095-0130R-400 50.8 mm Dia. N-BK7 Protected Gold Spherical Plano-Concave Mirror; t=10mm 900nm
This is a 095-0130R-400 Protected Gold Spherical Plano-Concave Mirror, sourced from EKSMA Optics. The mirror has a diameter of 50.8 mm and a thickness of 10 mm at the edge. It is designed for use with a wavelength of 900 nm and is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The mirror's geometry is spherical, with a radius of curvature (R1) of -400 mm, resulting in a focal length of -200 mm. This negative focal length indicates that it is a concave mirror, which brings parallel rays of light to a focus.
The mirror is coated with a protected gold coating, specifically EKS 0030protgold900, which provides high reflectivity in the infrared region of the spectrum. The 'protected' nature of the coating ensures that the gold layer is not exposed to environmental factors, increasing the durability and longevity of the mirror.
