This HO-BXL25-06C optical lens, sourced from Holmarc Opto-Mechatronics, is a double-convex spherical lens with a base shape of a circle. The lens has a diameter of 25mm and a thickness at the edge of 2mm. The effective focal length (EFL) of this lens is 150mm. The first radius of curvature (R1) is 155.968303, and the second radius of curvature (R2) is -155.968303. The inner and outer radii are both 0.
The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties. The wavelength for this lens is 587.6nm. The lens is coated with a single layer of MgF2 on both the front and back, which is indicated by 'hol mgf2 0 aoi'. This coating enhances the lens's performance by reducing reflection and increasing transmission.
