112-1117E 12.7 mm Dia. x -125 mm FL; Uncoated; Plano-Concave Lens
The 112-1117E is a Plano-Concave Lens, a type of spherical lens, sourced from EKSMA Optics. This lens has a diameter of 12.7 mm and a center thickness of 2.7 mm, with an edge thickness of 3 mm. The lens's effective focal length (EFL) is -125 mm, indicating its diverging nature. The concave surface of the lens has a radius of curvature (R1) of -59.4 mm.
The lens is made from UVFS Mal- 1965, a material specifically designed for use in the ultraviolet spectrum at a wavelength of 355 nm. This material ID ensures the lens's suitability for applications requiring ultraviolet transmission.
Notably, this lens does not have any coating, which means it is uncoated. While uncoated lenses can be more cost-effective, they may have higher surface reflections and lower transmission compared to coated lenses. However, the choice of coating depends on the specific application and requirements.
