Quadrum Green: green laser technology
The distance at which a laser is visible to the naked eye depends on its colour
i.e. wavelength. This is because of the human eye's physiology – green
appears brighter to us than red. Depending on ambient light, green lasers
are therefore many times more visible than red lasers; in indoor areas this is
as much as 12 times brighter. This permits applications on dark surfaces, over
longer distances and work in very bright ambient light. A red laser with a 635
nm wavelength is used as a reference value for brightness differentiation.
In contrast to red lasers, green laser light can only be produced indirectly. This
is a source of potential characteristic fluctuations:
The optimal operating temperature is 20°C. Outside its operating tempera-
ture range of 0 – 40°C Quadrum Green is darker. IMPORTANT: Allow the
unit enough time to adapt to the ambient temperature before switching the
unit on.
Laser brightness may vary somewhat from one unit to another. This is a
natural phenomena and excluded from warranty claims.
Green Laser will only work with certain Receivers. The maximum range of
the Receiver is shorter, please refer to technical details.
