37x7 mm protective lens designed for 10KW fiber laser cutting applications, providing a protective barrier for cutting head optics during industrial laser operations.
37x7 10KW Protective Lens for Fiber Laser Cutting Heads
The 37x7 10KW Protective Lens is a fused-silica protective window sized at 37mm diameter x 7mm thickness, rated for fiber laser cutting heads running up to 10kW. It fits 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 37x7mm format is one of the standard higher-power protective window sizes used across several fiber laser cutting head brands, and is produced in multiple power-rated variants from around 10kW up to 30kW and beyond, since the thickness needed to safely handle thermal stress scales with power. The 10kW-rated version sits at the entry point of this format's power range. Like any protective window, it is a routine, sacrificial wear part meant to be replaced once pitting, haze or a drop in cut quality shows up, so the more expensive focusing and collimation lenses behind it stay protected.

Benefits of the 37x7 10KW Protective Lens
Features
A 37mm x 7mm fused-silica window rated to 10kW, sized to seat directly into a matching cutting head's process or collimation-side lens holder.
Benefits
Protects the head's expensive focusing and collimation optics, helps maintain consistent cut quality, and keeps downtime and maintenance cost lower.
How to Confirm You Need This Size
Check your cutting head's specified lens diameter and thickness against 37x7mm.
Confirm your machine's rated power falls within the 10kW class this lens covers.
Compare against the 15kW, 20kW and 30kW versions of the same 37x7 size if your machine runs higher power.
Inspect the current window for pitting, haze or cracking before ordering.
Confirm fitment with the supplier before placing a bulk order.
