BICX201 25.4 mm Dia. x 25 mm FL; Uncoated; Double-Convex Lens
The BICX201 is a high-precision double-convex lens, sourced from WTS Photonics, with a diameter of 25.4 mm and a focal length of 25 mm. This lens is uncoated and features a base shape of a circle, making it suitable for a wide range of optical applications.
The lens's geometry includes an edge thickness of 2 mm and a center thickness of 9.02 mm, providing a robust structure while maintaining a relatively thin profile. The effective focal length (EFL) is 25 mm, and the radii of curvature are R1 = 24.72 mm and R2 = -24.72 mm, indicating a symmetrical, double-convex design. The back focal length (BFL) is 22.24 mm, which is the distance between the lens's rear surface and the focal point.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The wavelength for this lens is 546.1 nm. The shape of the lens is spherical, which is the most common type of lens and offers a wide range of uses.
