LPK-12.5-13.0-C 12.5 mm Dia. N-BK7 Image Grade Plano-Concave Lens; EFL=-25mm Uncoated
The LPK-12.5-13.0-C is a high-quality Plano-Concave Spherical Lens, sourced from 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 well-known for its excellent optical properties.
The lens's geometry is defined by its center thickness of 2 mm and an effective focal length (EFL) of -25 mm, indicating its concave shape. The inner radius is 0 mm, and the outer radius is also 0 mm, suggesting a symmetrical design. The lens's concave shape is further specified by a radius of curvature (R1) of -13 mm.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, it is still suitable for many applications, especially where cost-effectiveness is a priority. The lens is designed to operate at a wavelength of 546.1 nm, making it suitable for use in a wide range of optical systems.
