@pomonabill221,
Sorry for the poor resolution that I have had to use. I am a little nervous of releasing ITAR covered technology internal images on the NET !
The item with the vacuum nipple is the fluorescent backlight for the EVF LCD.
If you would like to see pictures of the microbolometer board, I posted some decent resolution images here:
https://www.eevblog.com/forum/testgear/flir-e4-thermal-imaging-camera-review/msg307483/#msg307483The pictures of the microbolometer are from one of my PM570's but this is similar to the PM695.
The Generation 3 microbolometer in the 695 is traditional in that it is mounted on a thermoelectric (Peltier) element inside a vacuum chamber that is gold plated
The microbolometer and optics are large to provide decent sensitivity. The vacuum nipple is visible in the pictures. I believe teh microbolometer and large diamond turned Germanium optics were a significant cost on the BoM.
In the pictures I have shown only the CPU Board. Its pretty high density for the year it was built but easily worked on with the correct tools. It is a combination of MC68340 CPU and several Altera FPA's.
There is a pretty complex power supply PCB that sits on top of the CPU board and a video processing PCB that is as large as the CPU board and has its own CPU , Video RAM and and three huge 340 pin Altera FPA's !
The E4 is an example of the VLSI that has reduced the component count in modern TIC's. It is interesting that the modern FLIR industrial TIC's are still built in a metal shell with several PCB's and lots of chips ! Industrial and consumer TICs are two separate divisions inside FLIR.
