Calcium fluoride plano-convex lens is a high-performance optical component designed for superior ultraviolet and infrared transmission, excellent thermal stability, and precise light focusing. Manufactured from high-purity CaF₂, 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 calcium fluoride plano-convex lens is an optical component made from calcium fluoride, offering a broad transmission range (180 nm to 8.0 μm), high damage threshold, low fluorescence, and high uniformity. These lenses are ideal for laser collimation and as substrates for optical components. The lens can focus light to a single point and is commonly used in laser systems and beam shaping applications. Due to the softer nature of calcium fluoride, the lens surface can be scratched easily, so careful handling is necessary.
