Optical Windows

Optical Windows

Our optical windows are designed for laser specific applications from 193 – 3000 nm. ARO optimizes for transmission, scatter, damage thresholds, and durability. Fused silica, CaF2, and other glass materials with diameters up to 17 inches are used.

Custom Optical Windows

Our technical team will review your optical drawing or custom specifications and provide an estimate. Typically we offer:

  • Size: 3 to 400 mm
  • Surface roughness: 3Ǻ
  • Anti-reflective coating, R < 0.25%
  • Surface quality: 10/5 Laser Quality (scratch/dig)
  • Parallelism: 1 minute
  • Surface flatness: we routinely provide 1/10λ Peak to Valley at 632.8nm, with the ability to achieve 1/20λ Peak to Valley
  • Standard tolerances include +0/-0.005″ for diameter, length or width and ± 0.005″ for thickness
    • (alternate specifications/tolerances available upon request)

    Performance Window Optics

    ARO delivers the top performance optical window from the deep ultraviolet to near infrared wavelength spectrums. We routinely work with fused silica, optical glasses, and crystalline substrate materials such as CaF2 and MgF2. All this while producing laser line windows in a wide range of sizes and geometric shapes. We utilize a variety of coating techniques to achieve the optimum thin film for each specific application. Coatings are optimized to transmit desired wavelengths and reflect all undesired wavelengths. ARO can use IBS and Magnetron Sputtering coating technologies to meet stringent environmental conditions.

    Laser Windows

    We have particular expertise in producing the following high transmission optics:

    • Solid state laser windows specifically designed to deliver high peak power damage threshold and low scatter, without sacrificing mechanical durability.
    • Excimer laser windows that provide excellent mechanical durability, pulse count lifetime, and high transmission, even at deep UV wavelengths.
    • Ultrafast laser windows that possess the optimum combination of broad spectral bandwidth, minimum group delay dispersion (GDD), low scatter, and peak pulse power damage resistance.

    Optical Window Manufacturer

    An optical window is flat transparent substrates with the maximum transmission in the specified wavelength ranges. Most often, optical windows are used as protective barriers for especially sensitive sensors and optical systems from the external environment. In the selection of optical windows, it is crucially important to choose the right substrate material. Alpine Research Optics is engaged in the creation of optical windows such as visible, interferometry, Near-IR Windows, Laser Line Windows, and UV Windows.

    Alpine Research Optics provides the knowledge and capabilities to manufacture optical windows for specific industries. We manufacture optical windows on a variety of substrates such as fused silica, CaF2, and other optical glasses. For over 30 years, we have been manufacturing optical equipment that is custom made to the scope of your application. When you work with us, you do not have to worry about the quality of the final product because we make each product to the top standards. We have experienced workforce and use the latest technologies, so products are consistently reliable. Every new product is quality tested to ensure the part meets all specifications. Regardless of window size or type, you can be sure that Alpine Research Optics will work tirelessly to create the perfect product for your project.
