This is a stand-alone instrument with built-in computer, etc. We used it for a particular project (determining the beta-crystalline state of PVDF), then business took us in different directions and it has been sitting idle for a couple of years. When we turned it on to check it out we got the self-test screen shown here. We checked it out, and it seems that the Florida humidity was a little harsh for the KBr windows and the beam splitter. Everything else seems to work. We replaced the windows with new ones, and replaced the throw-away dessicant packs with bake-able ones, plus two spares for baking out while the others are in service. We never did find a beam-splitter though.
If you have or can find a beam splitter for this instrument replacement is actually quite simple, just a couple of screws and no way I can see to go seriously wrong. Assuming, of course, that you are moderately technically competent. I had it out with little trouble when I checked it out. You need to wear cotton gloves, though! Fingerprints on the beamsplitter are not a good idea.
