Hello
I want to show this little 532nm green DPSS module. I bought it from Fasttech for $9.87. That includes the 5% coupon. Use "BLF" for a 5% discount on light and battery products. Here is a link, $10.39 50mW 532nm Green Laser Module - 3V, 11.9mm at FastTech - Worldwide Free Shipping
Today I got the module and put it on test. Out of the box it does 82mW at 380mA/3V input
After some testing I decided go to the 100mW mark.
The result is 107mW at 414mA/3V input. The brass module was held in a large aluminium heatsink. The pot is very sensitive. Only a very light touch is enough to bump tens of mA.
This module can be easily build in a 12mm heatsink. The module has no IR filter. I took also a measurement with an external IR filter.
The dot is clean and nice round. It is right collimated at the infinity.
For $10 it is quite a bargain.
Note: I bought this module with my own money. No Fasttech people was involved.
