CM750-075-E02 Dia:75 mm Concave Mirror; 400-750nm; f=75 mm Visible Dielectric

The CM750-075-E02 is a concave mirror offered by Thorlabs, designed for use within the visible light spectrum, specifically between 400 and 750nm. This mirror, with a base shape of a circle, has a diameter of 75mm and a thickness that varies from 16.7mm at the edge to 12mm at the center.

The mirror's geometry includes an effective focal length (EFL) of 75mm, a radius of curvature (R1) of -150mm, and a shape that is spherical. The spherical shape ensures that light rays parallel to the optical axis converge at a single point, making this mirror suitable for various applications that require light concentration or collimation.

The mirror is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The front surface of the mirror is coated with Thorlabs' E02VisibleDielectric coating, designed to enhance its performance within the visible light spectrum. This coating ensures high transmission and low reflection, making it ideal for applications that require minimal light loss.
