43-674 9 mm Dia. N-BK7 Concave-Convex Spherical Mirror; EFL=4.5mm Protected Aluminum 400-2000nm

This 9 mm diameter concave mirror, model 43-674, is a high-quality optical component manufactured by Edmund Optics. It boasts a focal length (EFL) of 4.5mm, making it suitable for a wide range of applications. The mirror features a protected aluminum coating, optimized for use within the 400-2000nm wavelength range, providing excellent reflectivity and durability.

The mirror's geometry is spherical, with both radii of curvature (r1 and r2) measuring -9mm, indicating a concave-convex design. This unique shape allows for precise light manipulation, making it ideal for use in complex optical systems. The mirror has a thickness of 3mm at the edge, ensuring structural integrity and minimizing potential distortions.

The mirror is made from N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and high Abbe number. This material ensures high transmission and low dispersion, making it suitable for a wide range of applications, from imaging to laser systems.
