The 110-5222E is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 300 mm. This lens is sourced from EKSMA Optics, a reputable vendor known for their high-quality optical components. The lens is made of CAF2 (MgF2) material, specifically the variant mal-1963, which is well-suited for various optical applications.
The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 3.1 mm, while the center thickness is slightly greater at 3.7 mm. The lens's effective focal length (EFL) is 300 mm, and it has a curvature radius (R1) of 125.5 mm. The lens's inner and outer radii are both zero, indicating a plano surface on one side and a convex surface on the other.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, its bare CAF2 material ensures excellent transparency and a high refractive index. The lens is designed to operate at a wavelength of 2940 nm, making it suitable for infrared applications.
