112-5217E 25.4 mm Dia. x -150 mm FL; Uncoated; Plano-Concave Lens

The 112-5217E is a plano-concave lens with a diameter of 25.4 mm and a focal length of -150 mm, making it a negatively powered lens. This lens is sourced from EKSMA Optics, a reputable vendor in the optical components industry. The lens's geometry includes a thickness edge of 4 mm and a center thickness of 2.7 mm, providing a slim profile that can be beneficial in various applications.

The lens is made from CAF2 (Calcium Fluoride) material, specifically the Mal-1963 variant, which is known for its excellent transparency in the infrared region. This makes the lens suitable for applications that require transmission of light in this spectral range, such as infrared spectroscopy or thermal imaging.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This can be advantageous in applications where the introduction of additional layers might interfere with the desired optical performance. However, it's important to note that uncoated lenses can be more susceptible to surface contamination and damage, so they may require more careful handling and cleaning.

The provided item data does not include information about the lens's coating, wavelength, or shape. Therefore, these aspects cannot be detailed in the description. However, the data provided is comprehensive enough to provide a clear understanding of the lens's key features and specifications.
