This is a 092-0125FR-2000 25.4 mm Dia. N-BK7 Enhanced 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 800 nm, and its enhanced silver coating on the front surface is optimized for the spectral range of 600-1100 nm.
The mirror is a concave spherical mirror, meaning it has a spherical surface that curves inward. The radius of curvature (R1) is -2000 mm, and the effective focal length (EFL) is -1000 mm. This type of mirror is often used in optical systems to focus or collimate light.
The mirror is made of N-BK7 glass, a common and versatile optical material with a high refractive index and low dispersion. This makes it suitable for a wide range of applications, from beam shaping and splitting to imaging and laser systems.
The mirror is in stock and available for purchase. For more information, please refer to the vendor's website at https://eksmaoptics.com/optical-components/metallic-mirrors/enhanced-silver-mirrors/.
