HO-BVL50-02C 50mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm Single Layer MgF2

The HO-BVL50-02C is a high-quality double-concave lens offered by Holmarc Opto-Mechatronics, a renowned vendor in the optical industry. This lens, with a diameter of 50mm, is designed for use in various optical systems that require concave-concave geometry.

The lens's base shape is circular, and it features a center thickness of 2.5mm. The effective focal length (EFL) is -100mm, indicating that it is a diverging lens, which spreads out light rays. The first radius of curvature (R1) is -105.759416mm, and the second radius (R2) is 105.759416mm, both of which contribute to the lens's double-concave structure.

The lens is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transparency range. The material is suitable for use across a broad spectrum, including the visible and near-infrared regions.

This lens comes with a single layer of MgF2 coating on both the front and back surfaces. This coating, applied at 0 degrees angle of incidence, reduces reflection and enhances transmission, making the lens ideal for applications requiring high light transmission.

The lens's shape is spherical, a common geometry in optical systems due to its ease of manufacturing and use. The geometry data provided ensures that the lens can be accurately modeled and integrated into various optical designs.
