What spectral range should my infrared camera have?
Please note: To minimize temperature measurement errors resulting from emissivity inaccuracies, you should measure at a short wavelength. DIAS Infrared offers the world’s most manifold range of fixed infrared cameras with optimal adjustment to your measurement task. Please read this article for more information. Here is an overview of all offered spectral ranges of our thermal imaging cameras.

Which infrared camera suits your requirements?
Depending on the application our fixed thermal imaging cameras are available with different thermal and spatial resolutions, spectral ranges and temperature ranges as well as with different housing variants. In addition the are numerous motor focus infrared lenses, including wide angle and tele photo lenses, for an optimal adjustment of the camera to different measurement objects and measurmeent object sizes at different measurement distances. Here is a detailed overview of our fixed infrared camera series and models. The table also includes the handheld high-temperature thermal imager PYROVIEW 480N portable.
