Topdon TC001 and TC002 thermal camera lens mount
Rasperry pi, left: with macro lens 76.2mm, right: without (both images scaled and cropped to show the approx. the same excerpt. The closest distance where the image was as sharp as possible was chosen each)
- Allows for mounting a PVD lens with a diameter of 20mm
- Focal distance can be varied by a thread
- A ¼" camera mount allows for a tripod attachment
- Inspired by https://youtu.be/wG1JiTR00H8
- Have a look here for using the camera at a computer: https://github.com/leswright1977/PyThermalCamera/
Lenses:
- You need special lenses that are transparent for infrared radiation
- A focal length of 76.2 mm is known to work for macro imaging (see comparison image)
- You can get a lens here: https://www.aliexpress.com/item/1005005426131784.html , choose 20mm diameter and e.g. 76.2 mm focal length USA ZnSe or China PVD
Printing:
- Print all three parts
- 3 Perimeters
- I used ASA for long lasting “springy” elements, but PLA and PETG were reported to work well, too.
- Clearances are a thing here, so have your printer tuned in
- Freecad file is attached, you can relatively easy change dimensions.
- The middle tube snaps into the enclosure part.
- Snap the lens into the lens tube.
- Screw the lens tube into the middle tube.
