HO-BVL50-1.6C 50mm Dia. N-BK7 Double-Concave Lens; EFL=-80mm Single Layer MgF2
This HO-BVL50-1.6C 50mm Dia. N-BK7 Double-Concave Lens is a high-quality optical component sourced from Holmarc Opto-Mechatronics. It is designed with a base shape of a circle and features a double-concave geometry, making it suitable for a wide range of optical applications.
The lens has a diameter of 50mm and a center thickness of 2.5mm. It boasts an effective focal length (EFL) of -80mm, which is a critical parameter for determining the lens's focusing power. The inner and outer radii are 0, indicating a symmetrical design.
The lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material is identified by the Material ID [n-bk7 schott] in the item data. The wavelength for this lens is 587.6nm.
The lens is coated with a single layer of MgF2 on both the front and back surfaces. This coating, denoted as 'hol mgf2 0 aoi', is designed to enhance the lens's performance by reducing reflection and increasing transmission.
