TFAN-25C05-4 25 mm Dia. N-BK7 Flat Aluminum Mirror λ/4; t=5mm

The TFAN-25C05-4 is a high-quality flat aluminum mirror with a diameter of 25 mm and a thickness of 5 mm. This mirror is sourced from OptoSigma, a renowned vendor known for its extensive catalog of optical elements. The mirror's base shape is circular, making it suitable for a wide range of applications that require circular symmetry.

The mirror is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. Schott, a leading manufacturer of optical glass, produces N-BK7. The mirror's coating is "opt tfan al aoi 45," which is an aluminum coating with high reflectivity. The coating is designed to operate at a wavelength of 588 nm, making it ideal for applications that operate in this wavelength range.

The mirror's geometry is defined by its diameter and thickness. The diameter is the overall size of the mirror, while the thickness is the distance between the front and back surfaces. The mirror's shape is defined as a "Thin Lens," which indicates that the mirror is thin relative to its diameter. This shape is often used in optical systems where the mirror's thickness does not significantly affect the system's performance.

According to the vendor's website, the mirror is currently in stock, indicating that it is readily available for purchase. The website also provides a direct link to the mirror's product page, allowing users to access more detailed information about the mirror if needed.
