35-668 25.4mm Dia. x 27.2mm EFL; 30° Bare Gold 100A; Off-Axis Parabolic Mirror Bare Gold

This Off-Axis Parabolic Mirror, offered by Edmund Optics, is a high-quality optical component designed for precision applications. The mirror boasts a diameter of 25.4mm and a PFL (Parabolic Focal Length) of 25.4mm, making it suitable for a variety of optical systems. The Effective Focal Length (EFL) is 27.22mm, which is a crucial parameter in determining the mirror's performance in a given system.

The mirror features a 30° off-axis angle, which is beneficial in applications where a straight-through beam path is not feasible. The off-axis angle also helps reduce spherical aberration, a common issue in optical systems. The mirror's a value is 13.16mm, and it has a radius of curvature of 50.8mm, further enhancing its optical performance.

The mirror is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The coating on the front surface is edm dbaregoldmodifie, a specialized bare gold coating that provides high reflectivity and durability. This coating is particularly useful in the visible spectrum, with a central wavelength of 588nm.
