Dear Customers and partners,
in these series technical articles you can learn some important and useful knowledge regarding to how to choose industrial lens, how to finalize machine vision lens, what you should consider carefully when you face so many various lens, this is third article
Appropriate selection of industrial lens is very important for machine vision to play its due role. Therefore, the following points should be considered when choosing a lens:
1) The lens size should be equal to or larger than the camera imaging surface size.
2) Choose an appropriate lens focal length.
3) Considering the change of ambient light, light plays a very important role in the image collection effect.
4) Consider the best monitoring range.
5) The lens mount and camera mount should be consistent
Different kinds of industrial lens application
1. Fixed aperture lens: fixed focus and fixed aperture, mainly used in places with fixed ambient light;
2. Manual iris lens: fixed focus but adjustable iris, mainly used in places where the ambient light is fixed but the brightness is variable;
3. Automatic iris lens: fixed focal length, using DC voltage drive for a fixed range of ambient light variability;
4 Manual iris zoom lens: mainly used in places with variable indoor ambient light levels and different ranges;
5. Auto-iris zoom lens: mainly used in places where the outdoor ambient light level is variable and the range is different;
6. Electric zoom lens: mainly used in places where the light level is variable indoors and outdoors and the depth of field can be adjusted.
Because the lens is very important, before proceeding with the surveillance engineering design and planning, only by understanding the type of lens and its application method, and understanding the characteristics of its matching application, can the best imaging of the lens be used.
