TFA-30C05-4 30 mm Dia. N-BK7 Flat Aluminum Mirror λ/4; t=5mm by OptoSigma

OptoSigma's TFA-30C05-4 is a high-quality metallic mirror with a base shape of a circle, a diameter of 30 mm, and a thickness of 5 mm. This mirror is made of N-BK7 Schott glass, a popular material known for its excellent optical properties, making it suitable for various applications.

The mirror features a front coating of opt TFA aluminum with magnesium fluoride (MgF2) at 45 degrees, which provides high reflectivity and durability. The λ/4 specification indicates that the coating is a quarter-wave thick, optimized for normal incidence at the specified wavelength of 588 nm. This coating ensures high-quality reflection, minimizing losses and enhancing the performance of the mirror.

The mirror's thin lens shape allows for easy integration into optical systems, while its robust aluminum construction ensures long-lasting performance. The TFA-30C05-4 is currently in stock and available for purchase through the OptoSigma website, as indicated by its weblink status.
