LPK-12.5-25.9-C 12.5 mm Dia. N-BK7 Image Grade Plano-Concave Lens; EFL=-50mm Uncoated
The LPK-12.5-25.9-C is a high-quality Plano-Concave Spherical Lens, offered by CVI Laser Optics. This lens, with a diameter of 12.5 mm, is designed for use in imaging systems and is crafted from N-BK7 Schott glass, a material known for its excellent optical properties.
The lens's geometry is characterized by its center thickness of 2 mm and an effective focal length (EFL) of -50 mm, making it suitable for applications requiring negative focal lengths. The concave surface of the lens has a radius of curvature of -25.9 mm. The lens's inner and outer radii are both 0, indicating a uniform curvature across the lens surface.
This lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While coatings can enhance performance in certain applications, an uncoated lens can be advantageous in situations where cost, simplicity, or specific optical characteristics are priorities.
