The green laser JD303 is a generic model of a powerful, rechargeable laser pointer with an adjustable focus and a green beam of 532 nm. It is often sold with a rechargeable 18650 lithium battery, a charger, and a key-activated safety lock.
Features and specifications
- Beam and wavelength: The JD303 produces a visible green beam with a wavelength of 532 nm. The green light is highly visible, especially in the dark.
- Adjustable focus: A key feature of this laser is the adjustable focus, which can change the size of the beam spot. Focusing the beam to a fine point at close range can be powerful enough to burn certain materials, like a match.
- Star caps: The laser typically comes with a removable "star cap" or "disco rotator." When attached, this cap diffracts the laser beam into multiple patterns, creating a dynamic visual effect for entertainment or parties.
- Power: Different retailers list various power outputs, ranging from 30mW to 1000mW or more. Be aware that some listed power outputs may be exaggerated.
- Safety features: The device includes a safety lock, typically requiring a key to activate and operate. This is a critical feature, given the laser's high power.
- Battery: The JD303 is powered by a rechargeable 18650 lithium-ion battery.
- Applications: Common uses for the JD303 include stargazing, presentations, camping, hiking, and as a signaling device.
Safety considerations
- Eye hazard: The JD303 is not a toy. It is a high-power laser that can cause permanent eye damage with direct exposure. It should be kept out of reach of children.
- Overheating: The device should not be operated continuously for extended periods (typically more than 30 to 60 seconds), as this can cause the internal components to overheat and fail.
- Recalls: Some versions of the JD-303 have been subject to product recalls due to safety concerns and mislabeling of power class. It is important to treat any JD303 with extreme caution.
