35-485 12.7mm Dia. x 25.4mm EFL; 90° Protected Gold 100A; Off-Axis Parabolic Mirror Protected Gold 700-10000nm
The 35-485 is a high-quality Off-Axis Parabolic Mirror, sourced from the renowned optical vendor, Edmund Optics. This mirror, with a diameter of 12.7mm and a protected gold coating, is designed for use in the infrared spectrum, specifically between 700nm and 10000nm.
The mirror's geometry is defined by a 12.7mm PFL (Pupil Fill Length) and a 25.4mm EFL (Effective Focal Length). The off-axis angle is 90 degrees, and the mirror's aperture is 19.05mm. The radius of curvature is 25.4mm, indicating a parabolic shape that is optimal for focusing or collimating light.
The mirror is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The protected gold coating, denoted as 'edm prgold 700-10000', ensures high reflectivity across the specified infrared wavelength range. This coating is also known for its durability and resistance to environmental factors, making it suitable for various applications.
