35-489 12.7mm Dia. x 50.8mm EFL; 90° Bare Gold 100A; Off-Axis Parabolic Mirror Bare Gold
The 35-489 is a high-quality Off-Axis Parabolic Mirror, sourced from the renowned optical components vendor, Edmund Optics. This mirror is designed with a base shape of a circle, featuring a diameter of 12.7mm and a PFL (Parabolic Focal Length) of 25.4mm. The Effective Focal Length (EFL) is 50.8mm, making it suitable for a wide range of optical applications.
The mirror boasts an off-axis angle of 90 degrees, which is a significant feature for applications requiring off-axis reflectivity. The aperture (a) of this mirror is 19.05mm, and it has a radius of curvature of 50.8mm. The material used for this mirror is n-BK7 Schott, a high-grade optical glass known for its excellent optical properties.
The mirror is coated with edm dbaregoldmodifie on the front, which is a specialized bare gold coating known for its high reflectivity and durability. This coating is designed to operate at a wavelength of 588nm, making it ideal for applications that require high reflectivity at this specific wavelength.
