L-BCC014 12.5 mm Dia. Double-Concave Lens; EFL=-25mm Uncoated

The L-BCC014 is a 12.5 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical component vendor, Ross Optical. This lens is designed for use in a wide range of optical applications, thanks to its unique geometry and material composition.

The lens features a double-concave design, meaning it has two curved surfaces that both curve inward. This design is characterized by its EFL (Effective Focal Length) of -25mm, which is a measure of the lens's ability to focus light. The negative value indicates that this is a diverging lens, meaning it spreads out light rays, rather than converging them like a positive lens.

The lens is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties. This material is chosen for its low dispersion, high transmission, and high Abbe number, making it ideal for use in a wide range of applications, from imaging to laser systems.

The lens has a center thickness of 1.5mm and an edge thickness of 3.1mm, providing a good balance between durability and optical performance. The inner and outer radii of the lens are 0mm, indicating a symmetrical design.

Please note that this lens is uncoated. While uncoated lenses can be more cost-effective, they may be more susceptible to surface reflections and scratching. Coatings can be applied to reduce these issues, but they may also increase the cost and complexity of the lens.
