TFA-20C05-10 20 mm Dia. N-BK7 Flat Aluminum Mirror λ/10; t=5mm

The TFA-20C05-10 is a high-quality metallic mirror from OptoSigma, designed with a 20 mm diameter and a thickness of 5mm. This mirror is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and wide transparency range.

The mirror's coating is a front-side Optical TFA Aluminum MgF2 45, which provides a high reflectivity and durability. This coating is designed to operate at a wavelength of 588 nm, making it suitable for various applications that operate within this range.

The mirror's geometry is defined by its circular shape and thin lens design, which makes it ideal for use in optical systems where space is a constraint. The mirror's flat surface ensures that it does not introduce any spherical aberration, making it suitable for use as a reference surface or as a beam director.

The mirror is currently in stock and available for purchase through the OptoSigma website, as indicated by its weblink status. With its combination of high-quality materials, robust coating, and precise geometry, the TFA-20C05-10 is a reliable and versatile optical component for various applications.
