092-0125FR-3000 25.4 mm Dia. N-BK7 Enhanced Silver Plano-Concave Spherical Mirror; t=6mm 600-1100nm

This is a 092-0125FR-3000 model mirror, manufactured by EKSMA Optics, a renowned vendor in the optical components industry. The mirror has a diameter of 25.4 mm and a thickness of 6 mm at the edge, making it a robust and stable optical component.

The mirror is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. It is specifically designed for use in the wavelength of 800 nm, making it suitable for various applications in this spectrum.

The mirror's geometry is plano-concave, meaning it has a flat front surface and a curved back surface. The curvature of the back surface is spherical, with a radius of curvature (R1) of -3000 mm. This curvature results in a focal length (EFL) of -1500 mm, making it a negative or concave mirror.

The mirror is coated with enhanced silver on the front surface, identified as 'eks enhsil600110045'. This coating enhances the mirror's reflectivity, ensuring high-quality performance in the 600-1100 nm wavelength range.
