112-5225E 25.4 mm Dia. x -300 mm FL; Uncoated; Plano-Concave Lens
The 112-5225E is a Plano-Concave Lens, a type of spherical lens, sourced from EKSMA Optics. This lens is characterized by its concave shape, which is designed to diverge light rays. The lens has a diameter of 25.4 mm and a center thickness of 3.4 mm, with the edge being slightly thicker at 4 mm.
The effective focal length (EFL) of this lens is -300 mm, indicating that it is a negative or diverging lens. The radius of curvature (R1) is -125.5 mm, which is the radius of the curved surface of the lens. The inner and outer radii are both 0, suggesting that the lens has a uniform thickness.
This lens is made from CAF2 (Calcium Fluoride), a material with the Mal-1963 designation. It is specifically designed for use with a wavelength of 2940 nm. The lens does not come with any coating, which means it is uncoated.
The lens is currently in stock and more information about it can be found on the EKSMA Optics website. This lens is suitable for various applications that require light divergence, such as in imaging systems, beam shaping, and other optical setups.
