The optical module for openQMCM NEXT allows the optical access to the sensor surface. Thanks to the embedded SiO2 window, it is possible to combine the QCM technique with optical/spectral analyses (e.g.: UV, Raman, etc.).
In order to avoid chemical contaminations, the optical window is embedded to its top cover by meand a thin PTFE frame.
Thanks to this solution it was possible to avoid the use of glues or other chemical substances.
The module consists of:
- 1 chromed Aluminum base, with an integrated proximity electronics, that mounts a 10K thermistor for an active T-control feedback;
- 1 electroplated Nickel Stainless steel top cover that includes a central quartz window and an engraved viton o-ring holder for sealing the internal chamber;
- 2 M2.5 slotted Round Nuts (DIN 546) - Marine Stainless Steel (A4)
