work distance

Many users want to inspect a wide variety of workpieces with a single unit when introducing inspection equipment.

However, as the height of the workpiece changes, the workpiece distance changes, creating problems of focus and resolution.

WORK DISTANCE (WD) REFERS TO THE DISTANCE BETWEEN THE "WORKPIECE" AND THE "CAMERA.

NOTE THAT IF THE WD IS NOT APPROXIMATELY CONSTANT, THERE WILL BE DIFFERENCES IN THE TEST RESULTS.

THE SAME IS TRUE FOR LIGHT WORK DISTANCE (LWD), WHICH INDICATES THE DISTANCE BETWEEN THE "WORKPIECE" AND THE "ILLUMINATOR.

HOWEVER, IF DIFFUSE LIGHT IS USED, A SLIGHT CHANGE IN LWD WILL NOT CAUSE MUCH CHANGE IN THE IMAGE.

IF WE WANT TO HAVE VERSATILITY IN INSPECTION EQUIPMENT AT A LOW COST, WE NEED A MECHANISM TO KEEP WD AND LWD CONSTANT.

Depending on the variety

Do you want to move the camera and illuminator?

Is the height adjusted by the jig on which the workpiece is placed?

Thinking about reducing handling effort.

It is also a good idea to narrow down the work to be inspected.
