35-543 50.8mm Dia. x 615.3mm EFL; 15° Protected Gold 100A; Off-Axis Parabolic Mirror Protected Gold 700-10000nm

The 35-543 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 304.8mm pitch-focal length (PFL) and an effective focal length (EFL) of 615.3mm, offering a generous working distance. The off-axis angle of 15°, combined with a 13mm aperture, ensures excellent light collection and minimal aberrations. The radius of curvature is 609.6mm, further enhancing the mirror's optical performance.

The mirror is made from N-BK7 Schott glass, a material known for its excellent optical properties and durability. The front surface is coated with Edmund Optics' proprietary protected gold coating (edm prgold 700-10000), which provides high reflectivity across the entire operational wavelength range. This coating also ensures excellent environmental stability, making the mirror suitable for use in harsh conditions.
