Unlimited Duration
All Jasper lasers measure actual laser beam power 30,000 times per second. If the beam is too strong, electrical power is reduced. Too weak a beam causes electrical power to increase. Called Automatic Power Control (APC), this process ensures a consistently bright, reliable beam. Other lasers use less efficient, technology and can operate for only a minute or two at a time before they must be turned off to cool. Failure to do so destroys the laser.

Thanks to APC, Jasper lasers require no cooling period. Run your Jasper for hours at a time if you like.

Better Battery
Your Jasper will operate from 6 - 9 hours from a single lithium battery. Other lasers get only 2 - 3 hours from a pair of AAA batteries. Lithium batteries hold more energy and work better in cool weather too.

Guaranteed Power
For safety reasons, consumer lasers are limited in output power. Called Class IIIa by the United States FDA, consumer lasers cannot exceed 5mw of beam power.

Many lasers cannot deliver the full measure of allowable power and often produce as little as only 1mw or 2mw. Jasper lasers are designed for maximum output. Each Jasper is tested immediately before shipment to ensure a beam power of at least 4mw under normal operating conditions.

Some companies claim to "tune" their lasers at 4.99mw but it is largely a wasted effort. Consumer lasers cannot hold such precision and their power fluctuates considerably with variations in battery voltage and temperature.

How it Works
A powerful lithium battery supplies electrical energy to the infrared laser diode. Focusing lenses direct the infrared beam into a pair of exotic crystals where it is transformed into streams of pure, emerald color. The expansion lens reforms the beam which then passes through a filter to remove any remaining infrared energy.

A splitter diverts a tiny portion of the beam to the Automatic Power Control system. APC compares actual beam strength to a reference value: Too strong and electrical power is reduced, too weak and power is increased. Adjustments are made 30,000 times every second, resulting in a beam of consistent power.

The lion's share of beam energy travels through the final collimating lens and leaps from Jasper's aluminum housing at 186,000 miles per second. When Jasper's light is beamed into the night sky, its photons will eventually travel over the full distance of our galaxy and beyond: truly a journey of eternity.
