Product Description
The Calcium Fluoride (CaF₂) Plano-Convex Lens is fabricated from high-purity crystalline CaF₂ material, known for its outstanding transmittance from 180 nm to 8 μm. Its low refractive index and minimal chromatic aberration make it a preferred choice for broadband optical systems. The plano-convex design enables effective light focusing with minimal spherical aberration. With excellent resistance to moisture, thermal shock, and high laser energy, this lens is widely used in laser focusing, spectroscopy, and infrared imaging. Customized coatings and dimensions are available to meet specific optical requirements.
