BB211 E04 2in Dia. Broadband Dielectric Mirror; 1280-1600nm

The BB211 E04 is a 2-inch diameter broadband dielectric mirror, specifically designed for use within the wavelength range of 1280-1600nm. This mirror, manufactured by Thorlabs, is a crucial component in various optical systems, offering high reflectivity and excellent durability.

The mirror's base shape is circular, with a diameter of 50.8mm and a thickness of 12mm, making it compatible with a wide range of optical setups. The mirror is made from Zerodur Schott, a material known for its excellent dimensional stability and low thermal expansion coefficient, ensuring the mirror maintains its shape and position even with temperature fluctuations.

The BB211 E04 features a front coating of tho e04visibled12801, a dielectric coating that provides high reflectivity within its specified wavelength range. This coating is applied using advanced vacuum deposition techniques, ensuring a uniform and durable finish.

The mirror's shape is that of a thin lens, which helps to minimize optical aberrations and distortions, thereby enhancing the overall performance of the optical system. The mirror's web links are valid and indicate that it is currently in stock, making it readily available for immediate use.
