We first introduced precision Foucault testers over 30 years ago and they helped a whole generation of ATMs turn out those beautiful parabolic mirrors. This all new knife-edge tester greatly simplifies the mirror figuring operation. It is completely finished and ready to use. Constructed of aluminum and steel with the base and knife-edge platform in beautiful white Formica, it will give years of service. The true micrometer head allows .001 inch measurements.
