092-0125R-2000 25.4 mm Dia. N-BK7 Protected Silver Plano-Concave Spherical Mirror; t=6mm 400nm

This is a 092-0125R-2000 protected silver plano-concave spherical 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 for use with a wavelength of 400 nm and is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion.

The mirror's concave shape, defined by a radius of curvature (R1) of -2000 mm, results in a negative focal length, making it suitable for use in various optical systems where light needs to be focused. The effective focal length (EFL) of the mirror is -1000 mm, which is the distance from the mirror's center to the focal point.

The mirror's front surface is coated with EKS 0025protsil 4000, a protected silver coating that offers high reflectivity and durability. This coating ensures optimal performance and longevity, making the mirror suitable for various applications.
