Securing the functionality of lab-on-a-chip devices

Microfluidic lab-on-a-chip devices (LOC) implement a multitude of occurring processes on the smallest of spaces. You can use Polytec’s sophisticated quality products to check, for example, the dimensions of microfluidic channels and find out how deep and wide the channels are, to determine the volume or to localize the flatness of your entire “laboratory”. No matter what LOC applications you’re deploying, Polytec offers you the perfect high-resolution solution for flexible use.

TopMap surface metrology systems with large field of view (FOW) and high z-axis resolution records an entire LOC’s channel depths with just one measurement. The telecentric, optical configuration has a parallel light beam path, which can be used to measure the channel base almost entirely without any shadowing effects. Keeping the z-axis resolution constant, some TopMap surface metrology systems allow to interchange lenses for quick and easy adaption of the lateral resolution for varying measuring tasks .
