35-516 50.8 mm Dia. x 101.6mm EFL; 60° Protected Aluminum 100A; Off-Axis Parabolic Mirror Protected Aluminum

This off-axis parabolic mirror, offered by Edmund Optics, boasts a diameter of 50.8 mm and a protective aluminum coating with a 100A rating. Its effective focal length (EFL) is 101.6 mm, and it has a 60° off-axis angle. The mirror is designed to minimize spherical aberration, making it ideal for a wide range of applications.

The mirror's geometry is defined by a 76.2 mm pupil diameter (PFL) and a radius of curvature of 152.4 mm. The off-axis angle of 60° ensures that the mirror can capture and focus light from a wide field of view. The mirror is made from N-BK7 Schott glass, a material known for its excellent optical properties and durability.

The mirror's protective aluminum coating, identified as EDM DPROTAL300200000, enhances its durability and resistance to environmental factors. This coating also ensures high reflectivity across a wide spectrum, making the mirror suitable for use in various wavelength ranges.

Please note that the mirror's specifications are optimized for a wavelength of 588 nm. This makes it particularly suitable for applications that use light at this wavelength. However, it can still be used effectively in applications that use other wavelengths, albeit with slightly reduced performance.
