Mono Cooling Test
Finished wiring up the TEC and fan for attachment to the controller, and ran a preliminary test today. I should point out that at this point the cold finger is not insulated with foam sheet (as is my usual practice), but does have the Plastidip coating. Starting point was ambient 20C and humidity was 40%. On controller startup, with camera powered up, the temperature dropped rapidly, in about four minutes reaching its set point of -7C; which is a Delta T of -27C from ambient. This is a good result and in line with the same test of my original colour camera test. Ran some Offset/Bias frames at 1/4000th of a second, and then did a couple of three minute darks at ISO1600, they look identical when stretched.
I have attached a couple of pics of the mono camera under test, notice the frost build up on the cold finger.
Looking good for on scope testing soon.
