The CTlaser G7 offers non-contact temperature measurement for ultra-thin glass sheets, ranging from 100 °C to 1200 °C, making it ideal for accurately measuring temperatures of ultra-thin flat glass used in touch displays for smartphones and tablets. Featuring double laser aiming, the infrared sensor ensures precise marking of the measurement spot, providing versatility and ease of use with optics of 45:1 and selectable focus, along with a compact sensor head size. The pyrometer is suitable for ambient temperatures up to 85 °C without additional cooling and includes cooling and protection accessories for rugged environments. At an ambient temperature of 23 ± 5 °C, the system accuracy is ±1% or ±1.5 °C, with repeatability of ±0.5%.
Understanding the emissivity of glass is crucial for accurate temperature measurement. The unique spectral range of 7.9 µm in the G7 model aligns closely with the glass material’s highest emissivity, simplifying remote temperature measurement by minimizing the spectral regions affected by reflectivity and transmissivity. Leveraging this wavelength range reduces the viewing angle’s impact on the glass surfaces emissivity, addressing issues related to reflections and enabling accurate measurement regardless of reflection, even when observing from inclined angles.
Another notable feature of the CTlaser G7 series is its double laser aiming marks, which provide precise aiming support and minimize alignment errors. This innovative system utilizes two laser beams to trace the infrared optical path and accurately indicate the spot’s position and size, regardless of distance.
The CTlaser G7 pyrometer adopts a two-piece design with a separate electronics box, delivering advanced signal processing capabilities. Offering a wide range of analog and digital outputs, it ensures seamless integration into various industrial processes and control systems. Enhanced with Optris accessories such as air purging and mounting flanges, the CTlaser G7 is designed for integration into diverse manufacturing and process applications.
Manufactured and calibrated in Germany, these pyrometers undergo meticulous calibration to meet government standards such as PTB or NIST, ensuring the highest quality and accuracy. Optris provides comprehensive support for the CTlaser G7 series, including consultation on industrial applications and after-sales support, ensuring optimal performance and user satisfaction. With its precision, versatility, and reliability, the CTlaser G7 is a valuable instrument for temperature measurement in various glass processing applications.

Thermography software optris PIX Connect is included and license-free.All infrared cameras are delivered with the thermography software optris PIX Connect, developed specifically for the extensive documentation and analysis of thermal images. The Windows-based PIX Connect software enables users to tailor the infrared cameras to meet specific requirements. It analyses live and recorded temperature data and triggers alarm signals for process integration. The key to leveraging the Optris infrared camera is a correct configuration. This includes detailed device-specific configurations such as frame rate, measurement range adjustments, external communication settings, and USB/Ethernet configurations. Moreover, PIX Connect facilitates firmware updates and the download of configuration files over the Internet.
Optris offers several different SDKs for our Xi and PI thermal imaging cameras. Depending on the operating platform, the infrared camera, the coding language, and the hardware platform, different software interfaces can be utilized:
The Optris IRmobile allows users to set up and commission an Optris infrared pyrometer or infrared camera with an Android smartphone or tablet. This tool becomes handy for commissioning and aligning the infrared camera’s field of view or adjusting the configuration. The app analyzes the connected infrared camera‘s live infrared image stream with auto hot and cold spot detection. For pyrometers, a temperature-time diagram or the video signal is displayed. This app works on most Android devices running 5.0+ with a USB port supporting USB-OTG (On The Go).
