20mW green laser pointers
The laser wavelength is 532 nm (green), has a continuous emission of radiation
The human eye is more sensitive to green light, so the laser pointer shines more than the red light allowing the air beam is visible in the dark or low light.
Also our green laser pointers have a power far greater than conventional red laser pointers.
It has great scope in the dark (1.5-2 km)
For astronomy or for applications requiring a highly visible beam, we recommend the 50mW model
