How Do You Choose A Green Laser Pointer?
• Watch the light spot in a dark place, and if there is an obvious flood of light around the light spot, it may be a defective one. • See whether the light spot is a perfect solid dot. • Carefully see whether the light intensity is uneven, the light turns on and off automatically, or is irregular when the laser beam shines. If it is, there may be something wrong with the LD. If it’s one of the low power (below 20mw) lasers, you need to watch whether the light turns from dark color to brightened color. If it does, there may be something wrong with the circuit or LD of this laser pointer.
