35-587 76.2mm Dia. x 89.3mm EFL; 45° Protected Gold 100A; Off-Axis Parabolic Mirror Protected Gold 700-10000nm
The 35-587 is a high-quality Off-Axis Parabolic Mirror, sourced from the renowned optical vendor, Edmund Optics. This mirror, with a diameter of 76.2mm, is designed for use in a wide range of applications, particularly where off-axis performance is critical.
The mirror's geometry is defined by a 76.2mm pupil diameter (PFL), an effective focal length (EFL) of 89.28mm, and a 45° off-axis angle. The off-axis design allows for superior performance compared to traditional parabolic mirrors, particularly in applications where the optical axis is not aligned with the mechanical axis.
The mirror is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The front surface of the mirror is coated with Edmund Optics' Protected Gold 700-10000 coating, which provides high reflectivity (over 95%) across the 700-10000nm wavelength range. This coating is also protected, ensuring durability and longevity.
