Optical Windows

Photonway Technology supplies a range of custom precision grade large optical windows and micro windows that are designed to minimize both reflection and absorption while maximizing transmission over a target wavelength range.

We provide a wide selection of substrates to suit your specific needs. To increases durability and efficiency, most of our windows are coated with an anti-reflective coating, ranging for the Ultraviolet (UV), Visible, or Infrared (IR).

These flat windows feature highly polished surfaces. While flatness of 1λ is sufficient for most commercial quality applications, we also supply flatness options of λ/4, λ/10, and λ/20 for use in applications where precision is at a premium.

We take pride in our reliable polishing technique, each optical flats are carefully tested with precision metrology equipment to ensure they fully meet the flatness level & surface quality specified by customer.

Inspection report will be provided along with shipment.
