48-670 25mm Dia. x 60mm FL Uncoated; UV Plano-Convex Lens

The 48-670 is a 25mm diameter, 60mm focal length uncoated plano-convex lens, designed for use in the ultraviolet (UV) spectrum. This lens is sourced from Edmund Optics, a leading provider of optical components.

The lens features a base shape of a circle, with a planar surface on one side and a convex surface on the other. The convex surface has a radius of curvature of 27.51mm. The lens has a thickness of 1.5mm at the edge and 4.5mm at the center, providing a balanced profile for efficient light transmission.

The lens is made from fused silica, a material with a high transmission rate in the UV spectrum. This makes it ideal for applications such as UV imaging, spectroscopy, and other UV-based research or industrial processes.

The lens is uncoated, meaning it does not have any additional layers applied to its surfaces to alter its optical properties. This can be beneficial in certain applications where maintaining the natural properties of the lens material is crucial. However, it's important to note that uncoated lenses can be more susceptible to surface damage and may have higher levels of reflection compared to coated lenses.

The lens has an effective focal length (EFL) of 60mm, which is the distance from the lens's principal point to the focal point. This information is crucial when calculating the lens's magnification or when designing an optical system around this lens.
