38-479-INK 35.0mm Dia. x 50.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 38-479-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 35.0mm, is designed for use in the visible light spectrum, specifically between 350-700nm. The lens has a front and back coating of edm vis ext, which enhances its performance in the visible light range.
The lens's geometry is characterized by its edge thickness of 1.67mm and center thickness of 8.5mm. The effective focal length (EFL) is 50.0mm, and the radius of curvature (R1) is 25.84mm. The back focal length (BFL) is 44.4mm, and both the inner and outer radii are 0mm.
This lens is made of n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is designed to work at a wavelength of 587.6nm, which is the wavelength of the green line in the visible light spectrum.
