36x5 mm protective lens designed for 10KW fiber laser cutting applications, helping shield the cutting head optics from dust, smoke, and cutting debris.
36x5 10KW Protective Lens for Fiber Laser Cutting Heads
The 36x5 10KW Protective Lens is a fused-silica protective window sized at 36mm diameter x 5mm thickness, rated for fiber laser cutting heads running up to 10kW. 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.
At higher cutting power, the protective window at the head has to handle more thermal load from reflected and scattered energy, which is why thickness and diameter are matched to a power rating rather than kept the same across the whole range. The 36x5, 10kW-rated version is built for heads specified at that diameter and power class - it is a routine, sacrificial wear part, not a permanent fixture, and is meant to be replaced once pitting, haze or a drop in cut quality shows up. Keeping this window in good condition protects the costlier focusing and collimation lenses sitting behind it inside the head.

Benefits of the 36x5 10KW Protective Lens
Features
A 36mm x 5mm 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 on high-power machines.
How to Confirm You Need This Size
Check your cutting head's specified lens diameter and thickness against 36x5mm.
Confirm your machine's rated power falls within the 10kW class this lens covers.
Compare against the 34x5 and 30x5 variants 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.
