HO-BXL50-20C 50mm Dia. N-BK7 Double-Convex Lens; EFL=1000mm Single Layer MgF2
This HO-BXL50-20C lens is a high-quality optical component manufactured by Holmarc Opto-Mechatronics. It is a double-convex spherical lens, characterized by its circular base shape and a diameter of 50mm. The lens has a thickness of 3mm at the edge, making it robust and suitable for various applications.
The effective focal length (EFL) of this lens is 1000mm, which is a crucial parameter in lens selection. The first radius of curvature (R1) is 1042.588965, and the second radius of curvature (R2) is -1042.588965, indicating the lens's double-convex nature. The inner and outer radii are both zero, suggesting a uniform curvature throughout the lens.
The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties. The wavelength for this lens is 587.6nm, which is within the visible light spectrum.
The lens is coated with a single layer of MgF2 on both the front and back surfaces. This coating, denoted as 'hol mgf2 0 aoi', is designed to reduce reflection and improve transmission, enhancing the lens's performance in various applications.
