Optical Windows

Optical windows are precision-crafted, optically flat, and transparent components designed to allow light to pass into an instrument while protecting its internal elements. At MOK Optics, we provide a wide range of optical windows tailored to meet the needs of various applications, from common usage to highly demanding interferometer measurements.

Features and Applications Of Optical Windows

  1. Material Selection: Our optical windows are made from a diverse selection of high-quality materials, including BK7, fused silica, sapphire, and other specialized glasses. Each material is chosen based on its unique properties, such as high transmission, low scattering, and resistance to environmental factors.
  2. Precision Engineering: We ensure each optical window meets stringent optical and mechanical specifications. Our windows are designed to offer superior flatness, parallelism, and surface quality, ensuring minimal distortion and high performance in critical applications.
  3. Coatings: To enhance performance, our optical windows can be customized with various anti-reflective (AR) coatings, dielectric coatings, and metallic coatings. These coatings improve transmission, reduce reflection losses, and provide additional durability against harsh environments.
  4. Customization Options: Beyond standard offerings, we provide bespoke solutions tailored to specific customer requirements. Whether you need special shapes, sizes, or unique material combinations, our experienced engineers are ready to collaborate and deliver customized optical windows that fit your exact needs.
  5. Applications:
    • Scientific Research: Used in laboratories for precise measurements and experiments.
    • Industrial Use: Applied in machinery and equipment where clear visibility and protection from contaminants are crucial.
    • Aerospace and Defense: Essential for optical systems in harsh environments, ensuring reliability and performance under extreme conditions.
    • Medical Instruments: Utilized in devices requiring high optical clarity and minimal distortion for accurate diagnostics and treatment.
