110-5219E 25.4 mm Dia. x 200 mm FL; Uncoated; Plano-Convex Lens
The 110-5219E is a Plano-Convex lens, a type of spherical lens, sourced from EKSMA Optics. This lens boasts a diameter of 25.4 mm and a focal length of 200 mm, making it suitable for a wide range of optical applications. The lens is uncoated, which means it does not have any additional layers to alter or enhance its optical properties.
The lens's geometry is defined by its edge thickness of 3 mm and center thickness of 4 mm. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is determined by a radius of 83.6 mm.
The lens is made from CAF2 (Calcium Fluoride), specifically the variant known as MAL-1963. This material is chosen for its excellent optical properties, including a high transmission rate in the ultraviolet region of the spectrum, making it ideal for applications that require UV transparency. The lens operates at a wavelength of 2940 nm.
