112-1215E 25.4 mm Dia. x -125 mm FL; Uncoated; Plano-Concave Lens
The 112-1215E 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 25.4 mm and a thickness at the edge of 4.4 mm, while the center thickness is 3 mm. The effective focal length (EFL) of this lens is -125 mm, indicating its diverging nature.
The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, which is typical for plano-concave lenses. The concave surface of the lens has a radius of curvature (R1) of -59.4 mm. This lens is made from UVFS Mal- 1965 material, optimized for use at a wavelength of 355 nm.
The lens is uncoated, which means it does not have any additional layers to alter its optical properties. This can be beneficial in certain applications where the natural properties of the material are desired. However, it may also mean that the lens is more susceptible to environmental factors such as dust, dirt, and moisture.
This lens is currently in stock and more information about it can be found on the EKSMA Optics website.
