50mm Diameter x 150mm FL Double-Convex Lens with VIS 0° Coating from Edmund Optics
This optical lens, offered by Edmund Optics, is a 50mm diameter x 150mm focal length (FL) double-convex lens, designed for use within the visible light spectrum (425-675nm). The lens is constructed from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion properties.
The lens features a double-convex geometry, characterized by two spherical surfaces that curve outwards. This design is advantageous for applications requiring a wide field of view and low spherical aberration. The lens has a diameter of 50mm, a thickness at the edge of 4.9mm, and a center thickness of 9mm. The effective focal length (EFL) is 150mm, and the back focal length (BFL) is 147mm.
The lens is coated with a VIS 0° coating on both the front and back surfaces. This coating, standard from Edmund Optics, is designed to improve transmission and reduce reflection within the visible light spectrum. The coating curve is not specified in the data, but it is typically a standard curve optimized for general use.
