Description
Our premium selection of optical materials is crafted to meet the highest standards of precision and quality, offering exceptional performance across a wide range of applications. Each material is meticulously manufactured to ensure a diameter tolerance of +0.0''/-.010'' and a thickness tolerance of ±.010''. This precise engineering guarantees that our products deliver reliable and consistent results, no matter the complexity of your optical system.
Featuring an outstanding wedge surface figure of less than 3 arc minutes and a surface quality of 40/20 or better, these materials provide superior optical clarity and minimal distortion. The impressive surface flatness of λ/40 at 10.6µm for infrared wavelengths further enhances their performance. With a surface quality exceeding 85%, you can trust in the exceptional light transmission and minimal scattering offered by these optical components.
Our collection includes a variety of materials such as ZnSe, ZnS, Ge, Silicon, CaF2, Sapphire, Fused Silica, SF, and BK7. Each material is designed to cater to specific wavelength ranges and is available with a CA chamfer of .01'' to .03'' at 45°, ensuring a perfect fit for your optical assembly. Whether you require spherical lenses, cylindrical lenses, or flats/plano surfaces, our products are engineered to meet your precise specifications.
For specialized applications, our coatings offer narrowband and broadband options across infrared (IR), ultraviolet (UV), visible (VIS), and near-infrared (NIR) spectra. These coatings deliver exceptional anti-reflective properties, with reflectance values as low as R ≤ 0.25% for narrowband UV/VIS/NIR and R ≤ 0.5% for broadband VIS/NIR. Laserline coatings are also available, providing reflectance levels of R ≥ 99.5% in IR and R ≥ 99.7% in UV/VIS/NIR, ensuring optimal performance for laser applications.
Please note that the specifications provided are intended for reference only and may vary based on dimensions and specific customer requirements. Our commitment to quality and precision ensures that each optical component is tailored to meet the unique demands of your project.
