\n\nقسمت ها و تکه های اتفاقی از فایل\n\n \n\nGenerally one can state that a laser is more dangerous with:\n\n(i) Higher power\n\nHigher intensty means more power per time that can cause damage when the light is absorbed\n\n(ii) Less visibility of its wavelength\n\nInfrared and ultraviolet light will not cause the blinking reflex (aversion response)of the human eye, This means the retina will be exposed longer and the damagewill therefore be greater\n\n(iii) Higher intensity (stronger focus of the light)\n\nStronger focus means more power per area which means that the damage may be more but at the same time worse.\n\n \n\nWhat you need to know (with regard to safety) about the lasers used in the Modern Optics Lab:\n\nThroughout the Modern Optics Lab, several laser types are used. All of them are visible and all will have power between 1mW and 4mW (class IIIa).\n\nWhat you need to know (with regard to safety) about the lasers used in the Modern Optics Lab:\n\nProtective eye wear is not required and burns of the skin are impossible as long as these lasers are not focused;\n\nHowever: Be aware that when these lasers are handled inappropriately (by violation of the following safety rules), severe eye damage can occur nevertheless!\n\n \n\nModern Optics Lab Safety Rules\n\nThe lasers for the experiments will be installed in the experimental setup such that no direct exposure of the eye will be possible during operation of the lab. Do not change these setups especially do not move the lasers, do not take them out of their holders, do not take optical elements (mirrors, detectors, beam expanders etc.) out of setups UNLESS the lab procedure requires you to do so. If this is the case, turn off the laser before you do this or use a safe shutter to prevent any laser light emission or block the laser light with a paper shield.\n\nWhen the LASERS are turned on, do not have your eyes on the level of the optical path of the laser beam. Your eyes may be exposed to the laser if an optical element is misaligned.\n\nDo not put anything that has a reflecting surface (screw drivers, mirrors or other metallic objects) into the optical path of the laser beam. The beam may get reflected into your eyes.\n\nNever reflect the laser beam out of an experiment, especially not toward your face or the face of other persons.\n\nIn the unlikely case of an accident resulting in an eye exposure with laser light which causes a visual effect that does not stop after the laboratory.\n\n \n\n \n\n30 تا 70 درصد پروژه | پاورپوینت | سمینار | طرح های کارآفرینی و توجیهی | پایان-نامه | پی دی اف مقاله ( کتاب ) | نقشه | پلان طراحی | های آماده به صورت رایگان میباشد ( word | pdf | docx | doc )
