43-553 76.2 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=76.2mm Enhanced Aluminum 250-700nm

The 43-553 is a high-precision concave spherical mirror, boasting a diameter of 76.2 mm and a focal length of 76.2 mm, making it an ideal choice for a wide range of optical applications. This mirror is crafted from borofloat33, a borosilicate glass known for its excellent thermal stability and chemical resistance.

The mirror's surface is treated with enhanced aluminum coating, designed to provide high reflectivity in the spectral range of 250-700 nm. This coating is applied using the electron beam deposition method, ensuring a uniform and durable layer. The mirror's front surface is specified as edm denh al stdcurve, indicating a standard curvature suitable for many optical systems.

The mirror's geometry includes a thickness of 12.7 mm at the edge, providing structural rigidity while minimizing weight. The mirror's concave shape is designed to focus light, making it suitable for use in applications such as imaging systems, laser resonators, and interferometers.

This mirror is available from Edmund Optics and is currently in stock, according to the vendor's website. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
