14PCV25-05-3 12.7 mm Dia. x -25 mm FL; Uncoated; Plano-Concave Lens
The 14PCV25-05-3 is a Plano-Concave Lens with a diameter of 12.7 mm and a focal length of -25 mm, making it a negatively powered lens. This lens is sourced from Standa, a reputable vendor in the optical industry, and is available for purchase on their website. The lens is uncoated, meaning it does not have any additional layers to protect or enhance its optical properties.
The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 4 mm, while the center thickness is 1.9 mm. The lens's inner and outer radii are both 0, indicating a simple, straightforward design. The lens's effective focal length (EFL) is -25 mm, which is the distance from the lens's principal point to the focal point.
The lens is made of CAF2 (Calcium Fluoride), a material with the Mal-1963 ID. This material is known for its excellent transparency in the infrared region, making it suitable for applications in this spectrum. The lens's wavelength is 2940 nm, further emphasizing its suitability for infrared applications.
