L-BCC004 6 mm Dia. Double-Concave Lens; EFL=-8mm Uncoated

The L-BCC004 is a 6 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical component vendor, Ross Optical. This lens boasts an effective focal length (EFL) of -8mm, making it suitable for applications that require strong negative optical power.

The lens is fabricated from the high-quality material, N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including low dispersion and high homogeneity. This material is widely used in various optical systems, such as cameras, microscopes, and beam delivery systems.

The lens geometry features a double-concave design, with radii of curvature R1 and R2 measured at -8.736397611mm and 8.736397611mm, respectively. The center thickness of the lens is 2mm, while the edge thickness is 2.9mm, providing robustness and durability.

The lens is uncoated, offering bare glass surfaces. While coatings can enhance the performance of lenses by reducing surface reflections, increasing transmission, and providing protection against environmental factors, uncoated lenses can be advantageous in certain applications due to their lower cost and simpler manufacturing process.
