Title: IR sensor from military camera
Post by: mikeselectricstuff on April 25, 2018, 10:08:39 am

This sensor is from a long-range military camera, 320x240.
Interesting baffle  arrangement inside, with what looks like carbon black coating inside.

No time to dig out the microscope atm - will post die pics later

Was it from a dead one of these? https://www.eevblog.com/forum/thermal-imaging/long-range-thermal-imaging-cameras-fs/ (https://www.eevblog.com/forum/thermal-imaging/long-range-thermal-imaging-cameras-fs/)

Now a very dead sensor :( Seeing a destroyed microbolometer always makes me feel sad. They are such expensive and well constructed devices.

That milspec 320 x 240 array cost the manufacturer of the camera around £11K. They are supposed to be high performance and robust but I see that some of your cameras have suffered dead pixels.

The format of the sensor is not uncommon and is a Honeywell derivative. ULIS used similar on one of its A-Si Microbolometers.

Mike,

I will happily buy any remaining parts of the camera that the dead microbolometer came from as spares for my two. The window in the front of the camera case would be especially useful as I need one for my M324L.
Let me know if you have them for sale please :)
