Vision camera for extended temperature operation

[JamesHoare]

I need to be able to verify the operation of a display while a unit is being thermally cycled. Temperature ranges are -40C to +85C.

Thought about using some optice to send the image outside of the chamber, but this makes the lighting more complicated.

Is there a series of a cameras that would support this type of operation?

This is not an answer to your question, but something you have to be careful about is the convection in the heated air of the chamber moving air of differing densities between your camera and your display.  This is the effect you get looking down a hot road in the summer or looking just over a fire.  Normally it is not noticable at these fairly reasonable temps, but it could be a problem if you are looking for single pixel accuracy.

Also, you will generate frost on the camera at low temps and have it melting when transitioning to higher ones.  This can be a problem as well (ask you probably know).

As for the camera to use, I am at a loss.  The cameras I have used in the past all have specs that limit the max temp to a lower limit.

Sorry,

Bob

Hello James,
I am not aware of any cameras that will function within that temperature range.  I would suggest that you try contacting different camera manufacturers.  I have provided links to several camera manufacturer websites.  Try contacting them to find out if they offer any products that will operate within that temperature range.

Reviving an old post....

Has anyone come across any wide temperature range cameras?  I have a very similar application problem.  I thought about using some sort of enclosure to keep the elements out, however I would like to eliminate any additional glare that may introduce.  Thanks for any help.

Hi Nick,

The geometric matching algorithm can compensate to some degree to reduce non-uniform lighting (shadows, glare and light drifts) on objects. For a Camera I would recommend looking at the list Scott provided above. An enclosure would be another way to accomplish this as well.


Thank You,
