Ok, so the power supply I ordered FINALLY came. I bought it from Cascade Laser (the same company that used to distribute these Micronviewer cameras). They charged me the RIPOFF PRICE of about $200 for the power supply! While I'm upset they decided to price gouge me, they did say that they had to contact their manufacturer to get one made (apparently these aren't a stock item, now that the camera itself is seems to be obsolete), so they may have considered it worth more as a custom item or whatever.
So, I got the power supply and plugged it in, and got some pics with my USB video capture dongle. I've attached these pictures to this post. They include pictures with no lens and AGC, and also with a lens with all 4 gain settings (AGC, MGC low, MGC medium, and MGC high), and with the lens capped on the first 3 gain settings (AGC, MGC low, and MGC medium). The no-lens picture (entire sensor illuminated with room light), showed an interesting rectangular feature that's at an angle. I'm not sure what it is. Is it normal or some defect?
The various gain pictures, show that not only is the gain (amplification) of the signal altered, but so is the offset (blackpoint). By the time you have the gain up to high, even WITH the lens cap in place (I didn't bother to test it with the lens cap off, as the entire picture would be washed out and useless), the entire picture appears white. Likewise, when the manual gain setting is medium, it appears a flat gray color across the image with the lenscap on, and with the lens cap off, the entire picture's blackpoint is this gray color (nothing appears any dimmer than that gray color). I suspect that this is NOT how the gain should be working. AGC however seems to work properly (adjusting only the gain, while keeping the proper blackpoint).
With the lens cap on, and AGC also on, I noticed that the last image the camera saw, appears to be "burned in" to the tube sensor temporarily, even if that image wasn't from a bright light source (just normal room illumination). It takes a minute or 2, for the image to finally return to normal (which with the lens-cap on is a flat gray, as the AGC finds the max and min levels are approximately the same, and so adjusts the picture to be mid-gray as the image brightness level).
Also, no matter how I adjust the lens, I can't get it to be very sharp. I suspect this may be an electron beam focusing issue in the image sensor tube. I may need to somehow calibrate the electron beam focusing.
Also, in case you are wondering, the object this camera is pointing at is my bed. Above my bed is a solar system poster, and there also happens to be a cardboard box on the floor (I should have moved it before capturing these pictures). Also, I was only able to capture anything at all, because this camera can see both visible light and the NIR+SWIR parts of the spectrum. My room lights are incandescent, so emit almost 100% visible light. I'm still going to need to get an NIR or SWIR longpass filter for this camera. That will cost about $80 though, so I think I will wait a bit, as I've already spent $500 on the camera, and $200 on the replacement power supply.
