Service life of electro-chromic

Put EC lenses into set 20℃thermostat conduct 5000 cycles under -20, conduct 7000 circulation under room temperature, do 30000 circulation under 50℃ and 95% humidity, do 50 000 circulation under 50

The definition of a cycle: power on for 10s (1.25V direct current) and power off for 20s

Thermal shock test

No more than 2 minutes when transfer from -40℃ refrigerator to 85℃ oven: repeat 500 times circulations. And no current is allowed in circulation. Put EC lenses under the home temperature before take them out

The definition of a circulation:85℃ for an hour and -45℃ for an hour
