34-179-INK 25.0mm Dia. x 400.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 34-179-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, has a diameter of 25.0mm and a thickness at the edge of 2.82mm, which gradually increases to a center thickness of 3.2mm. The effective focal length (EFL) of this lens is 400.0mm, making it suitable for a variety of optical applications.
The lens's front and back surfaces are coated with edm vis ext, a coating specifically designed for the visible spectrum (VIS-EXT), enhancing its performance in the 350-700nm wavelength range. This coating is crucial for applications that require high transmission and low reflection in the visible light spectrum.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens. The back focal length (BFL) of the lens is 397.89mm. The lens material is n-bk7 schott, a common optical material known for its excellent optical properties and versatility.
