■ Visibility Curve
Green is closer to the center of the visibility curve,
so it's easier for human eyes to perceive. A green
laser looks as much as 8 times brighter than red.
A green laser is much more suitable for
presentations.
■ IC control device
The laser control function incorporates automatic
power control (APC). The APC prevents the laser
from over-heating and is used to regulate the laser
output. APC will maintain the laser constantly until
the batteries die and it won't hurt the laser at all.
APC maintains a constant output power until the
batteries die, thus eliminating the annoying power
variations in brightness resulting from thermal
effects on the diode and laser crystals as the pointer
heats up.
