Optical module for openQCM NEXT

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 the PTFE core.
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 PTFE core slotted in an aluminim anodized shell;
• 1 embedded SiO2 window (diameter: 7 mm - thickness: 3mm)
• 1 external aluminium anodized shell;
• 1 KFM (Viton) o-ring
