The 38-880 is a dielectric mirror with a circular base shape and a diameter of 12.7mm, sourced from the reputable vendor Edmund Optics. This mirror has a thickness of 6.35mm and is made of fused silica, identified as fused sil mal-1965 in the material database.
The mirror's primary function is to reflect light at a specific wavelength, which, in this case, is 515nm. The coating on the front surface, edm dcurv388800aoi, is designed to optimize the reflection of light at this wavelength.
The mirror's shape is that of a thin lens, which suggests that it may have some focusing capabilities. However, this is not explicitly stated in the provided data.
The weblink associated with this item indicates that it is currently in stock, providing users with the assurance of immediate availability. This mirror would be an ideal component for systems utilizing Yb:YAG lasers, particularly those operating at or near the 515nm wavelength.
