The 45-590 2.5mm Dia. x 3.0mm FL is a high-quality Plano-Convex lens sourced from Edmund Optics. This lens, with a diameter of 2.5mm and a focal length of 3.0mm, is designed for use in a variety of optical applications.
The lens is uncoated, which means it does not have any additional layers to enhance light transmission or protect the surface. This can be advantageous in certain applications where the elimination of potential interferences from coating layers is desired.
The lens is made of n-lasf9 Schott, a material known for its excellent optical properties. The geometry of the lens includes a thickness of 0.47mm at the edge and 0.8mm at the center, with an effective focal length (EFL) of 3mm. The radius of curvature (R1) is 2.55mm, and the back focal length (BFL) is 2.57mm.
The lens is spherical in shape, which is a common geometry for lenses due to its ease of manufacturing and versatility. The base shape is circular, adding to its versatility in various applications.
Please note that the wavelength for this lens is 587.6nm. This information is crucial when calculating the lens's performance in specific applications.
