35-726-566 254 mm Dia. Borofloat Precision Parabolic Mirror; EFL=2540mm Protected Gold 700-10000nm

This is a 35-726-566 model parabolic mirror from Edmund Optics, featuring a 254 mm diameter and a focal length of 2540 mm. The mirror is made of borofloat33, a type of glass known for its high thermal shock resistance and low thermal expansion coefficient. This makes it an excellent choice for applications that require stability over a wide temperature range.

The mirror's surface is coated with protected gold, specifically designed for use in the 700-10000 nm wavelength range. This coating enhances the mirror's reflectivity, ensuring optimal performance in infrared applications. The gold coating is also protected, which increases its durability and longevity.

The mirror's parabolic shape is another key feature. Parabolic mirrors are used to collect or focus light, or to collimate light emanating from a source at its focus. They are often used in applications such as telescopes, solar energy collectors, and optical communication systems.

The mirror has a thickness of 44.5 mm at the edge, providing structural rigidity. The radius of curvature is 5080 mm, which, combined with the diameter and focal length, determines the mirror's parabolic shape.
