This is the 80D20ER.2, a 203.2 mm diameter Borofloat broadband metallic mirror, manufactured by MKS/Newport. The mirror is 29.5mm thick and features a protected silver coating, optimized for use within the wavelength range of 480-20000nm.
The mirror is designed in a circular shape, which is the standard for many optical applications due to its symmetry and ease of integration. The base material of the mirror is Borofloat33, a type of glass known for its high chemical resistance, making it suitable for use in various environments.
The mirror is coated with Newport's ER.2 coating on the front side, which is specifically designed for broadband applications. This coating ensures high reflectivity across a wide range of wavelengths, making it ideal for use in diverse optical systems.
The mirror is categorized as a thin lens, indicating that its thickness is significantly less than its diameter. This design feature reduces weight and potential optical aberrations, making it a practical choice for many applications.
