34-178-INK 25.0mm Dia. x 200.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 34-178-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 2.44mm, while the center thickness is 3.2mm. The effective focal length (EFL) of this lens is 200.0mm, making it suitable for a variety of optical applications.
The lens's front and back surfaces are coated with edm vis ext, a type of coating that enhances its performance in the visible spectrum, specifically between 350-700nm. This coating is designed to increase transmission and reduce reflection, making it an ideal choice for applications that require high light transmission.
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 197.89mm. The lens is made of n-bk7 schott, a popular optical material known for its excellent optical properties and versatility.
