091-0115R-150 12.7 mm Dia. N-BK7 Protected Aluminium Spherical Plano-Concave Mirror; t=6mm 300nm

This product is a protected aluminium spherical plano-concave mirror, offered by EKSMA Optics. It boasts a diameter of 12.7 mm and a thickness of 6 mm at the edge, making it a compact and robust option for various applications. The mirror's concave shape, with a radius of curvature (R1) of -150 mm, allows for effective light reflection and focusing.

The mirror is made of N-BK7 Schott glass, a popular choice in optical systems due to its excellent optical properties and high damage threshold. The mirror's coating, EKS 0015PROTAL 3000, is applied to the front surface, enhancing its reflectivity and durability. This coating is specifically designed for use in the ultraviolet region, with a wavelength of 300 nm, making it suitable for applications in this spectrum.

The mirror's effective focal length (EFL) is -75 mm, indicating that it focuses light to a point 75 mm from the mirror's surface. This can be useful in various applications, including imaging systems, interferometers, and laser systems.
