112-0419E 38.1 mm Dia. x -300 mm FL; Uncoated; Plano-Concave Lens
The 112-0419E is a Plano-Concave Lens with a diameter of 38.1 mm and a focal length of -300 mm. This lens is sourced from EKSMA Optics, a renowned vendor in the optical components industry. The lens is designed with a spherical shape, featuring a base shape that is circular.
The lens's geometry includes a thickness edge of 5.8 mm and a thickness center of 4.7 mm. The effective focal length (EFL) is -300 mm, and the radius of curvature (R1) is -155.6 mm. The lens does not have an inner or outer radius, indicating a plano surface.
The lens is made from the material n-bk7 schott, a popular choice for optical applications due to its excellent optical properties. The wavelength for this lens is 546 nm.
Notably, this lens does not have any coating, which means it is uncoated. This may affect the lens's performance in certain applications, particularly those requiring high transmission or specific surface properties. However, uncoated lenses can be more cost-effective and are suitable for applications where coating is not a critical factor.
