The Laser 303 Red Laser Pointer projects a 650 nm beam across distances up to 2000 meters. Using a 3.7V DC power source, it maintains a continuous red line for optical experiments or pointing. Physical safety keys lock the rear circuit to prevent unauthorized battery activation.
Key Features
- Adjustable Focus: Rotating head mechanism changes beam thickness and spot size. Helps pinpoint targets at varying distances.
- Safety Key Lock: Mechanical rear lock requires physical keys for circuit completion. Stops accidental battery drain or misuse.
- Aluminum Alloy Body: Aviation-grade metal casing provides high impact resistance. Survives drops and heavy road dust exposure.
- Rechargeable 18650 Cell: High-capacity 3.7V Li-ion battery powers the internal diode. Fits external charging docks for reuse.
Frequently Asked Questions
Is Laser 303 red laser powerful enough to burn?
This 650nm red laser lacks the thermal output to ignite matches. It serves visual pointing and presentation needs only.
How to charge Laser 303 battery?
The 18650 Li-ion battery requires an external wall-socket charger. You must remove the cell from the laser body to charge it.
