This off-axis parabolic mirror, sourced from Edmund Optics, is a high-quality optical component designed for precision applications. With a diameter of 12.7 mm and a protected aluminum coating, it offers excellent durability and resistance to environmental factors. The mirror's geometry, featuring a 25.4 mm PFL (back focal length) and a 50.8 mm EFL (effective focal length), is optimized for off-axis performance, making it ideal for systems where a clear aperture is required. The mirror's 90° off-axis angle and a radius of curvature of 50.8 mm further enhance its suitability for a wide range of optical systems. The coating on the front surface, identified as 'edm dprotal300200000', ensures high reflectivity and longevity. This mirror is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The mirror's off-axis parabolic shape ensures minimal spherical aberration, making it a reliable choice for various applications.
