How to train a dog to use a laser pointer?
Summarize the practice by practicing with as many objects as possible, adjusting the collimator at greater and greater distances and in different environments. The object is not always his toy and does not necessarily lie on the ground. The change in situation is a key factor in the dog's learning process, helping to ensure that commands can be mastered in any situation. There are some precautionary calculations associated with the use of powerful green laser pointer that should be followed carefully. He gives them a lot of publicity, so these people will let you know how you feel. Due to Rayleigh scattering from air elements, higher power and higher frequency lasers (green or blue) can produce visible beams even in air, especially when observed in moderate to dim conditions. I have purchased several astronomical green lasers, which is a very cool bonus. The cave was investigated and is said to have been deformed by about 2. This is my weakest feeling: what I'm saying is not accurate. The point of this approach is that you can deliver the product to the customer without touching the problem.

Application
The low efficiency laser (power less than 0.4mW) will not exceed the MPE value under any conditions for both eyes and skin, even when focused through an optical system. You can ensure that your design is secure and you don't have to manage it. Typical applications include laser Pointers, CD players, CD-ROM hardware, geological exploration equipment, and laboratory analytical instruments. The visible high powered laser output is low (power 0.4MW-1MW), and the reaction time of eye closure is 0.25 seconds. In this case, the calculated exposure cannot exceed the value of MPE. Laser 1mW is usually less, will cause dizziness can not think, with one eye protection, can not be said to be completely certain, do not directly into the beam, do not use class II laser directly illuminate other people's eyes, avoid using observation equipment far laser CLASS II. Typical applications include classroom presentations, astronomical laser Pointers, rangefinder sights and equipment. III Continuous laser level visible, output 1-5MW laser beam, beam energy density is up to 25 W/m?? M. Avoid using IIIA laser observation devices far away, which may increase the risk. Typical applications IIIA and Class II phase have much in common, such as laser designators and laser scanners.
