32-065-000 108 mm Dia. Borofloat Precision Parabolic Mirror; EFL=444.5mm Uncoated

This is a 108 mm diameter parabolic mirror from Edmund Optics, designed for precision applications. The mirror is made from borofloat33, a type of glass known for its high optical quality and resistance to thermal shock. The mirror's parabolic shape, with a radius of curvature of 889, is ideal for focusing or collimating light, making it suitable for use in telescopes, lasers, and other optical systems.

The mirror has an effective focal length (EFL) of 444.5mm, which is the distance from the mirror's surface to its focal point. This EFL, combined with the mirror's diameter, determines the mirror's light-gathering capacity and angular resolution. The mirror's thickness at the edge is 19.1mm, providing structural rigidity and resistance to deformation.

Notably, this mirror is uncoated. While coatings can enhance a mirror's reflectivity, they can also introduce complexity and cost. An uncoated mirror is a simple, cost-effective solution when high reflectivity is not required or can be achieved through other means. The mirror's wavelength is 588nm, suggesting applications in visible light systems.
