LPK-25.0-25.9-C 25 mm Dia. N-BK7 Image Grade Plano-Concave Lens; EFL=-50mm Uncoated

The LPK-25.0-25.9-C is a high-quality Plano-Concave Spherical Lens, boasting a 25 mm diameter and a center thickness of 2 mm. This lens is crafted from N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and versatility. The lens is uncoated, offering a cost-effective solution for applications where anti-reflective coatings are not required.

The lens's effective focal length (EFL) is -50 mm, indicating its concave nature. This negative focal length is ideal for use in applications such as beam expansion, collimation, or image reduction. The lens's inner and outer radii are both zero, suggesting a symmetrical design, which can contribute to improved image quality and reduced aberrations.
