The 36-709 is a UV-VIS coated plano-convex lens, boasting a diameter of 12mm and a focal length of 84mm. This lens, sourced from Edmund Optics, is designed for use within the ultraviolet to visible light spectrum, spanning from 250 to 700nm.
The lens's geometry is characterized by a thickness of 2.03mm at the edge, increasing to 2.5mm at the center. The effective focal length (EFL) is 84mm, with a front radius (R1) of 38.51mm. The back focal length (BFL) measures 82.28mm, while the inner and outer radii are both 0mm, indicating a purely convex surface.
The lens is constructed from fused silica, identified as mal-1965 in the Material ID. This material is known for its excellent transparency and resistance to thermal shock, making it suitable for a wide range of optical applications.
The lens features a standard UV-VIS coating on both the front and back surfaces, adhering to Edmund Optics' standard curve. This coating enhances the lens's performance within the UV-VIS spectrum, reducing surface reflections and improving transmission.
