Plano-convex lens element #25 series

fused silicalaser

Overview
TECHSPEC® Laser Line Coated Fused Silica Plano-Convex (PCX) lenses are optimized for maximum throughput at the 785 nm design wavelength. Intended for low-power HeNe, diode and Nd:YAG laser sources, these lenses use laser-line V-Coat anti-reflective coatings with maximum reflectance <0.25% per surface at the design wavelength to reduce reflection losses in multi-element optical assemblies.

Key Features

• <0.25% maximum reflection per surface at 785 nm (R_abs <0.25% @ 785 nm)
• Diameter range: 5 mm – 50 mm
• EFL range: 10 mm – 250 mm
• Fused silica substrate
• Laser-line V-Coat AR optimized for 785 nm (other options: 405, 532, 1064, 1550 nm)

Common Specifications

• Bevel: Protective as needed
• Substrate: Fused Silica
• Coating: 785 nm V-Coat (laser-line V-Coat AR)
• Coating specification: R_abs <0.25% per surface @ 785 nm
• Design Wavelength (DWL): 785 nm
• Diameter range: 5 mm to 50 mm
• EFL range: 10 mm to 250 mm
