092-3130R-75 25.4 mm Dia. UVFS Protected Gold Spherical Plano-Concave Mirror; t=6mm 900nm

This is a 092-3130R-75 protected gold spherical plano-concave mirror, sourced from EKSMA Optics. The mirror has a diameter of 25.4 mm and a thickness of 6 mm at the edge. It is designed to operate at a wavelength of 900 nm, making it suitable for a range of applications in this spectrum.

The mirror's curvature is spherical, with a radius of curvature (R1) of -75 mm. This negative value indicates a concave shape, which focuses light to a point on the mirror's axis. The effective focal length (EFL) of this mirror is -37.5 mm, meaning it will focus incoming light to a point 37.5 mm from the mirror's surface along its optical axis.

The mirror's coating is EKS 0030protgold900, a protected gold coating that enhances its reflectivity in the infrared region of the spectrum. The 'protected' nature of the coating means it is more resistant to oxidation and other forms of environmental degradation, ensuring the mirror maintains its performance over time.

This mirror is made from UVFS Mal-1965, a material with unique optical properties that make it suitable for use in a variety of applications. The mirror's specifications and properties make it a versatile and high-performing component for optical systems operating at 900 nm.
