The CM254-100-P01 is a concave mirror offered by Thorlabs, a leading vendor in the optical components industry. 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 -200 mm, which corresponds to a focal length (f) of 100.0 mm. This focal length is a key parameter in determining the mirror's optical behavior. The mirror's thickness varies from 6.4 mm at the edge to 6 mm at the center, providing structural rigidity while minimizing unnecessary weight.
The mirror is made from N-BK7 Schott glass, a common and reliable material in optical systems due to its excellent optical properties and chemical durability. The mirror's coating is Thorlabs' P01 Protected Silver coating, which provides high reflectivity across a broad spectrum, including the visible range. The 'protected' nature of the coating means it has an overcoat to protect it from environmental damage, increasing the mirror's longevity and reliability.
This mirror is intended for use at a wavelength of 588 nm, making it suitable for applications that operate in this spectral region. The mirror's specifications make it a versatile component for various optical systems, including beam expanders, microscopes, and interferometers.
