The 38-442-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 9.0mm, is designed for use within the visible light spectrum, specifically between 350-700nm. The lens features a front and back coating of edm vis ext, which enhances its performance within the specified wavelength range.
The lens has a thickness of 1.19mm at the edge and 2mm at the center, with a focal length (EFL) of 25mm. The front surface of the lens has a radius of curvature (R1) of 12.92mm, and the back focal length (BFL) is 23.68mm. The lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens is inked, indicating that it has been marked for identification or tracking purposes. This does not affect the lens's optical performance. The lens's base shape is circular, and its geometry is spherical. The lens's coating and material make it suitable for a wide range of optical applications.
