The 541-7275 is a Plano-Convex Lens, a type of spherical lens, sourced from EKSMA Optics. This lens has a circular base shape and is designed for use in the ultraviolet (UV) and infrared (IR) spectrum, with a wavelength of 3000 nanometers.
The lens has a diameter of 25.4 millimeters and a thickness at the edge of 2.5 millimeters. The effective focal length (EFL) of this lens is 750 millimeters, making it suitable for applications that require a long focal length. The lens's first surface has a radius of curvature of 384.225 millimeters, while the second surface has no curvature, hence the term 'Plano'.
The lens is made from Barium Fluoride (BaF2), a material with a high transmission in the UV and IR regions. The lens does not come with any coating, which means it is uncoated. This could make it more susceptible to environmental factors, but it also means that it can be custom coated to suit specific application needs.
The lens's information, including its availability and pricing, can be found on the EKSMA Optics website. This lens is currently in stock, making it a readily available option for those in need of a Plano-Convex lens for UV or IR applications.
