BICX401 40 mm Dia. x 63.5 mm FL; Uncoated; Double-Convex Lens

The BICX401 is a high-precision double-convex lens, 40 mm in diameter and 63.5 mm in focal length, sourced from WTS Photonics. This lens is uncoated and features a double-convex design, making it suitable for a wide range of optical applications.

The lens's geometry is characterized by a diameter of 40 mm, a thickness at the edge of 1.9 mm, and a thickness at the center of 8.27 mm. The effective focal length (EFL) is 64 mm, while the radius of curvature for the first surface (R1) is 64.42 mm and -64.42 mm for the second surface (R2). The back focal length (BFL) is 60.7 mm. The lens does not have an inner or outer radius.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The lens is designed to work at a wavelength of 546.1 nm. The shape of the lens is spherical, a common choice for its ease of manufacturing and versatility.

Please note that the lens is uncoated, which may affect its performance in certain applications, particularly those involving high-intensity light sources or extreme environmental conditions. However, uncoated lenses can be advantageous in applications where cost, simplicity, or specific optical characteristics are primary concerns.
