Instruction:

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

NOTE:

• The laser can be bright enough when you light it in normal temperature, so you had better not light it continually over 30 seconds
• When not using it, please take off the battery from the laser in order to avoid causing damage
• In some countries these laser pointers (especially the higher powered ones) may be illegal to own and/or use. Therefore, YOU (the customer) should accept all responsiblity and liability to determine and fulfill the requirements and limitations of use or resale of these products in accordance with your country's laws and regulations. In the event of resale, you also need to agree to incorporate this notation in the product description so that any potential buyer can be well informed before making purchasing decision

Safety Considerations:

Laser pointers are effective tools when used properly. The following considerations should be observed when using laser pointers:

• Never look directly into the laser beam.
• Never point a laser beam at a person.
• Do not aim the laser at reflective surfaces.
• Never view a laser pointer using an optical instrument, such as binocular or a microscope.
• Do not allow children to use laser pointers unless under the supervision of an adult.

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.

Package Included:

• 1 x 100mW Handheld Green Laser Pointer
• 1 x 18650 Battery
