110-5204E 25.4 mm Dia. x 40 mm FL; Uncoated; Plano-Convex Lens

The 110-5204E is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 40 mm. This lens is sourced from EKSMA Optics, a reputable vendor known for its high-quality optical components. The lens is made of CAF2 (MgF2) material, specifically the Mal-1963 variant, which is renowned for its excellent optical properties.

The lens's geometry is characterized by its edge thickness of 2.1 mm and center thickness of 7.9 mm. The inner and outer radii are both zero, indicating a plano-convex shape. The effective focal length (EFL) is 40 mm, which is the distance from the lens's principal point to the focal point. The lens's shape is spherical, which is a common feature in optical lenses due to its ease of manufacturing and good optical performance.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance the performance of a lens by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be a suitable choice for certain applications where such enhancements are not required.

The lens's wavelength is 2940 nm, which is in the infrared region of the electromagnetic spectrum. This makes the lens suitable for applications that use infrared light, such as thermal imaging, spectroscopy, or other infrared-based technologies.
