TFAN-25C05-20 25 mm Dia. N-BK7 Flat Aluminum Mirror λ/20; t=5mm

The TFAN-25C05-20 is a high-quality metallic mirror from OptoSigma, designed with a flat surface and a 25 mm diameter. This mirror is specifically engineered for use at a wavelength of 588 nm, making it an ideal choice for applications that require precise light reflection at this wavelength.

The mirror is made from N-BK7 Schott glass, a popular material in optical systems due to its excellent optical properties and high damage threshold. The N-BK7 Schott glass ensures high transmission and low auto-fluorescence, making it suitable for a wide range of applications.

The mirror's coating is a crucial component of its design. It features an opt Tfan Al Aoi 45 coating on the front surface, which is a highly reflective aluminum coating. This coating is known for its high reflectivity and durability, ensuring reliable performance even under demanding conditions.

The mirror has a thickness of 5mm, which is thin enough to minimize unwanted optical effects while still providing robustness and stability. The mirror's thin lens shape further enhances its performance by reducing weight and potential distortions.
