35-507 50.8mm Dia. x 50.8mm EFL; 90° Protected Gold 100A; Off-Axis Parabolic Mirror Protected Gold 700-10000nm

The 35-507 is a high-quality Off-Axis Parabolic Mirror, sourced from the renowned optical vendor, Edmund Optics. This mirror, with a diameter of 50.8mm, is designed for use in the 700-10000nm wavelength range, making it suitable for a wide range of applications, particularly in infrared (IR) systems.

The mirror's geometry is defined by a 25.4mm PFL (Pupil Focal Length) and a 50.8mm EFL (Effective Focal Length), with an off-axis angle of 90°. This off-axis design allows for superior optical performance in systems where a conventional parabolic mirror would introduce obscuration or vignetting. The mirror's radius of curvature is 50.8mm, and its aperture is 57.15mm.

The mirror is fabricated from N-BK7 Schott glass, a material well-known for its excellent optical properties and high damage threshold. The front surface of the mirror is coated with EDM PRGold 700-10000, a protected gold coating that provides high reflectivity across the entire operational wavelength range. This coating is designed to withstand harsh environmental conditions, ensuring longevity and reliability in your optical system.
