The 45-097-INK is a Plano-Convex Spherical Lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 25.0mm and a focal length of 25.0mm, is a part of their extensive catalog of optical elements.
The lens is uncoated, meaning it does not have any additional layers to alter its optical properties. However, it is inked, which is a process that involves applying a dye to the surface of the lens. This can be useful for marking or identifying the lens, or for absorbing stray light.
The geometry of the lens is defined by its diameter, thickness edge, thickness center, effective focal length (EFL), and radii. The diameter is 25.0mm, and the thickness edge is 2.43mm. The thickness center is 8.0mm, and the EFL is 25.0mm. The first radius (R1) is 16.82mm, and the back focal length (BFL) is 20.22mm. The lens does not have an inner radius or an outer radius.
The lens is made of N-SF5 Schott, a high-quality optical glass. The wavelength of operation is 587.6nm. This lens is a versatile and reliable option for various optical applications, thanks to its robust construction and precise specifications.
