092-0130R-750 25.4 mm Dia. N-BK7 Protected Gold Spherical Plano-Concave Mirror; t=6mm 900nm

This is a 092-0130R-750 25.4 mm Dia. N-BK7 Protected Gold Spherical Plano-Concave Mirror, a high-quality optical component sourced from EKSMA Optics. The mirror has a base shape of a circle with a diameter of 25.4 mm and a thickness edge 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 -750 mm, resulting in a focal length of -375 mm. This negative focal length indicates that the mirror is a concave mirror, which reflects light rays towards a common point, making it ideal for focusing or imaging applications.

The mirror is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. This material is widely used in various optical systems, including lasers, beam delivery systems, and interferometers.

The mirror is coated with a protected gold coating (eks 0030protgold900) on the front surface, designed to enhance its reflectivity at the specified wavelength of 900 nm. Protected gold coatings are known for their high reflectivity, durability, and resistance to environmental conditions, making them suitable for use in harsh environments.
