Flir E4 Thermal imaging camera teardown
De:
Is there any way to improve the E8 is one already has the original e8? Like adding wifi or bluetooth..
0-8-15 User:
I'm thinking of modifying my Flir E4 for some close-up shots, but I don't have a 3D printer or any idea which lens to use. What's the best way to go about it?
Bud:
You'd need a lens holder anyways and those are usually custom 3D printed. A few lens holder models were shared in this thread but you should be able locate them on the usual 3D printing sites like Thingiverse and such.
For a lense itself people typically use ZnSe lenses for laser engravers/cutters available from eBay or Ali. You pick one with a focal distance you need and the diameter matching the lens holder lens cavity.

Hey Bud, I was wondering if you could share your insight on a whole other E4 lens modification:
I am trying to adapt my E4 to function as a nocturnal wildlife camera, and obviously macro wouldn't work, so I want to create a telephoto solution.
As you know, the ZnSe ali/ebay options are easy and relatively cheap. (And after some rigorous searching it seems in general the converging (plano-convex) lenses are most affordable. Making a simple telephoto converter with these lenses is relatively easy.
(In theory I have not tested anything yet and can't comment on light transmission, sharpness and distortion.)
With a front lens of f100 and a back f25 this will produce 4x enlargement.
As an unfortunate unwanted side effect it will also invert the image on the sensor, and on the screen, mirroring left/right, which is a pita.
Could this be solved in the hacked E4 software? Or is this way to far fetched?
I have decompiled facet.rcc and combed through the *.qml files.
With rcc extended explained in post https://www.eevblog.com/forum/thermal-imaging/flir-e4-wifi-resolution-and-menu-hack-thread/msg3364376/#msg3364376
I was actually looking for two things:
1, A way to turn down the screen brightness of the E4 even further, so it is better at night.
There is a ui model "deviceSettingsModel" with "ID_SETUP_DISPLAY_INTENSITY" and "displayIntensitySettingsModel" with ui_model_item "ID_SETUP_LOW" in design_ui.xml, but I am not smart enough to figure where it takes values from.
2, Any hint or way to mirror the image.

I'd be inclined to try to get the original lens out of the E4 and just use a new main objective. You would be using the centre of the image so it should not be too bad.
See some of the results in the 'F1G2 lens' thread

(there is more to come - but work is needed on a broken connector and holding a REALLY BIG :scared: lens)
