安东帕旋光仪是测(ce)定(ding)旋(xuan)光(guang)(guang)(guang)(guang)性物资(zi)旋(xuan)光(guang)(guang)(guang)(guang)度(du)的仪器。经由(you)(you)过(guo)程(cheng)(cheng)对样品旋(xuan)光(guang)(guang)(guang)(guang)度(du)的丈量，能(neng)够阐发(fa)肯定(ding)物资(zi)的浓(nong)度(du)、含(han)量及纯度(du)等。天然(ran)光(guang)(guang)(guang)(guang)经由(you)(you)过(guo)程(cheng)(cheng)起(qi)偏(pian)(pian)镜(jing)后发(fa)生(sheng)立体偏(pian)(pian)振(zhen)(zhen)光(guang)(guang)(guang)(guang)，若是旋(xuan)光(guang)(guang)(guang)(guang)管(guan)中(zhong)艳服的为旋(xuan)光(guang)(guang)(guang)(guang)性物资(zi)，当偏(pian)(pian)振(zhen)(zhen)光(guang)(guang)(guang)(guang)经由(you)(you)过(guo)程(cheng)(cheng)该物资(zi)溶(rong)液时，偏(pian)(pian)振(zhen)(zhen)光(guang)(guang)(guang)(guang)的角(jiao)(jiao)度(du)会(hui)向(xiang)左或(huo)向(xiang)右扭(niu)(niu)转一定(ding)角(jiao)(jiao)度(du)，这时候，为了让扭(niu)(niu)转一定(ding)角(jiao)(jiao)度(du)后的偏(pian)(pian)振(zhen)(zhen)光(guang)(guang)(guang)(guang)能(neng)经由(you)(you)过(guo)程(cheng)(cheng)检(jian)偏(pian)(pian)镜(jing)光(guang)(guang)(guang)(guang)栅，须要将(jiꦐang)检(jian)偏(pian)(pian)镜(jing)扭(niu)(niu)转一定(ding)角(jiao)(jiao)度(du)，在目镜(jing🦄)处能(neng)力(li)看(kan)到敞亮。这个(ge)所扭(niu)(niu)转的角(jiao)(jiao)度(du)便是该待(dai)测(ce)物资(zi)溶(rong)液的旋(xuan)光(guang)(guang)(guang)(guang)度(du)
