The 38-440-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 9.0mm and a thickness at the edge of 1.28mm, while the center thickness measures 2.7mm. The effective focal length (EFL) of this lens is 10mm.
The lens's front and back surfaces are coated with EDM VIS EXT, a coating that extends the visible range of the lens. The inner radius of the lens is 0, and the outer radius is also 0, indicating a uniform curvature.
The lens is made of n-SF11 Schott, a high-index glass with excellent optical properties. The wavelength of this lens is 587.6nm, which falls within the visible light spectrum. This lens is inked, indicating that it has been marked for identification or tracking purposes.
The lens's geometry, including its diameter, thickness, and EFL, make it suitable for various applications. The EDM VIS EXT coating ensures that the lens performs optimally across the visible light spectrum, from 350 to 700nm.
