Laser Protective Windows
Find laser protective windows by nominal size and application. Compare enquiry options, check head references and request a configuration-specific quote.
Exact specification and supply terms are confirmed in the quotation.
Choose the window from the part reference
Laser protective windows, also called cover glass or debris windows, are replaceable optical components used in laser processing heads. Start with the part you need to replace: its nominal diameter and thickness, the exact head model, and its installation position. For distributors, service teams and batch buyers, this catalogue organizes enquiries; the quotation confirms the supplied specification.
- Choose a nominal size or use the identification guide.
- Keep machine operating power separate from a verified window power grade.
- Provide a part number, photo reference or drawing reference.

Prepare the cutting-head model, window position and existing part reference together. Where your machine has more than one protective window, identify each position separately.
High-Power Laser Protective Windows
Use the 37 × 7 mm route to organize holder, part-reference and high-power replacement enquiries; use the 34 × 5 mm route for configuration-specific qualification documents. Select from the head documentation, not by power alone. Neither nominal size establishes a verified kW rating.
- Request material and coating identification tied to the quoted part.
- Request the relevant transmission, absorption and damage-test documents, with test conditions.
- Confirm the head revision, mounting position and acceptance criteria before approving substitution.
Handheld laser welding
Compare nominal 18 × 2, 20 × 2, 20 × 3 and 20 × 4 mm options. Identify the welding-head model and thickness from its part list or drawing.

How to Specify
Send the seven enquiry inputs below. For repeat purchasing, keep the approved drawing revision and accepted sample reference with the order; confirm changes before substitution.
Coating & Quality Control
Ask for evidence for the quoted configuration, rather than relying on a generic product-family description.
- Material identity and grade document.
- Coating designation, intended wavelength and measurement conditions.
- Measured transmission and absorption data where required.
- LIDT method and conditions if that property is part of your acceptance criteria.
- Dimensional inspection, surface inspection and batch identification agreed in the quotation.
Applications
This selection workflow supports cutting and handheld welding procurement. Application labels describe the enquiry context; they do not establish that a particular window fits a head or handles a stated operating power.
Compatibility Matrix
Compatibility can vary by head revision, optical position and power grade. Use the references below as a purchasing guide and share the exact model or part number when available.
Verified Reference: confirmed exact-configuration evidence. Common Reference: an association recorded in existing professional research. Model Check Required: brand or series level only — share your exact head model or part number.

Read the cross-reference guide →Frequently Asked Questions
Does the listed size confirm compatibility?
No. Treat the dimensions as an enquiry starting point. Confirm the head model, revision, window position, drawing and required optical specification before ordering.
How are power grades confirmed?
Ask for evidence tied to the exact material, coating, wavelength and operating conditions of the quoted part. A machine power label or nominal window size is not a verified grade for the replacement.
What are the MOQ, stock and lead time?
Request a quotation with your size and quantity. Availability, minimum order quantity and delivery timing are confirmed for the quoted configuration.
