安东帕旋光仪是测(ce)定旋(xuan)(xuan)光(guang)(guang)(guang)(guang)性物(wu)资(zi)旋(xuan)(xuan)光(guang)(guang)(guang)(guang)度的(de)(de)仪器。经由(you)过(guo)(guo)程对样品旋(xuan)(xuan)光(guang)(guang)(guang)(guang)度的(de)(de)丈(zhang)量，能够阐发肯定物(wu)资(zi)的(de)(de)浓度、含量及纯度等。天然(ran)光(guang)(guang)(guang)(guang)经由(you)过(guo)(guo)程起偏(pian)(pian)(pian)镜后发生立(li)体偏(pian)(pian)(pian)振光(guang)(guang)(guang)(guang)，若是旋(xuan)(xuan)光(guang)(guang)(guang)(gua🦋ng)管(guan)中(zhong)艳服的(de)(de)为(wei)旋(xuan)(xuan)光(guang)(guang)(guang)(guang)性物(wu)资(zi)，当偏(pian)(pian)(pian)振光(guang)(guang)(guang)(guang)经由(you)过(guo)(guo)程该物(wu)资(zi)溶液(ye)(ye)时，偏(pian)(pian)(pian)振光(guang)(guang)(guang)(guang)的(de)(de)角(jiao)度会向(xiang)左(zuo)或向(xiang)右扭(niu)转(zhuan)(zhuan)一定角(jiao)度，这(zhei)时候(hou)，为(wei)了让扭(niu)转(zhuan)(zhuan)一定角(jiao)度后的(de)(de)偏(pian)(pian)(pian)振光(guang)(guang)(guang)(guang)能经由(you)过(guo)(guo)程检偏(pian)(pian)(pian)镜光(guang)(guang)(guang)(guang)栅(zha)，须(xu)要(yao)将检偏(pian)(pian)(pian)镜扭(niu)转(zhuan)(zhuan)一定角(jiao)度，在目镜处能力看到敞亮。这(zhei)个所扭(niu)转(zhuan)(zhuan)的(de)(de)角(jiao)度便(bian)是该待测(ce)物(wu)资(zi)溶液(ye)(ye)的(de)(de)旋(xuan)(xuan)光(guang)(guang)(guang)(guang)度
