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 75mm, which is the distance from the lens's center to the focal point.
The lens's geometry includes a thickness of 2mm at the edge and 4.5mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, 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 33.87mm.
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 protection or enhancement features, such as anti-reflective coatings or scratch-resistant surfaces.
