BICV204 25.4 mm Dia. x -50 mm FL; Uncoated; Double-Concave Lens

The BICV204 is a high-precision double-concave lens, 25.4 mm in diameter, offered by WTS Photonics. This lens is designed with a base shape of a circle and features a double-concave structure, making it suitable for a variety of applications.

The lens has a center thickness of 2 mm and an edge thickness of 5.22 mm, providing a robust structure while maintaining a sleek profile. The effective focal length (EFL) is -50 mm, indicating that it is a diverging lens, which spreads out light rays that pass through it.

The BICV204 is made from n-BK7 Schott glass, a popular material for optical lenses due to its excellent optical properties and durability. The radii of curvature for the first and second surfaces are -50.93 mm and 50.93 mm, respectively, contributing to the lens's double-concave design.

The back focal length (BFL) of this lens is 48.22 mm, which is the distance from the rear surface of the lens to the focal point. The lens does not have any coating, which means it is uncoated, but it can be customized upon request.

This lens is designed to work with a wavelength of 546.1 nm, making it suitable for applications that use this specific wavelength. The lens is currently in stock and available for immediate purchase from the WTS Photonics website.
