Optris Bottom Up Glass inspection system for glass tempering plants

With the new Glass inspection system from Optris, there is a new approach to temperature measurement in the production of low-e glass. Low emissivity glass poses a major challenge for infrared devices which are traditionally measuring the glass temperature from above when the panes moved out of the furnace during production.

The new Bottom Up Glass inspection system solves this problem by having two infrared imagers installed underneath the tempering line which measure the temperature on the non-coated high emissivity side of the glass.

The combination of two VGA imagers with a maximum field of view of 111° results in an excellent 1600 pixels scan line resolution on maximum 4,3 m (14.11 ft) scan width.

An ultra-fast CTlaser 4M pyrometer with 90 µs exposure time combined with the digitally controlled lens protection system (DCLP) is a reliable safeguard for both infrared cameras in case of glass breakage.
