67-240 50mm Dia. x 150mm FL VIS-NIR Coated; UV Plano-Convex Lens VIS-NIR 400-1000nm
The 67-240 is a 50mm diameter x 150mm focal length plano-convex lens, specifically designed for 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.
The lens is made of fused silica (mal-1965), a material known for its excellent transparency in the VIS-NIR range. The front and back surfaces of the lens are coated with the EDM VIS-NIR 0SP2002000 coating, which enhances its performance by reducing surface reflections and increasing transmission in the specified wavelength range.
The lens has a planar face (R1: 68.77mm) and a convex face with a 145.2mm back focal length. The edge thickness is 2.29mm, while the center thickness is 7mm. The lens's base shape is circular, and its geometry is spherical.
This lens is an excellent choice for applications that require high-quality imaging in the VIS-NIR spectrum, such as scientific research, biomedical imaging, and machine vision systems. It is currently in stock, as indicated by its weblink status, making it readily available for your optical system needs.
