This is a high-quality dielectric mirror, 061-5103, offered by EKSMA Optics. It is designed with a circular geometry, having a diameter of 12.7 mm and a thickness of 3 mm at the edge. The mirror is made from UVFS material, specifically identified as UVFS MAL-1965.
The mirror is coated with a dual-band coating, eks hrdb500530100010, which is specifically designed to reflect light in the 500-530nm and 1000-1060nm ranges. This makes it ideal for applications that require the reflection of light in these specific wavelengths.
The mirror is shaped as a thin lens, which suggests that it is designed to focus or diverge light. However, the specific curvature and focal length of the lens are not provided in the item data.
