This is a Plano-Convex lens with a diameter of 25.4 mm, sourced from Alkor Technologies. The lens is made of BaF2, a material with a refractive index that varies with wavelength, making it suitable for a wide range of applications. The lens has an effective focal length (EFL) of 63.5 mm, which is the distance from the lens's center to the focal point when the lens is placed in an optical system.
The lens's geometry includes a thickness of 2 mm at the edge and 5 mm at the center. The inner radius is 0, and the outer radius is also 0, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is defined by a radius of 28.38 mm.
The lens does not come with any coating, as indicated by the empty "coating" field in the item data. This means that the lens will not have any additional protective or enhancing layers, and its performance will be determined solely by its base material and geometry.
