LASER CUTTING MACHINE PROTECTIVELENS

Physical specifications and precision

• Size Matching: Common diameters range from 20mm to 140mm, and thicknesses from 1mm to 9mm.

• Processing Precision: High-quality lenses require diameter tolerances controlled within ±0.05mm to ensure stable installation.

• Surface Quality: Focus on a score of 40-20 (US military standard scratch/pockmark level). A lower score indicates a more perfect 

surface, less prone to attracting dirt and being damaged by the laser.

Maintenance and lifespan

• Cleaning: Protective lenses are consumable parts and should be inspected daily. If contaminated by splashed debris, wipe with

 a mixture of anhydrous ethanol and ether. If this does not clean, replace immediately.

• Disposal Criteria: If any burn marks, scratches, or cracks are found on the coating, the lens must be replaced. Otherwise, localized

 overheating may cause it to shatter, potentially damaging the expensive focusing lens.
