37-989 50.8mm Dia.x 76.2mm EFL; Protected Gold 50A 90° Off-Axis Mirror Protected Gold 700-10000nm
This product is a Protected Gold 50A 90° Off-Axis Mirror, sourced from the renowned optical vendor, Edmund Optics. The mirror boasts a diameter of 50.8mm and an effective focal length of 76.2mm, making it suitable for a wide range of optical applications.
The mirror's geometry is defined by its circular shape, a parabolic profile, and a 90° off-axis angle. The off-axis angle is crucial in applications where the light path needs to be diverted without compromising the image quality. The mirror's radius of curvature is 76.2mm, and its clear aperture is 57.15mm.
The mirror is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The coating on the front surface is Edmund Optics' proprietary protected gold coating, designed to operate in the 700-10000nm wavelength range. This coating ensures high reflectivity and durability, making the mirror suitable for use in demanding optical systems.
