TFA-2535R05-4 25 x 35 mm N-BK7 Aluminum Flat Mirror λ/4; t=5mm by OptoSigma

OptoSigma's TFA-2535R05-4 is a high-quality aluminum flat mirror designed for optimal performance in various applications. This mirror boasts a rectangular base shape with dimensions of 25 x 35 mm and a thickness of 5 mm, providing excellent stability and durability.

The mirror is made from N-BK7 Schott glass, a popular material known for its excellent optical properties, including high homogeneity, low auto-fluorescence, and superior transmittance in the ultraviolet, visible, and near-infrared spectral ranges. This makes the TFA-2535R05-4 suitable for a wide range of optical systems.

The mirror's coating is a crucial factor in its performance. It features an opt TFA aluminum coating with a magnesium fluoride (MgF2) protective layer, which provides a high reflectivity of 96% at a wavelength of 588 nm. This coating is designed to λ/4, ensuring minimal phase shift and maintaining the mirror's high reflectivity across the specified wavelength range.

The mirror's thin lens shape further enhances its performance, allowing for easy integration into various optical systems. The TFA-2535R05-4 is currently in stock and available for purchase through the OptoSigma website, making it an accessible option for those in need of a reliable and high-performing optical component.
