Introduction and Application

A laser pointer or laser pen is a portable and visible laser. It is designed to highlight something of interest by projecting a small bright spot of colored light onto it. 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 project a visible beam via scattering from dust particles or water/fog droplets along the beam path. Higher power and higher frequency lasers may have a visible beam even in clean air due to Rayleigh scattering from air molecules, especially when viewed in moderately-to-dimly lit conditions. The intensity of such scattering increases when these beams are viewed from angles near the beam axis. Such pointers, particularly in the green-light output range, are used as astronomical-object pointers for teaching purposes, in the same general manner as flashlights..

Laser is harmful to human's eyes, so please do not expose the laser beam directly to human eyes. Please keep it away from children's store in order to avoid any accident. If use in the wrong way and get hurt or damaged, the user should take the full responsibility.

NOTE from China365mall Sale Department:

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 laser pointer is in use, taking off battery can cause damage. 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 need to agree to incorporate this notation in the product description, so that any potential buyer can be well informed before making purchasing decision

Regulations and Misuse:

Laser pointers are good tools only when used properly. When using laser pointers, the below must be observed:

Never point a laser beam at a person
Never look directly into the laser beam.
Do not aim laser at any reflective surfaces.
Never view a laser beam using an optical instrument, such as binoculars or microscopes.
Children are not allowed to use laser pointers unless under the supervision of an adult.
Use only laser pointers meeting the below 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 safer.
