G052403000 12.7 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-50mm Uncoated

This is a G052403000 12.7 mm Dia. N-BK7 Mounted Double-Concave Lens, with a focal length (EFL) of -50mm, making it a negatively powered lens suitable for various applications. The lens is sourced from Qioptiq Photonics, a renowned vendor in the optical industry, and is available for purchase on their website.

The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. This material is known for its low dispersion and high Abbe number, making it an ideal choice for applications that require high image quality and minimal chromatic aberration.

The lens has a diameter of 12.7 mm and a center thickness of 1.5 mm. The double-concave geometry, characterized by two concave surfaces with radii of curvature -52.33 mm and 52.33 mm respectively, contributes to its negative power. The inner and outer radii are both zero, indicating that the lens has no peripheral slope or edge thickness.

The lens is uncoated, meaning it does not have any anti-reflective or protective coatings. While this may result in higher reflective losses, it can also make the lens more cost-effective and suitable for applications where such coatings are not necessary.

The lens is mounted, suggesting that it is ready for immediate use in optical systems. However, the specifics of the mount are not provided in the item data. Therefore, users should verify compatibility with their intended application or system.
