30x5 6KW Protective Lens for Fiber Laser Cutting Heads
The 30x5 6KW Protective Lens is a fused-silica protective window sized at 30mm diameter x 5mm thickness, rated for fiber laser cutting heads running up to 6kW. It sits on the process or collimation side of the head, forming a replaceable barrier that shields the internal focusing and collimation optics from spatter, smoke and thermal stress during cutting.
The 30x5mm window size is a standard format used across several fiber laser cutting head brands for the higher-power end of common industrial heads, and the 6kW rating covers the power range most widely used in Indian sheet metal fabrication shops. Its role is the same as any protective window: it takes the direct exposure to thrown-back spatter and reflected energy during cutting, so this low-cost, easily replaced window wears out instead of the more expensive focusing and collimation lenses sitting behind it. It should be checked regularly during head maintenance and replaced once pitting or haze becomes visible.

Benefits of the 30x5 6KW Protective Lens
Features
A 30mm x 5mm fused-silica window rated to 6kW, sized to seat directly into a matching cutting head's process or collimation-side lens holder.
Benefits
Protects the head's focusing and collimation optics, helps maintain consistent cut quality, and keeps downtime and maintenance cost lower for standard sheet metal cutting operations.
How to Confirm You Need This Size
Check your cutting head's specified lens diameter and thickness against 30x5mm.
Confirm your machine's rated power falls within the 6kW class this lens covers.
Compare against the 34x5 and 36x5 formats if your head takes a different size.
Inspect the current window for pitting, haze or cracking before ordering.
Confirm fitment with the supplier before placing a bulk order.
