White Haze Scanner
After tempering, this channel reveals areas where damage to the glass surfaces has occurred due to the furnace. These areas are particularly noticeable when they occur in the middle of the pane. These areas are detected, located and presented to furnace operators in real time for rework, allowing workers to polish the defective surface areas before the glass is sent to further processing or to the customer. Unnecessary follow-up costs are a thing of the past!
The channels used
The Haze Scanner works as a stand alone solution in darkfield reflection. This avoids the need for complex preparatory work on the outfeed conveyor in individual cases. In combination with the Anisotropy Scanner, the White Haze channel works in darkfield transmission, since the Anisotropy Scanner must already have an illumination under the transport conveyor and Viprotron then uses the same gap for the White Haze illumination.
The testing processes
The test for White Haze is carried out in darkfield, as this is customary for low-contrast defect images. There are various display modes for displaying the results: for example, real photos in black and white or display in false colors to make it easier to identify the damaged areas in poor light situations in the production hall.
Areas of application
- Behind the tempering furnace
Focus
- White Haze in the middle or at the edges of a sheet
Modularly expandable
- The basis is the White Haze channel in darkfield reflection
- Expandable with an anisotropy channel (then White Haze in darkfield transmission)
Options to
- Improvement of the workflow (e.g. traffic lights, second operating station for furnace operators, etc.)
- Support for automation (connection to lines, ERP or PPS systems)
- Storage and use of data (dashboard, reports, archive)

FAQ
-
Ideally, the rework should take place in a darker environment and be supported by light falling from the side. If this is not spatially possible, at least the direct passage of light from behind should be avoided, otherwise the areas displayed on the monitor are difficult to find on the glass.
-
The simple retrofit installation was an essential goal of the development. Running the darkfield channel in reflection means that both the optics and the illumination are above the glass line. This avoids the need for changes underneath the conveyor. The drive can usually remain unchanged.
