BICX-FS04 12.7 mm Dia. x 20 mm FL; Uncoated; Double-Convex Lens
The BICX-FS04 is a high-precision double-convex lens, 12.7 mm in diameter and featuring a focal length of 20 mm. This lens is sourced from WTS Photonics, a reputable vendor in the optical industry. The lens is uncoated, making it suitable for applications where coating is not a requirement or may interfere with the desired optical properties.
The lens's geometry is characterized by its base shape, which is circular, and its spherical design. The edge thickness of the lens is 2 mm, while the center thickness is 4.36 mm. The effective focal length (EFL) is 20 mm, and the first radius of curvature (R1) is 17.7 mm, while the second radius (R2) is -17.7 mm. The back focal length (BFL) is 18.46 mm. The lens does not have an inner or outer radius.
The lens is made of fused silica (mal-1965), a material known for its high transparency and resistance to thermal shock. The lens is designed to operate at a wavelength of 546.1 nm.
This lens is ideal for applications that require a high-quality, double-convex lens with a long focal length. Its uncoated design makes it versatile, suitable for use in a wide range of optical systems.
