BICX211 25.4 mm Dia. x 250 mm FL; Uncoated; Double-Convex Lens

The BICX211 is a high-precision double-convex lens, 25.4 mm in diameter and 250 mm in focal length, sourced from WTS Photonics. This lens, designed for general-purpose use, is uncoated and features a double-convex spherical shape, making it suitable for a wide range of optical applications.

The lens's geometry is defined by a diameter of 25.4 mm, an edge thickness of 2 mm, and a center thickness of 2.62 mm. The effective focal length (EFL) is 250 mm, and the radii of curvature are r1 = 258.9 mm and r2 = -258.9 mm. The back focal length (BFL) is 249.12 mm, and both the inner and outer radii are 0 mm.

The lens is made of n-BK7 Schott, a high-grade optical glass known for its excellent transparency and low auto-fluorescence. The material is designed to provide optimal performance in the visible light spectrum, with a central wavelength of 546.1 nm.

Please note that this lens is uncoated, which may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors. However, the uncoated surface can be advantageous in applications where anti-reflection coatings are not desired or necessary.
