35-513 50.8mm Dia. x 152.4mm EFL; 90° Protected Gold 100A; Off-Axis Parabolic Mirror Protected Gold 700-10000nm

This off-axis parabolic mirror, sourced from Edmund Optics, is a high-quality optical component designed for use in a wide range of applications. With a diameter of 50.8mm and a protective gold coating, it offers excellent performance and durability.

The mirror has an effective focal length (EFL) of 152.4mm, which determines the distance between the mirror and the focal point where light rays converge. This particular model has a 90° off-axis angle, meaning it deviates from the optical axis by 90 degrees. This design is often used in systems where a central obscuration is not desirable.

The mirror is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high damage threshold. The protective gold coating, designated as EDM PRGOLD 700-10000, is applied to the front surface of the mirror. This coating is designed to enhance the mirror's reflectivity in the 700-10000nm wavelength range, making it suitable for use in infrared applications.

In terms of geometry, the mirror has a parabolic shape with a radius of curvature of 152.4mm. The PFL (Parallel to Focal Length) dimension is 76.2mm. This information is crucial for designing and integrating the mirror into an optical system.
