Green laser pointer is now the world s most popular laser pointers because the green lasers than red lasers 6 times more than red laser beam significantly while the price is much cheaper than the blue and yellow.
Powerful red laser pointer pen beam light 5mw.
We suggest the continuous illumining use should be less than 1 minute in case of the excessive heat influence the service life.
Green pen is the wavelength of light emitted 500 550nm the wavelength sensitivity of the coefficient table as is the closest one wavelength.
Green pen is the wavelength of light emitted 500 550nm the wavelength sensitivity of the coefficient table as is the closest one wavelength.
This 5mw 650nm ultra powerful beam light red laser pointer is small and exquisite portable and with richer applications.
