112-1227E 25.4 mm Dia. x -400 mm FL; Uncoated; Plano-Concave Lens
The 112-1227E is a Plano-Concave Lens, a type of spherical lens, sourced from EKSMA Optics. This lens is characterized by its concave shape, which is thicker at the edge and thinner at the center. The lens has a diameter of 25.4 mm and a center thickness of 3.6 mm, with the edge being slightly thicker at 4 mm.
The lens has an effective focal length (EFL) of -400 mm, indicating that it is a diverging lens, causing parallel rays to spread out. The radius of curvature (R1) is -190.2 mm, and the inner and outer radii are both 0 mm.
This lens is made from UVFS Mal-1965, a material specifically designed for use in the ultraviolet region of the spectrum. The wavelength of this lens is 355 nm, further emphasizing its use in ultraviolet applications.
Notably, this lens is uncoated, meaning it does not have any additional layers to enhance its durability or performance. While this may limit its use in certain applications, it can be beneficial in others, such as when minimal reflection is required.
