Who are we?

Welcome on the website of OPO, manufacturer of reflectometers and scatterometers for the monitoring of telescope's mirror coatings.
Our reflectometers / scatterometers CT7 and CT7a are benchmarks in the field, they are the improved successors of the highly regarded Iris Instrument. All these instruments were conceived and developed by Dr Sc Daniel Malaise konzipiert und entwickelt. For those with a good memory, OPO was previously known as DMO Optical Solutions.
We are a small research and development workshop exclusevely specialized in producing the most accurate reflectometers and scatterometers for the quality monitoring of telescope mirror's coatings.

We updated our products page to showcase the whole range of our offer. The last developments are the CT3 and CT3r, which are simplified 3 band industry versions of our main instrument, with or without the scatterometer.
We hope that you can easily find all the information you need on this website. Feel free to contact us directly if you have any question or interest. If you are a CT7 user already, you can access the Support section with your credentials.
