Stroboscopic microspectroreflectometry of lens-less on-chip microscope PCB with CCD
Printed cirquit boards with charge coupled devices for on-chip lensless microscopes may be tested not in wetherometers and under solar simulators, but also under the experimental spectroreflectometric setup based on DATACOLOR 3890 with microphotometric and RS232-port-assisted data transfer into the PC memory.
The DC 3890 is a spectrophotometer for color data acquisition using reflectance measurement. For each measurement, the sample of 16 measured values in the range of visible radiation (400 to 700 nanometers) compared to a reference surface in the sphere photometer. A double-beam monochromator with two holographic gratings and two diode arrays with selectively paired photodiodes ensures high accuracy and repeatability. The microprocessor-controlled evaluation unit controls the collection and processing of measurement data.
