With one 30-second acquisition, a device can be characterized using a Zeta 3D optical profiler for microfluidics. Channel width and depth are easily measured. The profile of a channel can also be determined to evaluate the degree of bowing along the channel length.
Microfluidic open well dimensions analyzed using a Zeta 3D optical profiler
For example, the X and Y dimensions of an open well structure, shown here next to a covered channel, can quickly and accurately be determined.
The width, depth and amount of bow determine the flow rate through a microfluidic device. Area roughness and volume measurements can also be quantified. These analyses are quickly calculated with 3D images from the Zeta optical profiler.
In addition, it is obvious if a sealed device is leaking as the change in refractive index is apparent due to the surface focusing technology of the Zeta profiler.
