Optical Thin Film Coatings



Pyser-SGI now offer a complete optical thin film coatings service, from single layer to multi layer A/R coatings to dichroic, mirror and band-pass filter coatings. Using Essential Macleod software, a variety of coating processes and Spectrometer instruments we can guarantee the quality of the finished coating.

We can test the spectral response of the finished product in reflection, absorbance and transmission modes from 200 to 3200nm.

Our modern coating plants all have in-process ionic cleaning and thickness monitoring. Our cold vacuum deposition allows us to coat high performance anti-reflective films and many other coatings onto cemented and painted components.
