focus
The condition which provides the sharpest image. Achieved by optimizing the distance between the object and imaging optics.
FOV
See field of view.
I
Illumination, back Lighting applied from the back of the object to create a silhouette when the object is viewed by the camera. illumination, front Lighting applied to the object from the same side as the camera so that surface features can be viewed on the video monitor. L
LED
See light-emitting diode.
lens A transparent optical component consisting of one or more pieces of optical glass with surfaces so curved that they serve to converge or diverge the transmit-ted rays from an object, thus forming a real or virtual image of that object. light-emitting diode A semiconductor diode that emits light when a voltage is applied to it and that is used especially in electronic devices (as for an indicator light). M
mag
See magnification.
magnification
The process of enlarging the apparent size, not physical size, of something.
magnification, lens
In a vision metrology system, the image size in the CCD plane divided by the corresponding object size.
magnification, image
Magnification on monitor. Image size on the video monitor divided by the corresponding object size. Same as lens magnification in a properly adjusted optical comparator.
