Optris has released a glass tempering scanner designed to measure temperatures from beneath the production line. The unit addresses accuracy issues common in traditional systems when monitoring glass with low-emissivity coatings.

Why it matters

Traditional top-down thermal monitoring often produces unstable readings on coated glass. By measuring from the underside, this system provides more reliable data for industrial tempering processes.

The scanner utilizes a PI 640i G7 thermal camera with a 120-degree wide-angle lens, supporting scan widths of 3.5 meters at 125 Hz or 4.3 meters at 32 Hz. It features a thermal sensitivity of 80 mK and operates within a physical housing measuring 722 by 145 by 72 millimeters.

The players

Optris

A manufacturer specializing in non-contact infrared temperature measurement technology for industrial automation.

The details

The system monitors the non-coated underside of glass to bypass the interference typical of low-emissivity coatings—thin metallic layers that reflect thermal radiation. By using a single thermal camera with a wide-angle lens, the scanner captures the full-width temperature distribution of the glass as it moves along the line. The unit is protected during operation by a remotely controlled shutter that shields the lens from debris and heat.

The Tech Race

Industrial glass tempering relies on precise thermal consistency to ensure material strength. This scanner moves the measurement baseline to the underside of the production line to resolve interference issues inherent in current top-down infrared solutions.

Operators in glass manufacturing can now install the scanner beneath their production lines to improve thermal accuracy on coated substrates. The system is designed for broad compatibility with a 100 to 240 volt power supply and includes a 10-meter cable for integration.

The takeaway

The move to under-line scanning mitigates the signal noise that plagues manufacturers working with low-emissivity coated glass. Industrial facilities should watch for official documentation regarding the cooling requirements when ambient temperatures exceed 45 degrees Celsius.
