3.Electrical Specifications

Remarks:

(1) All parameters in the data sheet are specified for a 1kHz sine wave edge.During the test phase, a square wave signal can be applied using a function signal generator, provided that the signal contains no DC voltage. The use of DC voltage or a combination of DC/AC voltage will cause abnormal behavior of the tunable lens and shorten its service life.

Important Note:

The liquid zoom lens is sensitive to Electrostatic Discharge (ESD). Exercise caution against static electricity during operation.
