37x7 mm protective lens designed for 30KW fiber laser cutting applications, helping shield cutting head optics during high-power industrial laser operations.
37x7 30KW Protective Lens for Fiber Laser Cutting Heads
The 37x7 30KW Protective Lens is a fused-silica protective window sized at 37mm diameter x 7mm thickness. It is rated for fiber laser cutting heads running up to 30kW. 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 produced up to this higher power class for heavy-duty fiber laser cutting heads used on thick-plate and high-throughput lines. At 30kW, the window sees significant thermal load from reflected and scattered energy, so it is treated strictly as a routine, sacrificial wear part - checked frequently and replaced as soon as pitting, haze or a drop in cut quality appears, rather than left in place until it fails outright.

Benefits of the 37x7 30KW Protective Lens
Features
A 37mm diameter x 7mm thickness fused-silica window rated to 30kW, 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 30kW class this lens covers.
Compare against other sizes in this range if your head takes a different diameter or thickness.
Inspect the current window for pitting, haze or cracking before ordering.
Confirm fitment with the supplier before placing a bulk order.
