安东帕旋光仪是测(ce)定(ding)(ding)旋(xuan)(xuan)光(guang)(guang)(guang)(guang)性物(wu)(wu)资(zi)旋(xuan)(xuan)🎉光(guang)(guang)(guang)(guang)度(du)(du)的仪器。经由过(guo)程对样品旋(xuan)(xuan)光(guang)(guang)(guang)(guang)度(du)(du)的丈量(liang)，能(neng)够阐发肯定(ding)(ding)物(wu)(wu)资(zi)的浓度(du)(du)、含量(liang)及纯度(du)(du)等。天然光(guang)(guang)(guang)(guang)经由过(guo)程起偏(pian)(pian)(pian)镜后发生立体(ti)偏(pian)(pian)(pian)振(zhen)(zhen)光(guang)(guang)(guang)(guang)，若是旋(xuan)(xuan)光(guang)(guang)(guang)(guang)管中艳(yan)服(fu)的为旋(xuan)(xuan)光(guang)(guang)(guang)(guang)性物(wu)(wu)资(zi)，当偏(pian)(pian)(pian)振(zhen)(zhen)光(guang)(guang)(guang)(guang)经由过(guo)程该物(wu)(wu)资(zi)溶液时(shi)，偏(pian)(pian)(pian)振(zhen)(zhen)光(guang)(guang)(guang)(guang)的角(jiao)(jiao)度(du)(du)会向(xiang)左或向(xiang)右扭转一(yi)定(ding)(ding)角(jiao)(jiao)度(du)(du)，这时(shi)候(hou)，为了让扭转一(yi)定(ding)(ding)角(jiao)(jiao)度(du)(du)后的偏(pian)(pian)(pian)振(zhen)(zhen)光(guang)(guang)(guang)(guang)能(neng)经由过(guo)程检(jian)偏(pian)(pian)(pian)镜光(guang)(guang)(guang)(guang)栅，须(xu)要将(jiang)检(jian)偏(pian)(pian)(pian)镜扭转一(yi)定(ding)(ding)角(jiao)(jiao)度(du)(du)，在目镜处(chu)能(neng)力看到敞亮。这个所扭转的角(jiao)(jiao)度(du)(du)便是该待测(ce)物(wu)(wu)资(zi)溶液的旋(xuan)(xuan)光(guang)(guang)(guang)(guang)度(du)(du)
