097-0125FR-3000 76.2 mm Dia. N-BK7 Enhanced Silver Plano-Concave Spherical Mirror; t=12.7mm 600-1100nm

This is a 097-0125FR-3000 model mirror, manufactured by EKSMA Optics, a renowned vendor known for its high-quality optical components. The mirror has a diameter of 76.2 mm and a thickness of 12.7 mm at the edge, making it a robust and stable optical element.

The mirror is made of N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties and wide transparency range. This particular mirror is designed for use in the 600-1100nm wavelength range, making it suitable for a wide range of applications, including but not limited to, laser systems, interferometry, and optical metrology.

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, and it has an effective focal length (EFL) of -1500 mm. This curvature design allows the mirror to focus or collimate light, making it a versatile optical component in various optical systems.

The mirror's surface is coated with enhanced silver, a highly reflective coating that provides high reflectivity across the specified wavelength range. The coating is identified as 'eks enhsil600110045', and it ensures optimal performance and longevity of the mirror.
