High-precision Optical Profile Projector
Feature:
-
Optical Profile Projector is widely used to measure the outline of the products, such as aluminum extrusion,stamping,precision mould, etc.
-
Optical profile projector is also known as optical comparator. The measuring happens in any of several ways. The simplest way is that graduations on the screen, being superimposed over the silhouette, allow the viewer to measure, as if a clear ruler were laid over the image. Another way is that various points on the silhouette are lined up with the reticle at the centerpoint of the screen, one after another, by moving the stage on which the part sits, and a digital read out reports how far the stage moved to reach those points. Finally, the most technologically advanced methods involve software that analyzes the image and reports measurements. The first two methods are the most common; the third is newer and not as widespread, but its adoption is ongoing in the digital era.
