Test and Measurement Service

Klar now offers a fast turnaround service to provide clients with two dimensional photoluminescence maps of their samples. For a nominal fee, Klar will deliver maps, data sets, and peak fits for samples ranging from sq. microns to sq. cm sizes.

At this time, Klar is offering visible-near IR spectra at each of up to 10 Million sample points. UV measurements should be available in the late fall of 2019.

Examples of our micro-PL spectra and our mapping capabilities are displayed below. Scans are automated and can accommodate samples ranging from a few microns up to 100 mm on an edge. Peak fits are accomplished using Klar’s proprietary analysis software

If you study material composition, defects, fracture lines, topographical features, and other properties, contact Klar to set up a project. New clients may reach us at klar@klarscientific.com for quotes for custom measurements.
