A candidate for the thermal camera to be used for Assembly and Testbeam is the FLIR E45. The principal characteristics are:
  • Range of detection: -20 to 250 degrees C
  • 50 Hz freqency
  • 160 x 120 pixels
  • choice of objectives:
    • Telephoto 9x7 degrees; minimum focal distance 1.20 metres, giving field of view of 19x14 cm and a minimum feature size of 1.17 mm
    • Standard objective 19 x 14 degrees; minimum focal distance 30 cm, giving field of view of 10x7 cm and a minimum feature size of 0.62 mm
    • wide angle lens 34 x 25; minimum focal distance 10 cm, giving field of view of 6 x 5 cm and a minimum feature size of 0.39 mm
    • very wide angle lens 60 x 45; minimum focal distance 10 cm, giving field of view of 12 x 9 cm and a minimum feature size of 0.78 mm

The main difference between the E45 and the E25 is that the E45 gives the possibility of changing lenses, on the E25 it is fixed. The cost of each lens, which has the infrared sensors integrated, is approximately 5000 Euros.

The thing we want to look at principally (the hybrid) is approx 12 x 18 cm, so the standard objective would work well at a distance of 50 cm, the wide angle at 30 cm, or the telephoto at 1.20 m.

The quality of the images can be seen in the following photos:

The brochures for the various cameras can be seen here, E25, E45, P25, A20M-Researcher, A40M-Researcher, the specifications of the field of view of the various lenses can be seen here, and the dimensions of the outer housing of the camera here Dimensions_76, Dimensions_77, Dimensions_78.

Our current offers can be seen here.

Comments:

- It is possible to take the picture remotely via the USB cable. The focussing is done by eye. But of course we can mount the camera in a standard position and move it relative to each mounted module. - What window do we need to view the module in vacuum. A recommended company is SOREM; more information soon. - The pictures obviously would improve with more pixels. The company InfraTec offer cameras with broadly similar characteristics, but 320x240 pixels, for an extra 10,000 Euros or so. They also have a version with no screen - direct to computer, we will try to obtain an offer for this. - Do we need to go to -40 degrees. This would mean moving to the A20 or P45 models in FLIR, for an extra 11-15k Euros - Can we be sure that the camera outputs not only the jpeg files but also bitmaps containing all the information. This question has been asked to the company. It might be that we need to purchase their software which costs (a hefty!) 2200 Euros.
