114-1205E 25.4 mm Dia. x -30 mm FL; Uncoated; Double-Concave Lens
The 114-1205E is a spherical lens with a base shape of circle, designed and manufactured by EKSMA Optics. This lens falls under the category of a double-concave lens, featuring negative focal length, making it suitable for applications that require light convergence.
The lens has a diameter of 25.4 mm and a thickness of 7.5 mm at the edge, while the center thickness is 3 mm. The effective focal length (EFL) of this lens is -30 mm, indicating that it will diverge a collimated beam. The first radius of curvature (R1) is -29 mm, and the second radius of curvature (R2) is 29 mm, both of which are spherical.
This lens is made from UVFS MAL-1965 material, specifically designed for use at a wavelength of 355 nm. The lens does not come with any coating, which means it is uncoated. However, users can request custom coatings based on their specific requirements.
