TFA-40S06-4 40 x 40 mm Hard Glass Aluminum Flat Mirror λ/4; t=6mm

The TFA-40S06-4 is a high-quality metallic mirror from OptoSigma, designed with a rectangular base shape and a robust aluminum coating. This mirror is specifically designed for use with a wavelength of 588 nm, making it ideal for applications that require precise light reflection at this frequency.

The mirror's geometry is defined by its thickness of 6 mm and dimensions of 40 x 40 mm, providing a sturdy and reliable platform for optical experiments and systems. The mirror is made from n-BK7 Schott glass, a material known for its excellent optical properties and durability.

The aluminum coating on the front surface of the mirror is optimized for high reflectivity, with a TFA (telescope first surface aluminum) coating that has a magnesium fluoride (MGf2) protective layer. This coating ensures that the mirror maintains its high reflectivity over time, even with repeated use.

The mirror is classified as a thin lens, indicating its suitability for use in a wide range of optical systems. The TFA-40S06-4 is currently in stock and available for purchase through the OptoSigma website, making it a readily accessible option for those in need of a reliable and high-performance mirror.
