G313375000 12.7 mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm Uncoated

The G313375000 is a high-quality double-concave lens offered by Qioptiq Photonics, a leading vendor in the field of precision optics. This lens, with a diameter of 12.7 mm, is designed for use in optical systems that require concave-concave geometry.

The lens is made from N-BK7, a popular borosilicate glass known for its excellent optical properties. This material is chosen for its low optical dispersion and high Abbe number, making it an ideal choice for a wide range of applications, particularly where high image quality and color correction are essential.

The G313375000 features a center thickness of 1.5 mm and an effective focal length (EFL) of -100 mm, indicating its strong converging power. The double-concave design, with radii of curvature of -104.41 mm and 104.41 mm for the first and second surfaces, respectively, further enhances its light-bending capabilities.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflection, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
