Diameter 25.4mm Fused Silica Laser Protective Lens

Laser protective window is mainly used in laser cutting to prevent debris splash to damage the lens.coated with high damage threshold (>15J/cm2) anti-reflection coating to reduce the reflection,is now widely used in optical cutting,laser marking and other applications. Laser Protective Window Material : Fused Silica Diameter : 25.4mm Dimension Tolerance : ±0.1 Thickness : 4mm and 5mm Surface Quality : 40/20 Transmittance : 99.5% Clear Aperture : <80% Bevel : 0.5 x 45deg Coating : 1064nm Realpoo Optics offer high quality fused silica laser protective windows, which are designed for useing with high power fiber lasers, to protective laser optics against damage from material splatter. Laser proteictive window is coated AR coating 1064nm in both sides. The substrate of the window is normally JGS1 or Fused Silica(FS). The diameter 18mm to 55mm is available.…
