35-617 25.4mm Dia. x 272.2mm EFL; 30° Protected Gold 100A; Off-Axis Parabolic Mirror Protected Gold 700-10000nm

The 35-617 is a high-quality Off-Axis Parabolic Mirror, sourced from the renowned optical vendor, Edmund Optics. This mirror, with a diameter of 25.4mm, is designed to offer exceptional performance in the 700-10000nm wavelength range, making it suitable for a wide range of applications in infrared spectroscopy, astronomy, and other fields where high-precision optical components are required.

The mirror's geometry is carefully crafted, with a 254mm PFL (Pupil Focal Length) and a 272.24mm EFL (Effective Focal Length). The off-axis angle is 30 degrees, which is designed to minimize spherical aberration and coma, common issues in optical systems. The mirror's radius of curvature is 508mm, and its aperture is 13.16mm, providing a wide field of view and excellent light gathering capability.

The mirror is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties and durability. The front surface of the mirror is coated with Edmund Optics' proprietary EDM PRGold 700-10000 coating, a protected gold coating that enhances the mirror's reflectivity in the specified wavelength range. This coating is designed to withstand harsh environmental conditions, ensuring the mirror's longevity and reliability.
