LPK-12.5-10.4-C 12.5 mm Dia. N-BK7 Image Grade Plano-Concave Lens; EFL=-20mm Uncoated

The LPK-12.5-10.4-C is a high-quality Plano-Concave Spherical Lens, offered by CVI Laser Optics. This lens, with a catalog number LPK-12.5-10.4-C, is designed for use in various optical applications, thanks to its superior image grade N-BK7 Schott material and uncoated finish.

The lens boasts a diameter of 12.5 mm, making it suitable for use in compact optical systems. The center thickness of the lens is 2 mm, providing a balance between optical performance and mechanical durability. The effective focal length (EFL) of this lens is -20 mm, indicating its concave nature, which is ideal for diverging light paths.

The lens is made from N-BK7 Schott glass, a material known for its excellent optical properties, including high homogeneity and low auto-fluorescence. This makes the lens suitable for applications that require high-precision optics, such as imaging, beam shaping, and laser systems.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. While this may result in a slightly lower transmission rate compared to coated lenses, it ensures a broader wavelength range compatibility, making it suitable for use with a wide range of light sources.

The lens data is available for download from the CVI Laser Optics website, providing users with detailed specifications for further analysis and design considerations. The lens is currently in stock, ensuring quick delivery and minimal lead times.
