112-1109E 12.7 mm Dia. x -50 mm FL; Uncoated; Plano-Concave Lens
The 112-1109E 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 2.2 mm at the center.
The lens's focal length (FL) is -50 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 from UVFS MAL-1965 material, specifically designed for use with a wavelength of 355 nm. This makes it suitable for applications in the ultraviolet spectrum.
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 make the lens more susceptible to damage and may limit its performance in certain applications.
Despite this, the 112-1109E is a versatile lens, suitable for a wide range of optical systems. It is currently in stock and available for purchase, with more information available on the EKSMA Optics website.
