43-557 76.2 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=457.2mm Enhanced Aluminum 250-700nm

This 43-557 model is a high-precision concave spherical mirror, boasting a diameter of 76.2 mm and a thickness at the edge of 12.7 mm. The mirror's design includes an enhanced aluminum coating, optimized for the wavelength of 588 nm, which provides excellent reflectivity in the UV range of 250-700 nm. The mirror's effective focal length (EFL) is 457.2 mm, making it suitable for a wide range of applications that require superior optical performance.

The mirror is crafted from borofloat33, a high-quality glass material known for its excellent optical transmission properties and chemical resistance. This material ensures the mirror's durability and stability, making it an ideal choice for applications that require long-term performance.

The mirror's spherical shape is achieved through a precise manufacturing process, resulting in a high-quality, concave surface with a radius of curvature (R1) of -914.4 mm. This curvature, combined with the mirror's EFL, allows for effective focusing and collection of light, enhancing the overall performance of the optical system in which it is used.

The mirror's coating, "edm denh al stdcurve," is applied to the front surface, providing excellent reflectivity and protection against environmental factors. This coating is designed to maintain its performance across the UV spectrum, ensuring reliable and consistent operation.

This mirror is available from Edmund Optics and is currently in stock, making it a readily accessible option for those in need of a high-quality, concave spherical mirror for their optical systems.
