114-1224E 25.4 mm Dia. x -200 mm FL; Uncoated; Double-Concave Lens
The 114-1224E is a high-quality double-concave lens, sourced from EKSMA Optics, a renowned vendor in the optical components industry. This lens is specifically designed for use in a wide range of optical applications, thanks to its unique geometry and material composition.
The lens features a base shape of a circle, with a diameter of 25.4 mm, making it suitable for use in systems with a moderate aperture. The double-concave design, characterized by its inner radius of 0 and outer radius of 0, provides a negative focal length of -200 mm. This makes it ideal for use in applications where light needs to be diverged or dispersed.
The lens has a thickness of 3.8 mm at the edge and 3 mm at the center, providing a robust structure while minimizing unnecessary weight. The material used for this lens is UVFS Mal-1965, a material well-known for its optical properties at the wavelength of 355 nm.
Notably, this lens is uncoated, offering a cost-effective solution for applications where coating is not a necessity. However, for applications where coating is required, EKSMA Optics offers a wide range of coating options that can be customized according to specific needs.
