CM254-075-E03 Dia:1 in Concave Mirror; 750-1100nm; f=75 mm NIR Dielectric

The CM254-075-E03 is a concave mirror with a diameter of 25.4 mm, manufactured by Thorlabs. This mirror is designed for use in the near-infrared (NIR) spectrum, specifically between 750 and 1100 nm. The mirror's spherical shape and 75 mm focal length (f=75 mm) make it suitable for a wide range of optical applications.

The mirror's base shape is circular, with a thickness of 6.5 mm at the edge and 6 mm at the center. This asymmetry in thickness is common in optical components and helps to maintain the mirror's structural integrity. The mirror's effective focal length (EFL) is 75 mm, which is the distance from the mirror's surface to the focal point. The mirror's radius of curvature (R1) is -150 mm, indicating a concave shape.

The mirror is made from n-BK7 Schott glass, a common material in optical components due to its excellent optical properties and high damage threshold. The mirror's coating is THo E03VISIBLED75011, which is specifically designed for use in the visible and near-infrared spectrum. This coating enhances the mirror's reflectivity in its intended wavelength range.

According to the vendor's website, the CM254-075-E03 is currently in stock, indicating its availability for immediate purchase and use. The mirror's detailed specifications and the vendor's reputation make it a reliable choice for optical applications in the 750-1100 nm range.
