Can point matches focusable green laser refers to star pen

Green pen parameters [Material] copper [Dimension]: Diameter 13.5 × height 162mm [Appearance] pen-like [range]: [3000 meters] high-grade rubber exterior color black [gross weight] 59 g [packaging] paperback output modes: continuous straight line output, the output wavelength: 532 nm Output Power: 50mW Working Voltage: DC = 3V (7 AAA uses two AA batteries) Operating Current: I <450mA Warm-up time: None Operating temperature: + 20 ℃ ~ + 30 ℃ Storage temperature: + 10 ℃ ~ + 50 ℃ Power supply: two AAA batteries life: more than 5000 hours Features: laser tube + crystal + lens groups plush white packaging boxes (185 * 71 * 34) Color gift box (165 * 127 * 58) The new black plastic box (221 * 67 * 27) Features: 1, 2 laser power stability, beam quality, a good point to 3, compact structure and practical use of green pen: ◆ Use an object: 1. Field travelers / climbers / explorers ── for outdoor adventure, indicating distant targets and issued a distress signal. Let your trip more fun Interestingly, the preferred equipment for outdoor activities. 2. astronomer ── for astronomy refers to the stars, the green laser beam injection is a very beautiful green line. It is suitable for observing the stars at night, you can accurately indicate the position of the stars. 3. Mining field / construction personnel ── for remotely accurate indication / measurement of buildings can be avoided approaching the danger zone. Let you kilometers away like on-site command The military command or exercise: When you want to do your subordinates that you target in the air or in which direction the distant hillside, you also hand gestures desperately it? Of course not, you will be able to point to touch the sky green pen button, make your manners greatly increased. 5. Guide: for distant landscape instructions explain, no matter how much you behind the group, you can clearly see the point of interest. In addition to repair the site command and other emergency situations can also be used when the fire, floods, earthquakes and other description of the means star pen:! 10mw power green laser pointer, etc 20mw the following may be used in the field of light pollution small environment astronomical refers to the stars, but can not meet strong light pollution means the stars of the urban environment; 30mw above power green laser pointer is available for light pollution strong city environment refers to star; 50mw above power green laser pointer finger can be called a true star pen. [Note]: buyers do not necessarily read 1, at room temperature, you can begin to use up the brightest!! 2, laser harmful to the eyes, do not aim at eyes irradiation power over 30mw green pen, nor against human exposure, remember! 3. Keep the product away from children, to prevent the improper use of dangerous child. Best when not in use, remove the battery separately stored, so even children exposed to, because there was no battery also can not be used. 4, continuous light not more than 30 seconds, the green light filament consumption is relatively large, the power consumption is also more powerful, the proposed pro buy rechargeable batteries. 5, referring to the star pen laser generation medium is used in a variety of characteristics of the semiconductor, semiconductor, is very sensitive to temperature, at lower temperatures, the laser pointer can not work, then just hand over the laser pointer while, let the temperature rises above 20 degrees, the pen will be able to work it! Safety precautions: 1, hazard warning:! Laser harmful to the eyes, the extent of damage may cause vision loss or even blindness eye, do not front eye irradiation power over 30mw green pen, nor against human exposure, remember 2, management and use of green pen must be done by a professional (vocational) staff, untrained educators are not allowed to open the use of green pen, especially do not give children to play. 3, the use of green pen, laser highlights try to move within the range of the projection screen, the laser beam path should absolutely avoid standing or sitting when the normal eye sight. 4, to develop good habits green pens, please do not let go according to green pen when not indicated otherwise in the hands of perhaps unconscious movement will laser irradiation to the eyes of others. Focusable (match point) green pen Operation 1, installed two AAA batteries, the light mount lenses out loose until the O-ring is exposed so far. 2, press the button and watch the green light beam from the side, find the smallest beam (light exit from the position of about 4-6cm) and then match head placed in this (beam finest locations). 3, the lens out, the fine points of the beam near the optical port. 4, the laser eye hurt! Green eyes can not look directly at the light outlet! Nor will the green light outlet directed at people's eyes!
