The Optris PI 640i G7 infrared camera, specifically designed for the glass industry, operates in the G7 spectral range and is now available with the innovative 120° ultra-wide-angle optics. This groundbreaking lens, the first of its kind in industrial infrared thermography, delivers an unprecedented 120° x 100° field of view (FOV), enhancing monitoring capabilities for large-scale industrial processes, glass tempering, and other glass manufacturing applications.

With a high optical resolution of 640 x 480 pixels, fast image sampling up to 125 Hz, and a dedicated line scanner mode, the PI 640i G7 provides detailed, accurate, and innovative infrared images of glass sheets and products. Its superior radiometric measurement characteristics and exceptional image quality ensure precise measurement and detection, particularly in line scanner mode, making it ideal for glass manufacturing processes.

Capable of measuring temperatures up to 3000 °C, the PI 640i G7 offers a range of interchangeable optics, from telephoto lenses (15° x 11° FOV) to the new ultra-wide-angle lenses (120° x 100° FOV), allowing you to select the perfect lens for your application. This high-performance, uncooled infrared camera comes equipped with industrial accessories and a free-of-charge software package from Optris, ensuring seamless integration and operation.

The PI 640i G7 is a high-performance infrared camera designed to meet the needs of both researchers and process engineers. The PI 640i G7 thermal imager is a versatile, high-performance infrared camera that supports remote infrared temperature measurement applications for research and process control applications. In its standard configuration, this versatile thermal imager boasts high VGA resolution and image quality, capable of measuring the full temperature range from -20°C to 900°C. The camera can be calibrated for high-temperature infrared measurements with a temperature range of up to 3000°C. Superior radiometric measurement characteristics and high image quality define the Precision Line of Optris.

Accurate temperature measurement of glass relies significantly on emissivity, a crucial factor that varies depending on several influences and must be carefully considered according to the specific application. The special G7 spectral range of 7.9 µm matches the glass material’s highest emissivity, which eases remote temperature measurement as the spectral region of reflectivity and transmissivity is minimized. In addition to reduced reflection issues, another advantage is the decreased angle dependency of glass surface emissivity within this wavelength range. As a result, surface temperature can be measured independently of reflection, even at inclined viewing angles.
Unlike other infrared cameras with smaller pixels, the optimal pixel pitch size of 17 µm for long-wavelength infrared radiation allows a small measurement field of view (MFOV) of just 3 x 3 pixels. The superior quality and larger size of optics also guarantee high image quality, with minimal image distortion and uniform attenuation maintained across the entire image. A wide variety of interchangeable lens optics are available to properly frame and maximize pixel count on the target to be measured. The infrared camera supports a frame rate of 32 Hz in standard mode or 125 Hz in the high-speed subframe mode to monitor fast manufacturing processes.

The PI 640i G7 works with Optris PIX Connect software, available as a free download with updates provided on a no-charge basis. The PIX Connect package includes the ability to seek hot spot and cold spot locations, histogram, temperature profiling, image subtraction, and other thermal image processing tools. For researchers and process engineers, the PC-based PIX Connect platform offers a powerful thermal image processing capability that allows users to extract and document fully calibrated temperature measurements from any pixel in the scene. Time-versus-temperature data can be extracted from both live and recorded thermal video files containing stored temperature data. Additionally, the software supports data collection of the highest, lowest, and average temperatures from areas of any size or shape, as well as from complex alarm signals. Engineers can replay stored thermal video frame by frame, enabling them to capture and store radiometric images and trigger snapshots during temperature changes.

The PI 640i G7 revolutionized the idea of line scanners in the glass industry. Glass line temperature measurements are facilitated through a special line scan feature of the PIX Connect software. This feature converts the two-dimensional visual output from the thermal imager into a continuous display of temperature variations across a single line, enabling accurate monitoring and analysis of temperature fluctuations along the glass line. Traditionally, line scanners are used in the glass industry for various measurement procedures. In these devices, a point detector is coupled with a rotating mirror to generate a linear optical scan of the object. These devices are bulky and expensive, requiring a lot of manual effort to set up. When using an infrared camera as a line scanner, an arbitrary line is selected from the detector array. In addition to the more compact construction and the lower price, there are two significant benefits: the line to be scanned can be positioned and dimensioned anywhere using the software, and the user receives a complete IR image effectively as additional information – these are important advantages, especially during system setup. Infrared cameras can accurately measure the surface temperatures of moving measurement objects using minimal apertures. This function is particularly significant in the glass industry since the glass temperature directly impacts the quality. Accordingly, temperatures are recorded at many points during production and transmitted directly to the process control system. With this mode, the infrared camera becomes the perfect replacement for bulky mechanical infrared line scanning cameras using a fraction of the space necessary for mounting older mechanical line scan technology.

For example, the PI 640i G7 with a 90° lens can scan the complete glass sheet width using the float process (Up to 4 m). Multiple IR cameras and infrared images can be merged into the software if a larger width is required. Using a subframe mode of 640 x 120 pixels, data can be captured at 125 Hz, which allows undistorted images without image blur.

The small PI 640i G7 camera head was designed to move easily from the lab bench to small spaces on the factory floor. The robust IP 67 (NEMA 4) can withstand ambient temperatures from 0°C to 70°C without any enclosures. A full family of accessories equips the camera for data collection and temperature control in extreme process environments. Water-cooled enclosures are available to protect the camera in ambient temperatures as high as 315°C and include mounting provisions for the Industrial Process Interface referenced below. Air purging accessories keep the optics free from the attenuating effects of factory dust or vapors and are factory-designed and tested. Thermal imager outdoor enclosures with integral heating equip the PI640i G7 thermal imager for outside mounting locations.

The PI 640i G7 infrared camera and PIX Connect software platform were meticulously crafted to seamlessly support the flow of temperature data from the camera to external Programmable Logic Controllers (PLCs) or control interfaces. With the Industrial Process Interface accessory, current or relay outputs containing temperature or alarm data from specific areas can be sent to an external PLC. Furthermore, external triggering functionality enables the capture of a single image or live video sequence when conditions align with user-defined temperature thresholds.

The PI 640i G7 infrared camera is designed and manufactured in Germany and offers calibration certificates for customers who need to document traceability.
