FLIR Systems has published a technical note that discusses and compares the advantages of cooled versus uncooled Optical Gas Imaging (OGI) technology for different industrial applications.

Historically, OGI cameras have been designed with cooled infrared (IR) detectors that offer several advantages over uncooled detectors – but they often come at a higher cost. Advancements in the technology of uncooled detectors have allowed the OGI camera manufacturers such as FLIR to design and develop lower cost OGI solutions for a growing range of industrial applications. However, although lower in cost, there are some limitations to OGI cameras with uncooled detectors versus those using cooled detectors.

Before comparing the benefits of the 2 technologies the authors provide a useful background to the scientific theory of OGI cameras.

The technical note discusses when selecting a camera for your OGI needs, the first factor to consider is ensuring the camera in question can visualize your target gas. Though price is often an important consideration in choosing an OGI camera the article reviews the key advantages of a cooled OGI camera such as increased sensitivity and image quality which may not only impact your ability to visualize small leaks but may also be important when trying to meet regulatory standards.

The authors also discuss that there are advantages to uncooled OGI cameras beyond a lower purchase price including that they also cost less to maintain due to the simplicity in design with no cooler needed – potentially making them more appropriate for continuous, 24/7 operation applications.

FLIR Systems specialises in technologies that enhance perception and awareness.  The company brings innovative sensing solutions into daily life through its thermal imaging and visible light imaging technology and systems for measurement, diagnosis, location and advanced threat detection.  Its products improve the way people interact with the world around them, enhance productivity, increase energy efficiency and make the workplace safer.

FLIR Systems has six operating segments – surveillance, instruments, OEM and emerging markets, maritime, security and finally, detection. Of these six, ‘instruments’ is of greatest interest to trade and industry and the second largest segment in the company’s portfolio. This division provides devices that image, measure and assess thermal energy, gases and other environmental elements for industrial, commercial and scientific applications.

These products are manufactured across five production sites, three in the USA and two in Europe; Sweden and Estonia.

A model to suit every application and budget
The options that FLIR Systems provides for measuring temperature and studying thermal performance have never been greater.  Not only does the company offer a huge range of models to suit all thermal application needs but the technology is also affordable and very easy to use.  Thermal cameras now come in various shapes, sizes and degrees of sophistication and FLIR continues to invest heavily in the development of new and complementary technologies to differentiate itself from competitors.

An important milestone in the development of thermal imaging has been the introduction of the FLIR Lepton® core, a micro longwave detector, the size of a mobile SIM.  This has allowed thermal imaging to be repackaged to meet the needs of an even wider audience and, in combination with another new technology called Infrared Guided Measurement – IGM™ – has led to the development of a range of test and measurement meters with imaging capability.

Another important growth area for FLIR thermal imaging is in continuous monitoring to assure quality and safety.  Through its introduction of discrete fixed mounted thermal cameras which are fully compliant industry standard plug-and-play protocols, FLIR Systems has provided industry with infrared machine vision which is instantly ready for quick and easy network installation.

Protecting assets and people from fire is an area for which thermal imaging is least known but, thanks to FLIR Systems’ development, it is now one of the most cost-effective methods available.  Its application flexibility and rapid return on investment present an attractive proposition for any site or safety manager.
