While digging through the junk bins of Akihabara today I picked up what I thought was a CCD security camera. I interested in pulling out the CCD and sticking it under a SEM I’m going to be looking at tomorrow.<\/p>\n

Here’s the tube after pulling everything apart (teardown photos below):

The following diagram shows how the tube works, but check out the wikipedia page for more information<\/a>.<\/p>\n

Not exactly what I was looking for but an interesting find and the C-mount optics will be useful for another project. <\/p>\n
