Some discontinued medical machinery from Invivo, a pcb with some sensors on it "ANESTHETIC AGENT ANALYZER MODULE II"
It has this custom assembly of an IR lamp with a reflector, a flow cell and a phododiode array (presumably)
12 pin part. scratched markings that read "3-8-1B-15"
Would like to find out about this sensor and if it could be used in some diy spectropraphy spectrometry project.
On the photos, the full pcb.
Disassembled module, ir lamp is a ceramic rod with a conical reflector, the flow cell in center and the presumed photodiode array on the right with a split window, spacers and module plate.
