Laser Safety Guidelines:

• Never point your laser at another person, especially their face or eyes.
• You'd better not look directly into the laser beam. Even if it is a low powered laser, it will be damaging if you stare at it for quite a while.
• Always be conscious of and aware of reflective surfaces such as mirrors, polished metal or glass. A reflected beam can also harm your eyes.
• Only use a high powered infrared laser in a controlled environment.
• Do not let other people, esp. kids, use your laser unless they are fully aware of the dangers of lasers.
• Laser beams can go for miles so never randomly use your laser outside.
• Wear laser safety glasses if you are using your high power laser for dangerous applications.

Instructions:

A laser pointer is a small laser designed to highlight something of interest by projecting a small bright spot of colored light onto it. The laser beam is not in itself visible from the side, but is visible as a result of light scattered by dust particles along the beam path. The small width of the beam and low power of typical laser pointers make the beam itself invisible in a reasonably clean atmosphere, showing a point of light when striking an opaque surface. Some higher powered laser pointers are faintly visible via Rayleigh scattering when viewed from the side in moderately or dimly lit conditions.

Use only laser pointers meeting the following criteria:

• Labeled with FDA certification stating "DANGER: Laser Radiation" for Class 3R lasers or "CAUTION: Laser Radiation" for Class 2 pointers.
• Classified as Class 2 or 3R according to the label. Do not use Class 3b or 4 products.
• Operate at a wavelength between 630 nm and 680 nm.
• Have a maximum output less than 5 mW, the lower the better.

Warning:

• Laser is harmful to human's eyes, so please don't expose the laser directly to human eyes. Please keep it away from children's store in order to avoid any accident. If get hurt or damaged due to private incorrect method, the user would take the full responsibility
