114-0212E 25.4 mm Dia. x -75 mm FL; Uncoated; Double-Concave Lens

The 114-0212E is a double-concave spherical lens, sourced from EKSMA Optics, with a base shape of a circle. This lens is designed for use in various optical systems, offering a -75 mm focal length (FL) and a 25.4 mm diameter. The lens's geometry includes an edge thickness of 5.5 mm and a center thickness of 3.7 mm, contributing to its overall robustness and functionality.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties, including a high Abbe number and low dispersion. The wavelength for this lens is 546 nm. The double-concave design, with radii of curvature of -78.4 mm and 78.4 mm, allows for effective light bending and focusing within optical systems.

Notably, this lens does not come with any coating, which means it is uncoated. While coatings can enhance the performance of lenses by reducing reflection, increasing transmission, or providing other benefits, an uncoated lens can be suitable for certain applications where such enhancements are not required.
