This is a 50mm diameter by 100mm focal length double-convex lens, specifically designed for the visible to near-infrared spectrum (VIS-NIR), covering the wavelength range of 400-1000nm. The lens is sourced from the reputable vendor, Edmund Optics.
The lens geometry is characterized by a double-convex shape, featuring a 101.63mm radius of curvature on the first surface and a -101.63mm radius on the second surface, creating a symmetrical design. The lens has a thickness of 3.76mm at the edge and 10mm at the center, with a back focal length of 96.65mm. The lens is made of the popular optical material, n-BK7 Schott, which is known for its excellent optical properties and versatility.
The lens features a VIS-NIR coating, specifically the EDM VISNIR0SP2002000 coating, on both the front and back surfaces. This coating is designed to enhance the lens' performance in the visible to near-infrared spectrum, reducing surface reflections and improving transmission.
This lens is ideal for applications that require high-quality imaging or light collection in the VIS-NIR spectrum, such as scientific research, machine vision, or biomedical imaging.
