HO-BVL50-10B 50mm Dia. N-BK7 Double-Concave Lens; EFL=-500mm BBAR 400-700nm
This is a HO-BVL50-10B 50mm diameter N-BK7 double-concave lens, featuring an effective focal length (EFL) of -500mm and broadband anti-reflection (BBAR) coating optimized for the 400-700nm wavelength range. The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor known for high-quality optical components.
The lens is designed with a spherical geometry, having a diameter of 50mm and a center thickness of 2.5mm. Its concave-concave base shape is circular, with radii of curvature R1 and R2 measured at -522.248979mm and 522.248979mm, respectively. The lens's inner and outer radii are both 0mm, indicating a symmetrical design.
The lens is made of N-BK7 glass, a popular material for optical applications due to its excellent optical properties. The BBAR coating on both the front and back surfaces of the lens reduces reflection and increases transmission across the specified wavelength range.
