112-5209E 25.4 mm Dia. x -75 mm FL; Uncoated; Plano-Concave Lens

The 112-5209E is a plano-concave lens with a diameter of 25.4 mm and a focal length of -75 mm, making it a negatively powered lens. This lens is sourced from EKSMA Optics, a reputable vendor known for its high-quality optical components.

The lens is spherical in shape, meaning it has a smoothly curved surface that refracts light evenly across its surface. The base shape is circular, which is a common feature in lenses used in various optical applications.

The geometry of the lens includes a thickness edge of 5.5 mm and a thickness center of 2.8 mm. The inner and outer radii are both zero, indicating a simple concave shape. The lens is made from CAF2 (Calcium Fluoride), a material with the Mal-1963 designation, and is optimized for a wavelength of 2940 nm.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other desirable optical properties. However, this lens is in its bare form, allowing users to apply their preferred coatings based on their specific requirements.

The lens is currently in stock and available for immediate use. For more information, including pricing and availability, users are encouraged to visit the vendor's website using the provided weblink.
