The Galileo is the latest in functionality, reliability and output power stability. The click-on, click-off switch allows hands-free operation and easy use when continuous operation is required. The miniature heat sink means that the output will not drop during long operating periods. A fresh, high-capacity single lithium battery will keep this unit running for up to 2 hours! The Galileo is ideal for alignment, astronomy, and all other continuous use applications.
All of Laserglow's green laser pointers are IR-filtered for safety and employ APC technology to maintain constant output power. APC (Automatic Power Control) is a system that uses an optical feedback loop to ensure stable laser output.
