43-340 25.4 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=50.8mm Protected Gold 700-10000nm

The 43-340 is a 25.4 mm diameter concave spherical mirror, precision engineered for optimal performance in the 700-10000nm wavelength range. Sourced from the reputable optical vendor, Edmund Optics, this mirror is designed with a protected gold coating, ensuring durability and high reflectivity.

The mirror's geometry is defined by a diameter of 25.4 mm, a thickness of 6.35 mm at the edge, and a focal length (EFL) of 50.8 mm. The concave spherical shape, with a radius of curvature (R1) of -101.6 mm, is ideal for a wide range of optical applications.

The mirror is crafted from borofloat33, a borosilicate glass known for its excellent transmission properties and chemical resistance. This material makes the mirror suitable for use in harsh environments and applications requiring high precision.

The protected gold coating (edm prgold 700-10000) on the front surface ensures high reflectivity across the specified wavelength range. This coating is designed to withstand the rigors of regular use, providing a reliable and consistent performance.
