This is a 14GM-1-200 25.4 mm Dia. UVFS Plano-Concave Mirror, a high-quality optical component sourced from Standa. The mirror has a base shape of a circle with a diameter of 25.4 mm and a thickness of 6 mm, making it suitable for a wide range of optical applications.
The mirror's geometry is spherical, with a radius of curvature (R1) of -200 mm, resulting in a focal length (EFL) of -100 mm. This negative focal length indicates that it is a concave mirror, which focuses incoming light to a point on the same side of the mirror as the light source.
The mirror is made of UVFS material with the ID 1965 and is coated with protected gold on the front surface. This coating is specifically designed for a wavelength of 750 nm, enhancing the mirror's reflectivity at this wavelength. The 'protected' nature of the coating ensures that it is resistant to environmental factors, increasing the mirror's durability and lifespan.
