The MProbe 20 Series: Thin Film Thickness Measurement and more

The MProbe 20 series is a desktop system for thin-film thickness measurement. The measurement is based on spectroscopic reflectance and uses fiber optics retro-reflecting probe. This approach yields a compact, easy to use and affordable system.

The system is user friendly and easy to setup – you will be ready to start measurements right away. Everything is included for samples measurement: spectrometer/ light source (main unit), fiber optics probe, sample stage, software, calibration/reference sample.

Our extensive materials library has 500+ materials. New materials can be easily imported or created/added to the library. Support for a wide range of parameterized materials (from Cauchy to Tauc-Lorentz, etc.) is included.

One-click measurement combines data acquisition and data analysis. Everybody is a measurement expert with MProbe!

For advanced users, we have all the sophisticated tools including sensitivity analysis, error-estimator, simulation, filmstack switching, global optimization, layers and materials linking, etc. that can be used for advanced applications development

Reflectance and transmittance spectral data can also be used as a raw measurement (for example, as in spectrophotometer) or a for a wide range of other applications e.g. chemical concentration (we have a range of flow cells), filters and coating testing, etc.

Why use MProbe

Flexible: select the best hardware configuration for your application

Affordable: up to 50% savings as compared to other commercial instruments
