content: Hi all,I have a Flir C2 and since it has MSX technology it's great........but it's not so great for close-up electronics work since at close distances the IR image and the MSX image are offset a tad.It's not so easy to manipulate one of the sensors so I thought about re-directing the light to the normal sensor........so I need to redirect it say 10 or 15 degrees, thus I need a small slither of wedge shaped glass this size that I could put infron of the sensor.....any idea?Ian.

content: While I haven't been using MSX for more than a year, thank you. A while ago I suggested to use some kind of shifted lens to fix parallax optically. But articulating the optical sensor and tilting it is a good solution in my mind as well. Maybe for their high end cameras a mechanism could do this with focussing automatically using activators or translating the focussing. The visual image has high enough resolution to be stretched a bit digitally.My idea for my bachelor's thesis still stands if making a realtime 3D reconstruction with visible/NIR cameras and projecting the thermal image to render out a high resolution image from a virtual camera position. But this simple approach is a good bit to explain the issue and current solutions.Great to see how the C2 looks on the side as well, I believe my CAT S60 will be similar and I need to open it soon.

content: The downside to adjusting the lens is that parallax error becomes more evident as you move closer or further away from the 6" distance per I had set during my modification.There is an "alignment adjustment" on the C2 itself, but it's minimum setting is 3ft.......and playing with it and another setting for "distance" under measurement parameters , both don't seem to do much at all, certainly not affecting parallax. Mine is an early C2......hmmm!It would be good to see Flir update their software/firmware to allow MSX distances right down to 6" and less..............for the electronics repair community!Ian.

content: The liberated E4 allows a parallax adjustment down to about 10cm.

content: Whilst I don't have a FLIR camera with MSX, I do have some interesting optical bits and pieces including a FLIR IR window thatmightjust serve as a thermal / (lossy) visible beam splitter. I'm also shortly expecting a LWIR/MWIR beamsplitter that may be persuadable to a similar purpose. It will be interesting to experiment. In an ideal world I'd like to be able to split LWIR-MWIR-NIR-vis-UV and see what I get; unfortunately I don't presently have a MWIR camera. Beamsplitters &c will doubtless be pretty lossy but fortunately visible light imaging devices are pretty sensitive these days.

content: Hello,as alternative to a hardware modification you can set this values in resource tree:.image.flow.visualZoom.factor 1.3682227.image.flow.visualZoom.xpanVal 16.image.flow.visualZoom.ypanVal -28but they will be reset on NUC.Not shure yet, but i believe you have to set this values in:\FlashFS\system\calib.rsc(dont forget the CRC32 value at the end)best regards

The hardware modification is insane and I would like to try your suggestion though, please, may you give me details on how I access these settings?Thank you.
