Glast
Inline sensors of the GLAST series are mainly used for the inspection of highly reflective surfaces (such as stainless steel panels, aluminum sheets, painted surfaces and plastic foils) and transparent objects (foils, glass sheets, Plexiglas sheets).
A projection lens projects a line grid onto a line sensor using the object to be inspected, which functions as a more or less optimal mirror. Transparent objects are placed close to the line grid, which is then projected again through a projection lens onto a line sensor. In both cases, the quality of the object determines the quality of the video signal on the line sensor.
The reflection method operates at an angle of 30° (45°, respectively), with the optical axes of the transmitter and receiver components diverging from the vertical axis. In the beam-through method, the object to be inspected is perpendicular to the optical axis of the transmitter-receiver arrangement. In both cases, the distance between transmitter and receiver is approximately 135 mm.
Three different line gratings are available in both cases: 0.5 mm/0.5 mm, 1.0 mm/1.0 mm and 2.0 mm/2.0 mm. Learn more about how a gloss measurement with a GLOSS sensor works here.
