26100A 520nm 80mW Green Line Generator Laser Module Water Resistant
Specification:
Wavelength: 520nm±10nm
Output: 80mW
Dimension: 26*100mm
Working Voltage: 12VDC
Focal Length: 5-8m for stone cutting or wood cutting
Focusable: Yes
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℃.
2. Working in more seriously conditions.

The best working method is 8-12hrs conntinuously working and 5 minutes resting. the mount will help the laser be fixed on the wall and prolong the duty cycle to 16-18hrs. Otherwise the laser may be burnt. Please read the using tips on the back of the warranty card. We will not take any responsibility for the incorrect use.

Note:    
The modules are tested and the output power are measured by laser power meter before sending out.    
Please don't compare the power of this one with a none-measured laser.    
If you doubt the output, please have the laser you recieved checked by laser power meter.
