Lithium fluoride plano-convex lens is a high-performance optical component designed for superior ultraviolet and infrared transmission, exceptional thermal stability, and precise light focusing. Manufactured from high-purity LiF, it offers outstanding optical clarity, minimal distortion, and strong resistance to environmental degradation. This lens is widely used in laser systems, spectroscopy, aerospace applications, and precision scientific instruments, ensuring optimal optical performance for advanced imaging and beam-shaping applications.
Product Overview
The lithium fluoride plano-convex lens is an optical component made from lithium fluoride crystal material, designed with one flat surface and one convex surface. It offers excellent optical performance, especially for shaping and resizing light beams. Lithium fluoride has a wide transmission range (110 to 6,600 nm) and high transmittance, particularly in the infrared range (especially in the mid to long-wave infrared, such as 3–5 μm and 8–14 μm). This makes it ideal for applications in infrared lasers, infrared night vision devices, and other infrared systems. The lithium fluoride plano-convex lens is commonly used for beam collimation, focusing, beam expansion, and imaging in optical systems.
