HO-BXL12.5-1.6C 12.5mm Dia. N-BK7 Double-Convex Lens; EFL=20mm Single Layer MgF2
This HO-BXL12.5-1.6C lens is a high-quality optical component from Holmarc Opto-Mechatronics, a renowned vendor in the field. It is a double-convex spherical lens, characterized by its circular base shape and a diameter of 12.5mm. The lens has a thickness of 2mm at the edge, making it suitable for various optical applications.
The effective focal length (EFL) of this lens is 20mm, which is a critical parameter in lens selection. The first radius of curvature (R1) is 20.157308mm, and the second radius of curvature (R2) is -20.157308mm, indicating the lens's double-convex nature. The inner and outer radii are both zero, suggesting a symmetrical lens design.
The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties. It is designed to work with a wavelength of 587.6nm. The lens features a single layer of MgF2 coating on both the front and back surfaces, denoted as 'hol mgf2 0 aoi'. This coating enhances the lens's performance by reducing reflection and increasing transmission.
