Optical measurement a wide range of measurements from ultraviolet tofar infrared is possible.
Achieved the fastest test time ※1 in the industry.
Contact probe monitoring※2 can be performed even during measurement.

※1     According to our research
※2  Cannot be determined for single contact


We perform classification measurement with a very fast test time.
Demonstrates excellent performance in automated test systems on LED production lines. 


Even characteristic tests, which are time-consuming in normal tests, are measured at high speed.
TOTAL TEST TIME is an actual measurement value
Measurement content example
Each item setting TEST TIME 1ms ~ 3ms
IR (leak measurement) -5V applied TEST TIME 2ms or less
VF (small current) + 0.1uA applied TEST TIME 2ms or less
