Lens Shock & Vibration test
The industrial c-mount lens for Machine Vision applications is tested on shock and vibrations. The lens is designed with glasses that are fixed with a pressure ring. Lenses are tested under the following conditions:
- Vibration testing: a generated sine wave with an amplitude of 1.5mm and a frequency of 10hz-55hz will shake the lens for 25 minutes in three perpendicular directions
- Drop test: The lens, packaged in the standard package, is dropped 5 times, each from 1 corner, 3 edges and 6 sides at a height of 1m on a rigid surface (steel plate)
For machine vision applications where the lens might vibrate, we advise to use blue Loctite® glue to be sure that the lens locking screws for focus and aperture will not vibrate or loosen up.
