34-179 25.0mm Dia. x 400.0mm FL; VIS-EXT Coated; Plano-Convex Lens VIS-EXT 350-700nm
The 34-179 is a Plano-Convex Spherical Lens, characterized by its 25.0mm diameter and 400.0mm focal length. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is made from the material n-bk7 schott, a popular choice for its high refractive index and low dispersion.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating, specific to the visual spectrum (350-700nm), enhances the lens's transmission capabilities, making it ideal for applications that require high light transmission within this range.
The lens's geometry includes a 2.82mm edge thickness and a 3.2mm center thickness. The inner and outer radii are both zero, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 206.72mm, and the back focal length is 397.89mm.
This lens is a versatile option for various applications, particularly those requiring high light transmission and precise focusing within the visual spectrum. Its robust construction and reliable performance make it a valuable addition to any optical system.
