Laser characteristics:
Laser and ordinary light are electromagnetic waves, their transmission speed is 300,000 kilometers per second, but laser has its own unique physical properties:
1. Monochrome is good. The wavelength of laser is very consistent. The difference of the wavelength of his beam is only one-tenth of a million or less. It is a kind of light with excellent monochromaticity.
2. High brightness
3. good directionality, very concentrated light, the divergence angle of the beam is several thousand times smaller than the searchlight
Blue laser
Wavelength: 405nm
feature: high-end, laser Pen Ultimate Players Will Choose Blu-ray Pen,The risk to the eyes is high.
Green laser
Wavelength: 532nm
feature: Small disturbance and high sensitivity, trajectories can be captured when the light source is dim, especially when illuminating the sky at night.
Red laser
Wavelength: 650nm
feature: cheaper, In electronic teaching, presentations and presentations, red laser
