67-241 50mm Dia. x 200mm FL VIS-NIR Coated; UV Plano-Convex Lens VIS-NIR 400-1000nm
The 67-241 is a 50mm diameter, 200mm focal length plano-convex lens, specifically designed for use in the visible to near-infrared spectrum (VIS-NIR), covering the wavelength range of 400-1000nm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is made from fused silica, a material with a high transmittance across a wide range of wavelengths, making it ideal for applications in imaging, spectroscopy, and beam shaping. The front and back surfaces of the lens are coated with the EDM VIS-NIR 0SP2002000 coating, which is designed to enhance the lens's performance in the VIS-NIR spectrum.
The geometry of the lens includes a 3.53mm edge thickness and a 7mm center thickness, with a clear aperture of 50mm. The lens's front surface has a radius of curvature of 91.69mm, resulting in a back focal length of 196.19mm. The lens's shape is spherical, and it does not have any inner or outer radii.
