LC1093 N-BK7 Plano-Concave Lens; Dia:2 in; f=-100.0 mm Uncoated

The LC1093 N-BK7 Plano-Concave Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of precision photonics. This lens, with a diameter of 2 inches, is designed for use in a variety of optical systems, offering a focal length of -100.0 mm for precise focusing capabilities.

The lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material, also known as Schott glass, is characterized by a high refractive index and low dispersion, making it ideal for a wide range of applications. The plano-concave design of the lens, where one surface is flat and the other is curved, allows for the controlled bending of light rays, making it suitable for use in beam shaping, collimation, and focusing applications.

The lens has a diameter of 50.8 mm and a thickness at the edge of 10.7 mm. The center thickness is 4 mm, providing a robust and stable platform for optical systems. The effective focal length (EFL) of -100 mm is a key parameter, determining the lens's focusing power. The radius of curvature (R1) is -51.5 mm, and the back focal length (BFL) is -102.6 mm, both of which contribute to the lens's optical performance.

The lens does not come with any coating, as indicated in the item data. However, various coatings can be applied to enhance the lens's performance, such as anti-reflective coatings to reduce surface reflections or protective coatings to increase durability.
