Wavelength: 405nm Colour:violet Power:100mw Voltage:3.0V Current:250mA Diam:52mm*13mm Beam diligence:<5° Temp:10℃-40℃ Working time:less than 2 mins; if add cooling system,can be work
more than 1 hour each time. The violet laser module is a kind of industrial semi-finished
products,can be apply to many areas.The light is straight,long
distance and thin.So it is able to do many many jobs,for
example,pointing,guides,teaching,and so on. For customes’
convinence,we usually connect two lines outside.The black line is
design to connect with the negative electrode “-”,the red line is
design to connect with the anode “+”.There is a press key on the
board,if you do not need to control on the board,we will short
circuit it,so you can add another key outside. Advantages: stable power,long working time. Warranty: we supply 6 months free warranty.however,the free
warranty is only for the problem raise by the product itself,not
suit the damage cost by Force. Warning: Do not put too high voltage on it,otherwise the module
will be burn and fail working. And do not try to adjust the adjustable resistance on the board to
change the current. Do not let it knock or collide violently with others. Make it away from the water,or any wet dirty environment. |
