ronit 100 continuous zoom thermal lens with bae systems core project

[strykir]

Hello,

I started working on a custom thermal drone project a few months ago with the idea that it would have a compact and high-performance thermal camera set up. Slowly I have been gathering the necessary parts to build the drone. Today however, I received one of the most important parts of the entire project, which is the continuous zoom lens. before I bought this lens, I was talking to a few companies on alibaba about purchasing a zoom lens, but in the end I didn't go with them because of the long lead times, and because the model I was interested in was a bit too expensive for me to not know what the quality would end up being like after waiting so long. by chance I came across this lens at a pretty good price. ended up buying it immediately.  The seller advised me not to communicate with the manufacture as they want to keep all the info restricted. On the contrary, when dealing with the Chinese companies on alibaba, they provided me with cad models and even detailed pdfs for the thermal cores and lenses.

I have a couple different options available for the thermal core, including a reap ir, though id prefer to find a loose bae systems thermal core rather than tearing the reap ir apart.

Right now Im using chat gpt to try and figure out how to get this thing working, and Im making some progress. I saw there was another guy here who had the same lens and was trying to figure out how to get it working but he stopped posting.

Im keen on getting this thing working. Ill try to post some more info as things develop.

I got the same lens you got, i put a post call out for helping to identify the four wires.   the brown and blue paired and twisted together and the green and orange paired and twisted together. I think these are the four wires used for rs422 control of the lens. also, there are three wires black-white-yellow paired together do not know what they are for, try using a usb to rs422 adaptor to control the lens but i do not know wish hole the put each of the four wires in because the lens has no indications on the pc board. don't want to damage the circuits, put power to the black and red wires and the lens goes into a self-test and stops in the 15mm wide angle position, this allowed me to put a flir tau2 core to the proper back focus point. then i manually rotated the zoom motor to 100mm the lens maintained focus for 15mm to 100mm.im sending you my pictures of how the wires are paired up, how the colors go to lens connector  and picture of the usb adaptor with pinout info. the flir tua2 picture shows that I just used the lens retaining ring from the flir camera to keep the camera flat and not tilted to the lens. if you know where each of the four control wires go to the adaptor i will help me and others with the same lens. i hope my pictures get you started. good luck
