35-539 25.4mm Dia. x 387.6mm EFL; 15° Protected Gold 100A; Off-Axis Parabolic Mirror Protected Gold 700-10000nm

The 35-539 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 for use in the 700-10000nm wavelength range, making it suitable for a wide range of applications, particularly in infrared (IR) spectroscopy and imaging.

The mirror's geometry is defined by a 381mm PFL (Pupil Focal Length) and a 387.6mm EFL (Effective Focal Length), with an off-axis angle of 15°. This off-axis design allows for a wider field of view compared to traditional parabolic mirrors, making it ideal for applications requiring large apertures and wide fields of view.

The mirror is made from N-BK7 Schott glass, a material known for its excellent optical properties and high damage threshold. The front surface of the mirror is coated with Edmund Optics' proprietary EDM PRGOLD 700-10000 coating, a protected gold coating that provides high reflectivity across the entire 700-10000nm wavelength range. This coating also offers excellent environmental stability and resistance to oxidation and corrosion.
