Saving Time & Money with Crystran’s Stock Optics & Re-polishing Service
The application of a thin-film / dielectric coating on an optical surface is a complicated process. To ensure coating performance meets design expectation, both spectrally and environmentally, small (typically 25x1 mm) ‘witness pieces’ are routinely included in every furnace run.
At Crystran, we’re happy to work with coating companies to essentially recycle their old / used witness pieces, saving them both time and money. We have a huge amount of in-house expertise polishing a wide variety of UV / VIS / IR materials, and can easily remove an ‘old’ coating and make the window as good as new.
