Process monitoring & Quality control

What is process monitoring and quality control?

In industry today, reliability and accuracy are crucial issues to cut costs and increase productivity and quality. Continuous, real-time and on-line infrared imaging provides an important monitoring and control tool for production and plant processes.

Above the well-known thermal imaging cameras using the MWIR or LWIR wavelength ranges, SWIR imagers add significant value in process monitoring and quality control (QC) as they detect damages or defects that are invisible using thermal cameras.

Xenics cameras assist in controlling and steering mechanical and computerized manufacturing equipment like conveyor belts, machining tools and robotic arms.

What is process monitoring and quality control used for?

Temperature measurements in the process control and automation is widely used, not only for non-contact measurements, but also for the quality control of some processes like molding, soldering, sealing, sorting, etc. Thermal imaging (LWIR) cameras are widely used in the automotive, food or electronic industries. Low and high speed thermography imaging for high temperature materials like steel or glass can also be processed with SWIR cameras.

SWIR can see trough materials that are opaque for visible light. This allows measurement or detection of features like filing level, defects, artefacts, moisture, packaging inspection, etc. As water or moisture absorbs SWIR, this property allows analysis of maturity of vegetables, dryness of material, humidity content or filling level.

Spectral analysis in the SWIR wavelength is widely used for all kind of sorting applications like waste, food inspection, agriculture or mining industry.

What do we offer?

Customers continuously find new applications for system integration where cost, size and power are critical. Obviously, flexibility in terms of data and control interfaces is also important.

Xenics offers SWIR and LWIR (thermal) cameras for imaging and thermography. Our cameras are very small and lightweight, use very little power, and are relatively affordable (unlike other cooled cameras that can also operate in the SWIR and LWIR range).

What features are needed?

  • High image resolution
    The amount of pixels has an important impact on the image. The higher the resolution, the more detail your image contains
  • High frame rate
    High frame rates allow us to capture fast moving objects
  • Low noise level and high dynamic range
    A low noise level assures a high sensitivity, while a high dynamic range results in a high image contrast
  • Small pixel size
    A smaller pixel size results in smaller detectors - resulting in lower sensor production costs, smaller optics and eventually smaller cameras
  • Sensor temperature stabilization or cooling
    A cooled SWIR camera has a lower dark current, reaches lower noise levels and has a higher dynamic range. Several SWIR cameras in our product range are TE1-stabilized, TE1-cooled, TE3-cooled or TE4-cooled
  • Easy connectivity
    We offer several different interfaces for an easy integration into your system

Application notes
Industrial image processing in the near infrared spectrum gains importance as analysis tool in production lines The Lynx-TE1 SWIR line-scan camera gains importance as a liable tool for non-destructive analysis in production lines.
Thermal electronics inspection Xenics thermal cameras can detect heat defects in electronics before qualification, saving a considerable amount of time and money. The cameras can also be used for critical control of heat dissipation in a working instrument to optimize its life-cycle.
