110-5123E 12.7 mm Dia. x 200 mm FL; Uncoated; Plano-Convex Lens
The 110-5123E is a plano-convex lens with a diameter of 12.7 mm and a focal length of 200 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 Mal-1963 variant, which is well-suited for various applications due to its excellent optical properties.
The lens's geometry is characterized by its plano-convex shape, where one side is flat, and the other side is curved. The thickness at the edge of the lens is 2 mm, while the center thickness is slightly greater at 2.2 mm. The lens's inner and outer radii are both zero, indicating a sharply curved convex surface.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While coatings can be beneficial in reducing reflection and increasing transmission, an uncoated lens can be suitable for applications where such enhancements are not necessary.
The lens is designed to operate at a wavelength of 2940 nm. This makes it suitable for applications that use this specific wavelength, such as certain types of spectroscopy or laser applications.
