Bodor Protective Lens – D38.1 x T1.6 mm
A laser protective lens (protective window) is a sacrificial consumable mounted in the cutting head. It shields the expensive focusing and collimating optics from spatter, smoke, dust and high-pressure assist gas, keeping beam quality and cut consistency stable while cutting the cost of head maintenance.
Key features
- High-purity fused silica substrate with double-sided AR coating for 1064 nm
- Transmittance above 99.5% and a coating damage threshold over 15 J/cm2
- Precision-ground diameter and thickness for a play-free fit in the drawer
- Low absorption to limit thermal focus shift at high power
- Individually packed and inspected; drop-in replacement for OEM part numbers

Installation & maintenance
- Upper (collimation) window: protects the collimating lens, replaced with the drawer cartridge.
- Lower (focus / process) window: the first barrier against spatter, replaced most often.
- Inspect every shift; replace at once on pitting, burn marks, haze, cracks or a sudden drop in cut quality.
- Handle by the edge only, clean with lint-free swabs and ethanol, and never wipe dry debris across the surface.
