I looked several years ago for the same thing and the issue I had was finding one to fit the USB-C port on our Motorola Z phone. I am sure they are available now but have not purchased one yet. There are lots to chose from on Amazon. Be aware of camera diameter, number of lights, cable length and flexibility. Also look at IR attachments. We used a Flir that went into a Apple phone at work that was incredible....but it was a FLIR I'm sure it was $$$.
