I bought a THOR ULTRA Laser Pointer before.
As a result of using it for a long time, the diode broke.
So I'm trying to add a new laser diode,
I don't know how to disassemble. Is there anyone who can explain in detail?
No,
Nobody on LPF has ever investigated disassembling that laser nor does anyone have experience doing so.
Not worth doing. Buy a new one,
They are on sale for $79 at https://laserpointerstore.com/products/thor-ultra-laser-pointer maybe ask them if they can repair yours.
Please stop posting the same question over and over again.
