34 × 5 mm High-Power Laser Protective Windows
Request 34 × 5 mm protective windows for a high-power cutting enquiry. Confirm the head reference and obtain part-specific performance evidence.
Exact specification and supply terms are confirmed in the quotation.
Product identity & nominal size
This page is for buyers requesting the 34 mm diameter, 5 mm thickness configuration in a high-power cutting context. High-power describes the procurement requirement here; no tested kW grade is claimed for an unqualified part.
- Include laser operating power and wavelength as requirement inputs.
- Request coating, absorption and damage-test evidence for the exact quoted configuration.
- Approve the power-related acceptance criteria before a sample or batch order.
Available nominal sizes
Choose a nominal size to prepare an enquiry. Listed dimensions do not establish stock, optical grade or verified compatibility.
1 nominal size options
Position & head reference
Confirm the installation position from your exact head documentation. Market references are shown separately and remain subject to part-level checking.
High-power qualification documents
For a 34 × 5 mm high-power cutting enquiry, request the evidence for the exact quoted configuration before approving a replacement. No verified kW grade is published. Size, appearance and a head-maker reference do not establish the power capability of the supplied part.
- Confirm material and coating identification, intended wavelength and operating conditions.
- Request transmission, absorption and LIDT documents with test methods and conditions where required by your acceptance specification.
- Link each qualification document to the quoted part or batch.
Typical application enquiry
Fiber laser cutting procurement; the required head, wavelength and operating conditions belong in the enquiry.

Read the cross-reference guide →Frequently Asked Questions
What should I check for 34 × 5 mm?
This page is for buyers requesting the 34 mm diameter, 5 mm thickness configuration in a high-power cutting context. High-power describes the procurement requirement here; no tested kW grade is claimed for an unqualified part.
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.
