Technical Features of Laser Pointers
Laser pointers operate on the principle of stimulated emission of radiation, producing a highly concentrated beam of light. Key technical features significantly impact performance and application. These features are often detailed on e-commerce sites like www.tradewheel.com and www.laserpointerstore.com, enabling consumers to compare products effectively. The following table summarizes these key characteristics:
| Feature | Description | Significance |
|---|---|---|
| Wavelength (nm) | The color of the laser beam; determines its visibility and applications. | Different wavelengths have varying levels of visibility and power capabilities. |
| Output Power (mW) | The amount of power emitted by the laser; influences beam brightness and range. | Higher power lasers are brighter and have a longer range, but pose safety risks. |
| Beam Divergence | The spread of the laser beam; affects the size of the spot at a distance. | Lower divergence results in a tighter, more focused beam over longer distances. |
| Focusability | The ability to adjust the beam’s focus; impacts spot size and intensity. | Adjustable focus allows for versatility in applications, from pinpoint accuracy to broader illumination. |
| Battery Type | The type of battery powering the laser; affects runtime and availability. | Different battery types offer varying runtimes and charging options. |
| Safety Class | A classification based on the laser’s potential hazard to the eye; dictates safe operating procedures. | Understanding safety classes is crucial for responsible laser use. |
Types of Laser Pointers
The market offers a wide variety of laser pointers, each designed for specific purposes. Platforms like www.dhgate.com provide a broad selection, while sites like oxlasers.en.ec21.com specialize in particular types. The distinctions between these types are crucial for selecting the appropriate device:
| Type | Description | Applications |
