520nm 80mw Green Line Generator Laser Diode Module for Stone Wood Cutting Low Working Temp Osram LD in Dust-proof Water-proof

Specification:
1. Low Temperature turns on. This laser can work in winter for temperature at -25 centigrade
2. High temperature working: this laser can work on summer when the working temperature is over 40 centigrade. 
3. Dust/water-proof cover which will protect the laser when it cuts stones or woods. 
4. Bigger housing for longer duty cycle.
5. 12VDC adapter for more stable power supply

Comparing with 532nm laser modules, this one is better at those areas:
1. wider working temperatuer from -25~45 centigrade
2. stable wavelength, no red bomb. 
3. working in more seriously conditions.
