091-0115R-500 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, sourced from EKSMA Optics. It boasts a 12.7 mm diameter and a thickness of 6 mm at the edge, making it a robust and durable option for various applications. The mirror's concave shape, with a radius of curvature (R1) of -500 mm, allows for effective light reflection and focusing.

The mirror is made from N-BK7 Schott glass, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. This material is known for its low auto-fluorescence, making it suitable for applications where minimal background noise is crucial.

The mirror is coated with EKS 0015PROTAL 3000 on the front side, a protective aluminium coating designed for high reflectivity in the ultraviolet region, specifically at 300 nm. This coating ensures high-quality performance and longevity of the mirror.

The mirror's effective focal length (EFL) is -250 mm, indicating that it focuses light at a point 250 mm from the mirror's surface. This makes it ideal for applications requiring precise light focusing, such as imaging systems, interferometers, and beam manipulation systems.
