This is a new Emerald Flash green diode laser, the type
that works so nicely for pointing out stars, satellites,
etc. in the night sky. The beam is far more visible than
a red diode laser because of the eye's high sensitivity
to this wavelength. Great for pointing to constellations,
Messier objects, iridium flares, or tracing the ecliptic.
A wonderful teaching tool. This pointer has been used
only for 2 or 3 minutes to verify high brightness and
proper functioning. Here are the specs:
