5121 50.8 mm Dia. Borofloat 33 Broadband Dielectric Mirror; t=12.5 mm 450-700nm

This is a high-quality dielectric mirror from MKS/Newport, specifically the 5121 model. It boasts a diameter of 50.8 mm and a thickness of 12.5 mm, making it a substantial and robust optical component. The mirror is made from Borofloat 33, a low-thermal-expansion glass ceramic known for its excellent optical properties and durability.

The mirror's primary function is to reflect light within a specific wavelength range, which in this case is from 450 to 700 nm. This broadband reflection capability makes it versatile for various applications, including but not limited to, laser systems, interferometry, and optical spectroscopy.

The coating on the front surface of the mirror is a new 51x10fromfigure, which is designed to enhance the mirror's reflective properties within the specified wavelength range. The mirror's thin lens shape further contributes to its optical performance, ensuring minimal distortion and high-fidelity light transmission.
