This is a HO-BXL50-04B 50mm diameter N-BK7 double-convex lens, featuring an effective focal length (EFL) of 200mm 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 (Convex-Convex) type with a circular base shape. It has a diameter of 50mm and a thickness edge of 3mm. The front and back surfaces of the lens have BBAR coating (hol bbbar 0 aoi) to minimize surface reflections and improve transmission. The lens's inner and outer radii are 0, and the radii of curvature are r1=207.609154 and r2=-207.609154.
The N-BK7 material (Schott) is a popular choice for optical elements due to its excellent optical properties, including low optical dispersion and high homogeneity. The lens is designed for the 587.6nm wavelength, making it suitable for various applications, such as imaging, beam shaping, and focusing.
