112-0502E 50.8 mm Dia. x -75 mm FL; Uncoated; Plano-Concave Lens
The 112-0502E is a plano-concave lens with a diameter of 50.8 mm and a focal length of -75 mm, sourced from EKSMA Optics. This lens is a spherical type, designed with a base shape of a circle, and is uncoated.
The lens's geometry is defined by its diameter, thickness edge, and thickness center. The diameter measures 50.8 mm, while the thickness edge is 12 mm and the thickness center is 3 mm. The effective focal length (EFL) is -75 mm, and the radius of curvature (R1) is -38.9 mm. The inner and outer radii are both 0, indicating a plano surface.
The lens is made from the material n-bk7 schott and is designed to work optimally at a wavelength of 546 nm. The lack of coating suggests that this lens is intended for use in applications where coating is not necessary or desirable.
This lens is currently in stock and more information can be found on the EKSMA Optics website.
