Four-station lens air tightness detection

The four-station air tightness test uses air as the detection medium for the lens airtightness detection, and can simultaneously detect the four lenses at the same time.

A detection pressure of 70 kPa is used. The leakage value is not more than 80pa, that is, the IPX7 waterproof test level, the test is completed as fast as 7 seconds.
