Live Track focus tracking technology on the Renishaw inVia Qontor Raman microscope enables the analysis of samples with uneven, curved, or rough surfaces.

Renishaw has added Live Track focus tracking technology to the inVia Qontor Raman microscope, enabling the analysis of samples with uneven, curved, or rough surfaces. The microscope allows users to acquire accurate and reproducible spectra from samples with extensive topographic variations.

The focus is maintained in real time during data collection and white light video viewing, removing the need for manual focusing, pre-scanning, or sample preparation, the company reports.

The LiveTrack technology provides continuous feedback to the sample stage, which adjusts to follow the height of the sample. This ensures the laser maintains focus during data collection and when manually moving the sample during white light video viewing. Optimum focus is maintained across uneven, sloping, or dynamic samples, limited only by the maximum travel of the stage.
