Characteristics of 405nm Lasers
Color
The laser spot of a 405nm laser is purple. However, its beam is usually invisible.
Power Range
The highest power for a 405nm laser pointer usually does not exceed 2W. If you need high safety, please choose the power range of 1-50mW. If you need to burn something with a 405nm laser, please choose the power range of 1-2W.
Applications
Although the visibility of 405nm lasers is very low, they play an important role in specific fields. They are widely used in biological detection, laser engraving, laser experiments, etc.
