MEASUREMENT & MONITORING

Overcoming Production Challenges of Ultra-Thin Glass

Infrared temperature measurement ensures improved accuracy for better control of the production process and lower stress to flat glass sheets .
Measuring the temperature of ultra-thin glass at less than 1 mm thickness is a difficult task . Products such as smart phones and tablets incorporate this type of high-quality glass requiring a low-defect rate . Moreover , the general tendency for displays is to use even thinner glass (< 1 mm ) due to weight and energy reasons . But when using a 5 µ m instrument for measuring such thin glass , the material is no longer opaque . The transmittance rises and background signals can no longer be neglected at this wavelength .
The full digital core sensor design of the IN 6 / 78 pyrometer provides a wide temperature range with high accuracy . It is equipped with specially designed and coated high-end optics , which reduce the effects of ambient reflectance and guarantee the best possible accuracy .
Advanced Energy are presenting their solutions during glasstec in Dusseldorf at booth D31 / hall 15 .
The Impac ® IN 6 / 78 pyrometer by Advanced Energy is specifically designed for non-contact temperature measurements on the thinnest of glass surfaces . Its special 7.8 μm wavelength enables users in dedicated glass applications to accurately and reliably measure glass sheets below 1 mm thickness ( ultra-thin glass ). As such , it sets new standards for stress-free sheet glass production on manufacturing lines . The version IN 6 / 78-L is equipped with optics with a better field of view for the measurement of small objects . The high-speed version IN 6 / 78-H has a shorter exposure time of only 30 ms and is suited for fast measuring tasks . www . advancedenergy . com | info @ aei . com
