112-5205E 25.4 mm Dia. x -50 mm FL; Uncoated; Plano-Concave Lens

The 112-5205E is a Plano-Concave Lens with a diameter of 25.4 mm and a focal length of -50 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 7 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 of the spectrum. This makes the lens suitable for applications that require transmission of light in this 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 coating might introduce unwanted reflections or interfere with the optical path. However, it's essential to consider that uncoated lenses can be more susceptible to dirt, dust, and scratches, which can affect their performance over time.

Please note that the lens's inner and outer radii are both zero, indicating a simple plano-concave shape. The wavelength for this lens is 2940 nm, which is in the infrared spectrum. This information, along with the lens's other specifications, can be crucial in determining its suitability for specific applications.
