optics provides high-performance laser plano-convex lenses optimized for 355 nm, 532 nm and 1064 nm wavelengths. Fabricated from premium Corning 7980 substrate and equipped with high-transmission anti-reflection (AR) coatings, these lenses deliver excellent light transmittance. The Corning 7980 base material features an ultra-high laser-induced damage threshold of 20 J/cm².
Engineered for high-power laser systems, our plano-convex lenses are widely applied in education, scientific research and laser processing industries. Custom solutions for high-power laser plano-convex lenses are also available to fulfill your personalized application requirements.
