When a catalog optical window won't work in your design, Advanced Optics can help.  Our skilled team of professionals have over 50 years of experience crafting custom optical windows and can meet the requirements of your unique project.

We accomplish this by carefully listening to your specifications, providing attention to every detail and delivering a custom optical window that meets or exceeds your expectations. Whether you require a single prototype, production quantities or anything in between, our extensive stock of on-site raw materials allows us to meet your requirements for fast delivery with competitive prices.

Our optical customization capabilities allow us to:

  • Drill holes.
  • Produce beveled substrates.
  • Fabricate custom sizes and shapes.
  • Design and supply custom coatings
  • Modify and resurface customer supplied substrates
  • Precision polish up to λ/20 and hold parallelism of < 2 arc seconds.

Custom Optical Coatings

Does your project require a custom optical coating? Advanced Optics can provide custom anti-reflective coatings to meet your specific reflectivity requirements. Simply provide your wavelength(s) of interest, the % reflectivity you require, and the AOI you will be using and we will design the perfect coating for your application.

Need help correctly specifying a custom optical window?

Optical windows are transparent, optically flat substrates that separate two different environments while allowing light to pass through. They may be either parallel (used to minimize the distortion of a transmitted beam of light of a specific wavelength) or wedged (used to direct transmitted light at a particular angle and reduce back reflection) and come either uncoated or with an anti-reflective coating used to reduce reflectance and improve transmission.

To perform as expected, having a good understanding of your application (as well as specifying the correct optical characteristics) is essential to reducing costs and procuring the perfect window.

Careful consideration should be given to the following and provided when requesting an optical window.

Careful consideration of all 10 steps will help the manufacturer of your window clearly understand your requirements which translates to a faster and more accurate quotation.

Advanced Optics can also modify in-stock optical windows for fast turnaround. View our in-stock optical windows available for modification.
