The 88-168 is a Plano-Convex (PCX) lens with a diameter of 50mm and a focal length of 100mm, making it ideal for a wide range of optical applications. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made of Calcium Fluoride (CaF2), a material with a high transmission range spanning from the ultraviolet to the infrared regions of the spectrum. This particular lens is designed for use at a wavelength of 266nm, making it suitable for applications such as laser systems and UV spectroscopy.
The geometry of the lens includes an edge thickness of 1.65mm and a center thickness of 9mm. The lens's inner and outer radii are both zero, indicating a flat surface on one side and a curved surface on the other. The radius of curvature (R1) of the curved surface is 46.21mm, and the back focal length (BFL) is 93.85mm.
Notably, this lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and increased susceptibility to environmental factors, it can also reduce surface reflections and improve overall system efficiency in certain applications.
