This is a 12.7 mm diameter Ultrafast Broadband Laser Mirror, specifically designed for use in the 700-900nm wavelength range. It is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The mirror is a dielectric mirror, which means it utilizes multiple layers of dielectric material to reflect light. This type of mirror is known for its high damage threshold, low absorption, and excellent spectral control. The mirror's geometry includes a diameter of 12.7 mm and a thickness of 6.35 mm, and it is shaped as a thin lens.
The mirror's coating is a high-performance, low Group Delay Dispersion (GDD) coating, specifically designed for ultrafast lasers. The front of the mirror is coated with "edm techultbb 700900", a coating that is optimized for the 700-900nm wavelength range.
