详细内容 Thisset-up mainlyconsists of laser tube,demonstration screen( withgraduated circle and grid lines) and other optical parts. Laser tubeis controlled by the separate switch and attached with strong magnet ,which can freely slide on the circle of the screen. Therefore ,the beam can rotate in a complete circle around the graduated plateand acquire any light ray or ray group required in the experiment. With a graduated circle on the demonstration screen , the angle of the incident ray and exit ray can be directly read. Inserted in strong magnet sheets , optical parts can move freely on thegraduated plate,which is available for flexible choice as you want or combine optical components, making the experiment more varied 1)Componentsseparate diode laser (3×)graduated diskpower supply three separate switchessemi-cylindrical lensdiffuse reflector plain -concave lensplain mirrow biconvex lens sector optical screen plain convex lensperiscopebiconcave lens bi-mirrorconcave-convex reflective glassglass optical fiberright angle prism demo screen for light pathequilateral prism parallel plates 2)Component data Item :laser moduleType : D1540Working Voltage DC35VWorking Current d65mAWorking Mode:consistent length of laser wave:635nmPower of laser tube 10mWMaterials of lens:optical glassstability of power d1working hourse5000hworking temperature:-10+50storage temperature -20+85laser light shape : dot size of laser light shape : 5*1.5mm@6cm divergence of beam : d0.2 mardoutline size : 15*40mm the length of lead line 165mmremark : the quality of line is stable 联系方式 Email caryun@ms37.hinet.net 公司名 JAYA LEE 国家 韩国 联系人 CHOI.
