31-394-577 203.20 mm Dia. Protected Silver Flat Mirror Protected Silver 450-10000nm

The 31-394-577 is a 203.20 mm diameter Protected Silver Flat Mirror, sourced from the reputable optical vendor, Edmund Optics. This mirror is designed for use within the wavelength range of 450-10000nm, making it a versatile choice for a wide range of optical applications.

The mirror's base shape is circular, a common choice for many optical systems due to its symmetry and ease of alignment. The geometry of the mirror includes a diameter of 203.20mm and a thickness of 38.1mm, providing a substantial and robust platform for optical interactions.

The mirror's coating is a key feature, with a front-facing Protected Silver coating (edm dprotsil3001000). This coating is designed to provide high reflectivity across the specified wavelength range, while also offering protection against minor surface damage and tarnishing.

The material of the mirror is Zerodur, a high-quality glass-ceramic material manufactured by Schott AG. Known for its low thermal expansion coefficient, Zerodur offers excellent dimensional stability and precision, making it a popular choice for high-performance optical components.

The mirror is classified as a Thin Lens, indicating that its thickness is significantly less than its diameter, and its curvature is relatively flat. This classification suggests that the mirror is designed for minimal optical distortion, providing clear and accurate reflections.
