LPK-25.0-259.4-C 25 mm Dia. N-BK7 Image Grade Plano-Concave Lens; EFL=-500mm Uncoated
The LPK-25.0-259.4-C is a high-quality Plano-Concave Spherical Lens, offered by CVI Laser Optics. This lens, with a diameter of 25 mm, is designed for use in imaging systems and is fabricated from N-BK7 Schott glass, a material renowned for its excellent optical properties.
The lens's geometry is defined by its center thickness of 2 mm and a radius of curvature of -259.4 mm on the concave surface. The effective focal length (EFL) is -500 mm, indicating that this lens will diverge light. This makes it suitable for use in applications where a collimated beam needs to be expanded or where a point source needs to be imaged over a larger area.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means the lens is less susceptible to damage from environmental factors, making it suitable for use in harsh environments.
