Description
Discover our comprehensive range of optical materials designed for precision and performance across various wavelengths. Our selection includes materials such as **ZnSe**, **ZnS**, **Ge**, **Silicon**, **CaF2**, **Sapphire**, **Fused Silica**, **SF**, and **BK7**, each meticulously crafted to meet stringent specifications. Whether you require spherical lenses, cylindrical lenses, or flat/plano surfaces, our materials offer exceptional quality and reliability.
Each optical component is engineered with a diameter tolerance of +0.0''/-0.010'' and a thickness tolerance of ±0.010''. The wedge surface figure is maintained at less than 3 arc minutes, ensuring high precision. With a surface quality of 40/20 or better, these materials provide an outstanding transmission rate of over 85%, making them ideal for a wide range of optical applications.
Our product line is optimized for performance in specific wavelength ranges. For infrared applications, we offer narrowband and broadband options covering 2µm to 20µm, with reflection rates (R) as low as ≤0.5% at normal incidence and ≤1.0% at 45°. For UV/VIS/NIR applications, our narrowband products range from 222nm to 2.0µm, with exceptionally low reflection rates of ≤0.25% at normal incidence and ≤0.5% at 45°. Our laserline coatings provide superior reflectance, achieving R ≥ 99.5% for IR and R ≥ 99.7% for UV/VIS/NIR, ensuring minimal loss and maximum efficiency.
Please note that these specifications serve as a general reference and may vary based on dimensions and specific customer requirements. Our team is committed to delivering customized solutions to meet your unique optical needs, ensuring that each product meets the highest standards of quality and performance.
