Removing lens of AMB86-MINI to remove IR filter and placing an IR cut filter

Technical Discussion
1

Hi. I’d like to make the AMB86-MINI night vision. I haven’t bought one yet, I wanna make sure first if it’s possible to make it night vision.

To make it night vision, I want to first remove its lens to remove the IR filter. Then, I’m gonna use a lens mount with an IR cut filter (similar to the image shown below) to be able to remove and place an IR filter on command. Lastly, I’m gonna reattach the lens on the mount.

My questions are:

  1. Is it possible to remove the lens of the AMB86-MINI? I can see from pictures and videos that there is some kind of hot glue attaching the lens to the camera. Is it safe to remove it? What method would you recommend to remove it?

  2. How big is the JX-F37 camera module attached to the AMB86-MINI? Can the lens fit in an M12 lens mount (like in the attached picture)? If not, how would you recommend attaching an IR cut filter to the camera?

  3. Can you do a tutorial on this?

I am currently working on this task. I have tested the lens with an adjustable focal length M12 interface and it has been tested to be feasible. Of course, a variable focus lens requires an infrared filter. I am trying to replace the lens holder of AMB82’s M12 interface with a glue remover, replacing it with an M14 directly inserted lens holder, and installing a lens that can be focused by a motor, including IR-CUT. If there is any progress, I will send it out to everyone to see.

I replaced the original lens holder with a glue remover and installed an IR-CUT and zoom lens. I manually adjusted the focal length and tested the actual image effect, as shown in the near and far focus images. I think there is basically no problem. I designed a circuit to drive the zoom lens and IR-CUT. When I get the circuit board, I will use the iIC of amb82 to drive the zoom and filter. What will be the actual test results.

Joined in here to tell you that this would be an amazing project.

Turn amb82-mini into vari-focal lense and then add auto focus to it.

Next I am searching for a decent 3d printed case for the same.

My plan is to use it as diy live stream recording camera for my tech YouTube channel and showcase it in my game play videos.

Will wait for more documentation on changing the lens and controlling the Motors for auto focus I doubt that it will be easy.

As long as manual focus through software is achievable then its all fine…

I found this issue on git which can be opened if you @ren_yucheng managed to get focal motor working.

Sorry for not replying for a long time. I would like to tell you that I have already implemented this zoom function, which is to use the IIC function of amb82 and a stepper motor control chip that communicates with IIC. The zoom effect looks good. I used the frame data from the object tracking algorithm routine to evaluate the depth of field and drive the optical zoom

This sounds amazing. Do you plan to document it ?

I have purchased a DSLR already to practice something but I am always looking to try new DIY solutions, though I know this cannot beat a DSLR performance but this can be a good project to showcase.

DIY camera with vari-focal lense and can be controlled from the firmware, maybe next step would be to add auto focus algorithm.

Thanks for the reply.
