24V / 150W Point Light Source Detector Tester For Ordinary Plate Glass

Point Light Source Detector Tester For Ordinary Plate Glass

1. Introduction
DG-5A point light source detector is a special equipment used to detect ordinary plate glass.
I. Working principle
Ordinary plate with a point light source at a certain distance, a certain Angle of illumination, the glass rib will produce some bright lines on a plane behind the glass plate, the brighter the line, the heavier the glass rib,
The instrument adopts this principle, using the light source of the slide projector to illuminate the glass, placing a white screen behind the glass plate, and comparing the bright line of the glass bar standard sample confirmed by glass experts with the bright line of the sample.
To determine the grade of the glass sample. The placement of the equipment is shown in the figure
2. Operation method
