Thermal Lens Options

Do you have a Lens on your Shopping list? I've wanted to get a full set of optics for sometime so this month I decided to get the 7 and 15 degree lens to fit both my T650sc and A655sc. One reason other than it just looks cool to have…

FOV Calculator

How can I get FOV in meters or feet for different distances? We are pleased to announce that we have launched an online FOV (field-of-view) calculator for all thermography camera–lens combinations. Knowing the FOV and the depth of field at certain distances is of paramount importance to many of our…

How is NEDT measured?

How is NEDT measured? NEDT (noise equivalent differential temperature) is the key figure of merit which is used to qualify midwave (MWIR) and longwave (LWIR) infrared cameras.  It is a signal-to-noise figure which represents the temperature difference which would produce a signal equal to the camera’s temporal noise.  It therefore represents approximately the…

Measuring temperature at long distance

At what distance can the camera measure an absolute temperature? Measuring temperature at long distance. A measurement result is not primarily a function of distance, but rather how large the area of interest is compared to the whole image. We recommend that the object size is not less than 3 x 3…
