G340072000 50 mm Dia. Front Surface Concave-Convex Mirror for Illumination System; EFL=19mm Aluminum 400-700nm

This is a G340072000 front surface concave-convex mirror, specifically designed for illumination systems. The mirror is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics. The mirror has a diameter of 50 mm and a center thickness of 3 mm, making it robust and suitable for various applications.

The mirror's effective focal length (EFL) is 19 mm, which is a crucial parameter for determining the mirror's magnification and field of view. The mirror's first and second radii of curvature (R1 and R2) are both -38 mm, indicating a concave shape. This shape is ideal for collecting and focusing light, enhancing the performance of illumination systems.

The mirror is made of n-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material makes the mirror suitable for use in the wavelength range of 400-700 nm, covering the visible light spectrum.

The mirror's front surface is coated with Qio Al Ralvis Aoi 45, an aluminum coating that enhances its reflectivity. This coating ensures efficient light reflection, contributing to the overall performance of the illumination system.
