This is a 14-845 12.7 mm Dia. UVFS High Performance Low GDD Ultrafast Mirror, a precision optical component designed for use in high-performance laser systems. The mirror 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, a type of mirror that uses multiple layers of dielectric material to reflect light. This particular mirror has a diameter of 12.7 mm and a thickness of 6.35 mm, making it suitable for a wide range of applications. The mirror is designed to work with a wavelength of 1030 nm, which is within the 1000-1060 nm range specified in its name.
The mirror's front surface is coated with edm techult10001060, a coating specifically designed to enhance its performance in the specified wavelength range. The mirror is shaped as a thin lens, which is a type of lens with a very small thickness compared to its diameter. This shape is often used in optical systems where a flat surface is required.
