Point-Source Projection
Controlled illumination makes striae visible on the projection screen.
DG-8 Point-Light Source Inspection Instrument
Visual Detection of Striae in Flat Glass
DG-8 uses point-source projection and visual observation to make striae within flat glass visible as bright-line patterns on a projection screen, supporting direct assessment of striae severity.
Designed for flat-glass striae inspection under controlled optical geometry
Striae Inspection
System Overview
Point-Source Projection for Striae Evaluation
Detection Target
Striae in flat glass
Light Source
24 V / 150 W
Projection Screen
100 inch
Sample Support
Height adjustable and tiltable
Striae alter the optical path through the glass and appear as bright-line patterns on the projection screen for visual evaluation.
Key Features
Inspection and Control Functions
Visual Assessment
Bright-line shape, intensity and distribution can be observed directly.
Adjustable Sample Support
The sample holder can be raised, lowered and tilted.
100-inch Projection Screen
Large projection area supports clear observation of transmitted patterns.
BRAUN E130 Projector
The source document specifies a German-imported BRAUN E130 slide projector.
Controlled Test Geometry
Mechanical support and fixed optical geometry help maintain consistent inspection conditions.
