The HO-BXL25-02C is a 25mm diameter Double-Convex lens, manufactured by Holmarc Opto-Mechatronics. This lens is made from N-BK7, a popular optical glass, and features a high-quality single layer MgF2 coating on both the front and back surfaces.
The lens has a focal length of 50mm, often denoted as EFL (Effective Focal Length), making it suitable for a wide range of optical applications. The double-convex geometry, characterized by two spherical surfaces that curve outwards, provides excellent focusing capabilities.
The lens has a thickness of 2mm at the edge, and the radii of curvature for the first and second surfaces are 51.27334mm and -51.27334mm respectively. The inner and outer radii are both zero, indicating a uniform curvature across the lens.
The lens is designed to operate at a wavelength of 587.6nm, which is the dominant wavelength in the visible spectrum. The MgF2 coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and minimizing losses.
