LC1054 N-BK7 Plano-Concave Lens; Dia:0.5 in; f=-25.0 mm Uncoated

The LC1054 N-BK7 Plano-Concave Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 0.5 inches, is designed for use in a variety of optical systems, offering a focal length of -25.0 mm for precise focusing and image formation.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material, also known as Schott glass, is widely used in optical systems due to its low dispersion and high transmission across a broad spectrum of wavelengths. The lens's geometry includes a plano-concave shape, where one surface is flat, and the other is curved inward, contributing to its negative focal length.

The lens has a diameter of 12.7 mm, with an edge thickness of 4.7 mm and a center thickness of 3 mm. The back focal length (BFL) is -27 mm, and the effective focal length (EFL) is -25 mm. The inner and outer radii are 0 mm, indicating a symmetrical curvature.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While coatings can be beneficial in reducing reflection, increasing transmission, and protecting the lens surface, an uncoated lens can be suitable for many applications where such enhancements are not required.
