Fitment

Protective window, 21.5 mm diameter by 2 mm thick, sold in 15, 20, 30 and 40 kW grades. Pick the power grade on this page; each grade has its own part number. The same nominal size at a higher kilowatt grade is a different coating tier, not a different thickness. Match diameter, thickness, and power grade to the seat in the head. Upper versus lower position was not on our spec sheet — check which seat you are replacing. Substrate and coating wavelength were not stated. Ask if the job needs the datasheet before you buy a box.
Questions
- What if it does not fit my head?
- Email support@laserparts.us with the head model and a photo before you ship anything back. A listed fit that does not seat is replaced or refunded. Unused parts in sealed packs can come back within 30 days of delivery. Typical and noted fits are confirm-first.
- How do I reorder the same part?
- Order the pack SKU (LP-W24-Q1, LP-W24-Q10, LP-W25-Q1, LP-W25-Q10, LP-W26-Q1, LP-W26-Q10, LP-W27-Q1, LP-W27-Q10). SKUs stay the same between orders, and the JSON catalog lists every one.
