This is a dielectric mirror from Edmund Optics, specifically designed for use with Yb:YAG laser lines at a wavelength of 1030nm and an angle of incidence of 0-45°. The mirror is rectangular in shape, with dimensions of 6.35mm in width and height, and a thickness of 3.18mm.
The mirror is made from fused silica, which is known for its excellent optical properties, including high transparency and resistance to thermal shock. The dielectric coating on the front surface of the mirror is EDM DCURV103045AOI, which is specifically designed to enhance the mirror's reflectivity at the specified wavelength.
The mirror is designed in the shape of a thin lens, which can be beneficial in certain optical systems where thin, lightweight elements are required. The mirror is currently in stock and available for purchase through the Edmund Optics website.
