This is a HO-BXL25-01B 25mm diameter N-BK7 double-convex lens, featuring an effective focal length (EFL) of 25mm and broadband anti-reflection (BBAR) coating for the 400-700nm wavelength range. The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor in the optical industry.
The lens is a Spherical Lens of the Sub Type Spherical Lens (Convex-Convex), with a base shape of Circular. It has a diameter of 25mm, a thickness edge of 2mm, and an EFL of 25mm. The first radius of curvature (r1) is 24.459612, while the second radius of curvature (r2) is -24.459612. The lens does not have an inner radius or an outer radius.
The lens is made of N-BK7 Schott, a popular optical glass with high homogeneity and low auto-fluorescence. The BBAR coating on both the front and back surfaces enhances transmission in the specified wavelength range, minimizing surface reflections and improving overall system performance.
