32-833 76.2 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=762mm Protected Aluminum 400-2000nm

This 32-833 optical mirror, sourced from Edmund Optics, boasts a 76.2 mm diameter and a λ/4 precision. Its concave spherical shape, with a radius of curvature (R1) of -1524 mm, contributes to its exceptional optical performance. The mirror's effective focal length (EFL) is 762 mm, making it suitable for a wide range of optical applications.

The mirror is crafted from borofloat33, a borosilicate glass known for its high thermal resistance and low thermal expansion coefficient. This material ensures the mirror's stability and durability, making it an excellent choice for applications requiring precise and consistent optical performance.

The mirror's coating further enhances its capabilities. The front surface is protected with an edm dprotal300200000 coating, which provides protection in the wavelength range of 400-2000nm. This coating ensures the mirror's longevity and maintains its optical performance over time.
