43-549 50.8 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=508mm Enhanced Aluminum 250-700nm

This is a 43-549 50.8 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror, sourced from the renowned optical components vendor, Edmund Optics. The mirror boasts an enhanced aluminum coating, optimized for the wavelength range of 250-700nm, making it suitable for a wide range of applications.

The mirror has a base shape of a circle, with a diameter of 50.8mm and a thickness at the edge of 12.7mm. The mirror's geometry is spherical, with a radius of curvature (R1) of -1016mm, indicating a concave shape. The effective focal length (EFL) of this mirror is 508mm, which is a critical parameter for designing optical systems.

The mirror is made of Borofloat33, a high-quality borosilicate glass known for its excellent transmission properties, chemical resistance, and thermal stability. This material makes the mirror suitable for use in harsh environmental conditions.

The mirror's coating is enhanced aluminum, denoted as 'edm denh al stdcurve'. This coating provides high reflectivity across the specified wavelength range, enhancing the mirror's performance in its intended applications.
