BICC-12.7/100.0C 12.7 mm Dia. x -97 mm FL; Uncoated; Double-Concave Lens

This is a double-concave lens, also known as a biconcave lens, sourced from the renowned optical components vendor, Laser Components. The lens is characterized by its concave-concave base shape and circular geometry, with a diameter of 12.7 mm and a thickness that varies from 2 mm at the center to 2.4 mm at the edge.

The lens is designed with an effective focal length (EFL) of -97 mm, indicating that it is a diverging lens, causing incoming light rays to spread out after passing through it. The radii of curvature for the first and second surfaces are -100 mm and 100 mm, respectively. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.

This lens is intended for use with a wavelength of 633 nm. Notably, the lens does not have any coating, which means it is uncoated. While uncoated lenses can be sufficient for certain applications, coatings are often applied to enhance the lens's performance, such as reducing surface reflections, increasing transmission, or providing scratch resistance.
