Laser Protective Windows
Check your partPrepare the installed model, part reference and required quantity.
Identify the window, not just its size.
The same outside dimensions can be used for different optical requirements. Use the installed head documentation or the existing part reference.
| Head & location | Head manufacturer and model; upper or lower window, or the named position in the assembly. |
|---|---|
| Physical dimensions | Outside diameter, thickness and any edge or holder requirements from the drawing. |
| Optical specification | Operating wavelength, substrate and coating requirements from the equipment documentation. |
| Part identification | Original part number, packaging label and holder or drawer reference where available. |
| Order information | Quantity, required packaging, destination and whether matching holders or seals are needed. |
Before you order.
Is a window with the same diameter interchangeable?
Dimensions alone do not establish a match. Thickness, optical specification, installation position and holder requirements must also be checked.
Can colour in the photo identify the coating?
No. Photo lighting and reflections are not a coating specification. Use the part number or the supplier documentation for the required optical properties.
Are holders and seals included?
The supply scope is agreed for the requested item. List windows, holders and seals separately so the quotation is clear.
