CM254-200-P01 Dia:1 in Concave Mirror; f=200.0 mm Protected Silver

The CM254-200-P01 is a concave mirror offered by Thorlabs, a leading global manufacturer of photonics equipment. This mirror, with a diameter of 1 inch (25.4 mm), is designed for use in optical systems that require a curved mirror with a specific focal length.

The mirror's geometry is spherical, with a radius of curvature (R1) of -400 mm, which corresponds to a focal length (EFL) of 200 mm. This means that the mirror will focus incoming parallel light to a point 200 mm away from the mirror's surface. The mirror's thickness varies from 6.2 mm at the edge to 6 mm at the center, providing structural rigidity while minimizing weight.

The mirror is made from N-BK7 glass, a common material in optical systems due to its excellent optical properties and high Abbe number. The front surface of the mirror is coated with Thorlabs' P01 Protected Silver coating, which provides high reflectivity in the visible spectrum, specifically at 588 nm. This coating is designed to withstand the rigors of regular use, including cleaning and handling, making it suitable for use in laboratory and industrial settings.

This mirror is currently in stock, according to the vendor's website, and is ready for immediate shipping. It is an excellent choice for anyone looking for a high-quality, reliable concave mirror for their optical system.
