63-811 25mm Dia. x 125mm FL VIS-NIR Coated; UV Plano-Convex Lens VIS-NIR 400-1000nm

The 63-811 is a UV Plano-Convex Lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 25mm and a focal length of 125mm, is specifically coated for the visible (VIS) and near-infrared (NIR) spectrum, making it ideal for applications that require high transmission in these wavelength ranges.

The lens is made from fused silica, a material with a high transmittance across a wide spectrum, including the UV, VIS, and NIR regions. 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 lens's geometry is characterized by a planar front surface and a convex rear surface, with a center thickness of 3.42mm and an edge thickness of 2.04mm. The lens's effective focal length (EFL) is 125mm, and its back focal length (BFL) is 122.65mm. The lens's inner and outer radii are 0mm, indicating a symmetrical curvature.

This lens is part of the Spherical Lens (Plano-Convex) subtype, which is known for its ability to focus light without introducing significant spherical aberration. The lens's base shape is circular, ensuring uniform illumination across the entire field of view.

The lens's coating and material properties make it suitable for a wide range of applications, including but not limited to, spectroscopy, biomedical imaging, and machine vision. The lens is currently in stock, as indicated by its weblink status, and more information about it can be found on the Edmund Optics website.
