Dual Band Laser Mirror / TFMMW-50.8C08-532/1064

This mirror is compatible with Nd-YAG lasers and fiber lasers (up to 2nd harmonic) and covers two wavelength bands with a single mirror.

In addition to the fundamental wave of YAG and fiber lasers, it covers up to the 2nd harmonic and achieves a high reflectivity of over 99% in the two bands.
Due to the high reflectivity, the amount of light does not decrease significantly even if the mirror is reflected multiple times.
The use of dielectric multilayer mirror coating makes the mirror surface scratch-resistant and cleanable.
The coating absorbs little light, resulting in little change over time and withstanding continuous laser irradiation.

Guide

We can also manufacture mirrors in sizes and wavelength characteristics other than those listed in the catalog. Please use the inquiry sheet.
Surface Flatness Guaranteed Mirror (HTFM) with accuracy guarantee after surface coating is also available.

Attention

The reflectance wavelength characteristics of the dielectric multilayer film vary depending on the polarization state of the incident beam. P-polarized light has lower reflectance compared to S-polarized light, and the reflection band also becomes narrower.
The specified reflectance is represented as the average of the reflectance for P-polarized and S-polarized light.
When used at angles other than 45 degrees, there is a possibility of lower reflectance.
When used not in adaptive wavelength, reflectance may be lower.
