All gases have different properties. Some gases certainly do emit infrared energy. However, they normally only emit in a very narrow spectral band. Thus seeing a gas is certainly possibly by using a camera adapted with a suitable spectral filter. Seeing the gases is not the same as measuring …read moreContinue reading →
Why does an infrared remote control not affect thermographic measurements, while the reflection of a person can?
This is a question of wavelength. Infrared remote controls operate in the near infrared range (e.g. 0.85 µm or 1.55 µm), while thermographic cameras usually work within MWIR (3-5) µm, or LWIR …read moreContinue reading →
What is thermal imaging? How does it work? This story, published by Sanjiv Fernando, on Mongabay an environmental science and … Continue reading →
This is a regular question, and to be often it is often not understood.
There are several thermography companies that do thermography and ignore wind totally. Several others only take it into account by woking below a preset limit, like 10 m/s. This limit of 10 m/s is to …read moreContinue reading →
This depends on the capability of the thermographic camera used.
Standard uncooled cameras fitted with a microbolometer detector allow non-contact temperature measurement as low as -40°C. Below this temperature, they are still emitting in the infrared region, however due to Planck’s Law the infrared intensity emitted by objects is …read moreContinue reading →
Hai appena sostituito le tue vecchie finestre con nuovi serramenti super prestanti ? super isolanti ? super fighi ? Ma nonostante tutto, devi tenere la sciarpa in casa per via degli spifferi ?
Sembra assurdo ma non sei l’unico che si è trovato in questa situazione, molto probabilmente le te finestre …read moreContinue reading →
I get asked this from time to time.
For most materials we cannot see below the surface at all, never mind measure a temperature below the surface. The vast majority of common materials are thermally opaque, this means that the camera can only detect radiation emitted from the surface. For …read moreContinue reading →
