Description
The OPT-COB1240-LQL is listed in OPT's series “Cobra Liquid Lens” with focal length 12 mm, aperture F4.0, image circle Ø9 mm (1/1.8"). Further key data: working distance 100 mm - ∞.
The Cobra lenses with liquid lens focus electrically: the integrated liquid lens focuses in under 4 ms, repeatable to ±0.1 dpt, and the plug connector can be rotated by 360°. Up to 145 lp/mm for 3.45 µm pixels and sensors up to 2/3". They solve tasks with varying object heights without a mechanical autofocus: labels on boxes of different heights, bearings and shafts, holes on several levels.
When choosing a lens, what counts is the interplay of sensor size, pixel size, field of view and working distance - the focal length alone says little. If you tell us your camera and inspection task, we check the combination and, if needed, suggest suitable lighting to go with it. The dimensional drawing and the STEP model are included.
