This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, with a base shape of a circle, has a diameter of 25.4mm and a thickness at the edge of 2.44mm. The thickness at the center is 4mm, and the effective focal length (EFL) is 101.6mm. The lens's front surface has a radius of curvature of 52.51mm, and the back focal length (BFL) is 98.97mm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is coated with a VIS-NIR coating, specifically edm visnir0sp2002000, on both the front and back surfaces. This coating is designed for the visible (VIS) and near-infrared (NIR) spectrum, specifically for wavelengths between 400 and 1000nm.
This lens is a great option for applications that require a high-quality lens in the VIS-NIR spectrum, such as optical systems for spectroscopy, biomedical imaging, and machine vision. The Plano-Convex design provides a wide field of view and low distortion, making it suitable for imaging applications.
