The Image Science Associates ColorGauge Nano Target has the identical 18 colour patches as the GretagMacbeth™ ColorChecker®, plus 12 spectrally neutral grey patches to assess correct exposure and white balance in close-up or macro photography applications.

This matte set is available with AR coated optical grade quartz cover glass and are useful in harsh, wet imaging applications. Each has been tested to be water and alcohol proof in submersible environments.
