This is a 76.2mm diameter Off-Axis Parabolic Mirror, designed for use in the 700-10000nm wavelength range. The mirror is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The mirror features a 63.5mm PFL (Position From Lens) and a 127mm EFL (Effective Focal Length), making it suitable for a variety of optical applications. The off-axis angle is 90°, which is a common angle for many optical systems. The mirror's shape is defined by a radius of curvature of 127mm, and its aperture is 83.82mm.
The mirror is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high damage threshold. The front surface of the mirror is coated with Edmund Optics' Protected Gold 700-10000 coating, which provides high reflectivity and excellent environmental stability. This coating is designed to withstand harsh environments, making the mirror suitable for use in a wide range of applications.
