BICX308 38 mm Dia. x 350 mm FL; Uncoated; Double-Convex Lens

The BICX308 is a high-precision, double-convex lens offered by WTS Photonics. This lens boasts a diameter of 38 mm and a focal length of 350 mm, making it suitable for a wide range of optical applications. The lens is uncoated, providing a clear, unaltered view of the light path.

The lens features a base shape of a circle, with a thickness of 3 mm at the edge and 4 mm at the center. The effective focal length (EFL) is 350 mm, while the back focal length (BFL) is 348.66 mm. The radii of curvature are 362.4 mm for the first surface and -362.4 mm for the second surface, indicating a convex-convex or biconvex design.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. The lens is designed to operate at a wavelength of 546.1 nm. The geometry of the lens is spherical, ensuring a uniform and consistent light path.

This lens is ideal for applications that require a clear, undistorted image, such as imaging systems, beam shaping, and laser applications. The double-convex design provides a wide field of view and low spherical aberration, making it a versatile choice for many optical setups.

Please note that the lens is uncoated, which means it does not have any anti-reflective or protective coatings. This may result in some light loss due to reflection at the air-glass interfaces. However, the uncoated surface can be beneficial in certain applications where a specific reflection coefficient is required.
