Dimensions: 12x38mm( without PCB circuit size)
Output Wavelength: 532nm (+-10nm)
Power : Laser Shape: LINE
Beam Divergency: Shell material: Brass
Circuit Control: ACC line
Reverse Polarity Protection: Yes
Working Voltage: DC = 3.7V
Working Current: I Warm-up time: None
Operating temperature: 0°C ; ~ +40°C;

Note:
532nm Green Laser is made by 808nm Laser Diode plus Crystal lens to transfer Green Light, it needs preheat 2-5seconds under 10 °C.
In lower temperature when Green Light is weak at beginning,after preheat it will turn bright .It is normal.
