The 112-1119E 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 effective focal length (EFL) of this lens is -150 mm, indicating that it is a diverging lens, causing incoming light rays to spread out.
The lens is made from UVFS MAL-1965, a material with a refractive index that determines how much light is bent when it passes through the lens. The wavelength of operation for this lens is 355 nm.
Notably, this lens does not have any coating, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
