Phase Measurement Deflectometry (PMD), after nearly 20 years of research and development, has been proven to be one of the best solutions for fast measurement of aspheric and free-form surfaces. WyseLight has combined its patented coaxial calibration measurement technology solution to solve the two major application problems of screen calibration (Identification) and complex phase step-by-step deflection unpacking algorithm, and has achieved the instrumentation of PMD technology for the first time, marking that this technology has entered the stage of widespread application.
WyseLight's Raymaster aspheric measuring instrument can achieve fast measurement of aspheric and free-form surface shapes, with a measurement accuracy of up to λ/40 (about 15nm rms), and does not require complex adjustment, optical platform, or professional operation.
