112-5120E 12.7 mm Dia. x -150 mm FL; Uncoated; Plano-Concave Lens
The 112-5120E is a Plano-Concave Lens, a type of spherical lens, sourced from EKSMA Optics. This lens is characterized by its circular base shape and uncoated surface. The lens has a diameter of 12.7 mm and a thickness that varies from 3 mm at the edge to 2.7 mm at the center.
The lens's focal length (FL) is -150 mm, indicating that it is a diverging lens, causing light rays to spread out after passing through it. The inner radius of the lens is 0 mm, and the outer radius is also 0 mm, which is typical for a plano-concave lens.
The lens is made of CAF2 (Calcium Fluoride) material, specifically the mal-1963 variant. It is designed to work with a wavelength of 2940 nm. This lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website provided in the weblinks section.
