The 45-427 4.0mm Dia. x 6.0mm FL is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, is designed for use in various optical applications.
The lens has a diameter of 4.0mm and a center thickness of 2.26mm, with the edge thickness measuring at 1.53mm. The effective focal length (EFL) of this lens is 6.0mm, making it suitable for applications that require a longer focal length. The radius of curvature (R1) is 3.11mm, and the back focal length (BFL) is 4.51mm. The lens does not have an inner or outer radius, indicating a uniform curvature.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This lens is designed to work with a wavelength of 587.6nm.
