[Elphel-support] Operating temperature

[Andrey Filippov]

Hello Juha,

This is not an easy question to answer. The operating temperature range
depends on the particular requirements. The electronic components can
operate in wide temperature range - we have some cameras that for years
work under the direct Sun in Utah and we had some cameras in Chita, Russia
where the temperatures below -45C are common. The black anodizing from the
camera enclosures broke off because of the cold, but that did not have any
effect on the camera operation.

On the other hand, temperature variations influence optics - lens focused
for one particular temperature will be out of focus if the temperature
changes dramatically. We do make temperature compensated sensor front ends
for Eyesis cameras, but that is only compensated fro one particular lens
type. We measured uncompensated shift of focus ~0.2 um/C, the compensated
is under 0.03um/C.

Temperature variations of the distance to the focal plane may be less
critical if you have possibility to focus the camera fro that particular
temperature.

What is you application? What lens do you plan to use?

Andrey
