MProbe In-Situ measurement system: Real-time optical thickness monitor



Real-time broadband optical thickness monitor.
Special model – MProbe UVVisF – for measurement in high ambient light environment e.g. sputtering or other plasma assisted deposition techniques. Use of high-intensity flush Xe lamp with gated data acquisition, allows accurate measurement in most challenging environment.
Flexible integration: reflectance probe can be placed outside the deposition chamber optical port or inside, using a fiberoptics feedthru. Light can be focused on the sample surface or collimated.
Fast – no moving parts: typical measurement ~ 20ms
Any translucent films can be measured quickly and reliably.
BROCHURE: MProbe in-situ system


Extensive materials library: (500+ materials- new materials easily added). Support of parameterized materials: Cacuhy, Tauc-Lorentz, Cody-orentz, EMA and many more….

Easy integration with deposition control: OPC (DA2.0/3.0) and ModbusTCP interface. Hardware triggers (5V TTL) or programmable RS232 command.

Measured parameters: thickness, optical constants, surface roughness.
Chamber integration: Optical adapter (reduced kinematic mount) integrates smoothly with optical port flange, feed-thru adapter option for low/room temperature chambers
Integration with chamber control system (SCADA): build-in Modbus and OPC servers (optional)
