25mm Dia. x 100mm FL Double-Convex Lens with VIS-EXT Coating from Edmund Optics
This optical lens, sourced from Edmund Optics, boasts a 25mm diameter and a focal length of 100mm, making it suitable for a wide range of applications. Its double-convex shape, characterized by two spherical surfaces that curve outward, contributes to its impressive light-gathering capabilities.
The lens is constructed from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures that the lens delivers clear, high-resolution images across a wide spectrum of wavelengths, specifically from 350 to 700nm.
The lens features VIS-EXT coatings on both the front and back surfaces. These coatings are designed to enhance the lens's performance in the visible light spectrum, further improving image quality and reducing unwanted reflections.
The geometry of the lens includes a thickness of 2.48mm at the edge and 4mm at the center. The back focal length is 98.95mm, and the radii of curvature for the first and second surfaces are 103mm and -103mm, respectively.
