Laser Mirrors
A dielectric-coated reflective optic used to redirect a laser beam within a fiber or CO2 laser system's beam-delivery path.
Share requirements, quantities and a drawing if available. Specifications and supply terms require confirmation.
Overview
Laser mirrors use a multilayer dielectric coating tuned to reflect a specific wavelength — commonly 1064nm for fiber lasers or 10. 6µm for CO2 lasers — at very high reflectivity with minimal absorption loss. This makes them the standard choice for beam-delivery paths in laser cutting and welding heads, where even small absorption losses matter at high power. Procurement review should center on matching a mirror coating to a specific laser wavelength, AOI and power regime.
Key Selection Points
- Dielectric coatings can achieve very high reflectivity at a single design wavelength with low absorption loss
- Standard wavelength bands (1064nm fiber laser, 10.6µm CO2 laser) are common across this product category
- Often replaced as a routine maintenance/consumable item in laser cutting heads, similar in market pattern to laser protective windows
Applications
Laser mirrors are used inside fiber and CO2 laser cutting, welding and marking systems to redirect the beam within the optical path, and in some beam-delivery and beam-expander assemblies. They are typically specified by wavelength, angle of incidence and reflectivity requirement rather than by generic optical grade.
Spectral Performance
This module explains which spectral variables must be defined before measured performance can be reviewed. For Laser Mirrors, the module focuses on matching a mirror coating to a specific laser wavelength, AOI and power regime.
- Review measured performance against supplier or test-lab data tied to the exact configuration.
- Record wavelength region, angle of incidence and polarization with the measurement context.
- Confirm transmission, reflectance and blocking requirements against approved evidence for the selected configuration.
- Product-specific review: connect laser wavelength with coating family and document the trade-off against a general broadband mirror.

| RFQ input | What to provide |
|---|---|
| Input 1 | Use case for Laser Mirrors: document matching a mirror coating to a specific laser wavelength, AOI and power regime. |
| Input 2 | First decision pair: laser wavelength versus AOI and polarization. |
| Input 3 | Integration pair: coating family together with beam size, power regime and environment. |
| Input 4 | RFQ-specific instruction: provide wavelength, AOI, polarization, beam diameter and power context without assuming damage threshold. |
| Input 5 | Add the requested quantity and prototype or production stage. |
| Input 6 | Attach controlled drawings and identify the inspection or spectral evidence the buyer expects. |
Frequently Asked Questions
Is this the same as a laser protective window?
No — a laser protective window is a sacrificial flat window that absorbs/blocks debris in front of the focusing lens, while a laser mirror actively redirects the beam via a high-reflectivity coating. They serve different positions in the optical path.
Can I get a custom size or mount?
Laser Mirrors requires this decision to be tied to laser wavelength and AOI and polarization. Share your drawing or exact dimensions through the RFQ form and we will confirm feasibility.
Which specification should be fixed first for Laser Mirrors?
Begin with laser wavelength. It determines how AOI and polarization and coating family should be evaluated before the mechanical details are finalized.
When is Laser Mirrors a better fit than a general broadband mirror?
Choose between them by testing the requirement for matching a mirror coating to a specific laser wavelength, AOI and power regime. If that requirement is absent, the comparison product may provide a simpler procurement path.
What should an RFQ for Laser Mirrors include?
Provide wavelength, AOI, polarization, beam diameter and power context without assuming damage threshold. Also include quantity, drawing revision and the required acceptance evidence. Final availability is confirmed during quotation.
