This is a Plano-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. The lens has a diameter of 12.5mm and a focal length of 35.0mm, making it suitable for a wide range of applications. The lens is made from the high-quality material, n-bk7 schott, which is known for its excellent optical properties.
The lens features a VIS-NIR coating on both the front and back surfaces, specifically the 'edm visnir0sp2002000' coating. This coating enhances the lens's performance in the visible and near-infrared spectrum, which spans from 400 to 1000nm. This makes the lens ideal for applications that require a broad spectral range, such as biomedical imaging, spectroscopy, and machine vision.
The lens has a spherical shape, with a radius of curvature of 18.09mm on the convex side. The center thickness of the lens is 2.4mm, while the edge thickness is 1.29mm. The lens also has a large clear aperture, which minimizes vignetting and ensures high-quality images even at the edges.
