CM750-075-E04 Dia:75 mm Concave Mirror; 1280-1600nm; f=75 mm IR Dielectric

The CM750-075-E04 is a concave mirror offered by Thorlabs, a leading vendor in the optical components industry. This mirror, with a base shape of a circle, has a diameter of 75 mm and a thickness that varies from 12 mm at the center to 16.7 mm at the edge.

The mirror's geometry includes an effective focal length (EFL) of 75 mm and a radius of curvature (R1) of -150 mm, indicating a strongly curved surface. The mirror is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.

The CM750-075-E04 is designed to operate within the wavelength range of 1280-1600 nm, making it suitable for near-infrared (NIR) and short-wave infrared (SWIR) applications. It features a broadband anti-reflection coating, specifically the Thorlabs E04VISIBLED12801 coating, on the front surface to minimize reflection losses and enhance transmission within the specified wavelength range.

The mirror's spherical shape ensures a smooth and regular curvature, which is essential for maintaining image quality in optical systems. This mirror is an excellent choice for applications requiring high-quality reflective performance in the NIR and SWIR regions.
