How to select
Confirm the protective-window diameter, thickness, laser power, and OSPRI cutting-head model before ordering. If uncertain, send CHASE LASER a clear photo of the original lens package and cutting-head nameplate.
Important: Identical dimensions can be offered for different laser-power configurations. Compatibility must be confirmed by size, coating, power rating, and cutting-head model. Contact us for technical confirmation, availability, and quotation.
Courier freight is confirmed by destination, weight and carton size. We normally ship by DHL, UPS or FedEx with tracking.
If you are unsure about compatibility, send the cutting-head model, source model, part code or dimensions before ordering. Custom, special-order and opened optical parts are handled according to the agreed order terms.
