SOLD
I would like to sell my old 660 nm TTL module that i've found deep in my all kind of stuff.
It has a C mount diode and a HUGE output beam ~6x4mm
I didn't measure the divergence -if you need it i will calculate.
Doing around 400mW (my LPM has ± 10% accurate)
The On-Board mains PSU is not working so the driver needs external 5VDC at least 2A PSU!
