Plastics come in so many different forms: transparent, translucent or opaque, color ranges from brightest white to dullest black. And finishes are polished to a matte texture, or a shiny but structured surface, or completely burred and chaotic.
4D InSpec’s ability to measure is largely independent of finish and color. Shiny surfaces, especially curved ones, tend to produce points of data dropout in a measurement, but there are simple steps to minimize them or make them inconsequential, explained in our support documentation.
In many cases, plastics will measure in a very direct way: position the optical head in the focus zone slightly away from the surface, and click the measurement button on the gauge or on the touchscreen. But some features, such as interior walls and curves may require a fold mirror –an accessory kit can be purchased with the gauge– to let you get a good angle in a tight location.
In the photo above, the fold mirror accessory is visible.
