Who Are the Leading Manufacturers of the Best Infrared Thermal Imaging Cameras?

Thermal imaging cameras came into being sometime during the 1950s for military application. Also known as thermographic cameras or infrared imagers, these cameras used to be bulky devices at one time. This was because the technology of the time required liquid nitrogen for cooling the detector system. The classified nature of the technology and the exorbitant rates meant that these cameras hardly available for use in various civil and commercial applications. This changed in the following decade. The development of uncooled detectors and advances in infrared viewing technology made these cameras more affordable. Today, numerous manufacturers provide a diverse range of thermal cameras across the world. Some of the major manufacturers comprise:

Jenoptik: Founded in 1991 in Germany, Jenoptik has a presence in around 80 countries across the globe. An integrated photonics group, it operates in domains such as lasers & material processing, optical systems, industrial metrology, traffic solutions and defence & civil systems. Its clients include businesses in the semiconductor equipment manufacturing, automotive supplying and medical technology industries. The IR-TCM 640 High Resolution IR Module and the VarioCAM High Resolution thermography cameras are among their most popular thermal IP cameras.
Nippon Avionics: A Japanese company with over 50 years of operational experience, Nippon Avionics specialises in developing and designing data processing systems. In addition, it manufactures aviation equipment, communication equipment, image processing equipment, medical equipment etc. Among its several thermal imaging cameras, the InfReC R500 series and the Thermo Tracer H2640 are very popular. 
Infrared Cameras Inc. (ICI): A US-based company, this manufactures complete infrared systems and software. ICI also specialises in providing comprehensive engineering and OEM solutions. With over 20 years of experience in the industry, ICI provides a wide range of infrared cameras admirably suited to the thermography market. Their IR-PAD series of products incorporate a 320 or 640 Resolution Thermal Core into a Windows-based tablet PC. 
IRCameras: This company is a leading service provider of high performance, customisable infrared imaging systems. In addition, it also specialises in offering Integrated Dewar Cooler Assemblies (IDCAs). IRCameras offers a diverse range of cameras suited for meeting scientific, industrial and military needs. They offer an assortment of standard and custom Short Wave Infra-Red (SWIR), Medium Wave Infra-Red (MWIR) and Long Wave Infra-Red cameras. Some of their most popular products include the QuazIR HD+, the Niatros Optical Gas Imagers, the Short Wave 900 series and the Mid Wave 900 series.
DALI Technology: Established in 1984, DALI Technology is among the top manufacturers and suppliers of thermal image cameras and digital video recorders. With over 20 years of operational experience, this company is based in Hangzhou, China. The DL700E+, the DL700C+, the T6-P, the TE and the TEi are among its most popular products.
Therm-App (by Opgal Optronic Industries): Since it began operating in 1983, Opgal has specialised in developing high performance, versatile visualisation hardware and software products for a variety of markets. Opgal’s focus on research, development and innovation led to the emergence of Therm-App. Therm-App refers to a compact thermal imaging camera that blends easily with the benefits offered by Android devices. These high resolution night vision and thermography Android thermal cameras have revolutionised the way thermal imaging technology works. Not surprisingly, these are the best thermal cameras you can use on your smartphones.
