HO-BXL25-02C 25mm Dia. N-BK7 Double-Convex Lens; EFL=50mm Single Layer MgF2
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.
This lens is available for purchase directly from the Holmarc Opto-Mechatronics website, and the link provided indicates that it is currently in stock.
