安东帕旋光仪是测(ce)定(ding)旋(xuan)光(guang)(guang)(guang)(guang)性物资旋(xuan)光(guang)(guang)(guang)(guang)度(du)(du)(du)(du)的(de)仪器。经(jing)(jing)由过(guo)程对样品旋(xuan)光(guang)(guang)(guang)(guang)度(du)(du)(du)(du)的(de)丈量，能(neng)够阐(chan)发肯定(ding)物资的(de)浓度(du)(du)(du)(du)、含量及纯度(du)(du)(du)(du)等。天然光(guang)(guang)(guang)(guang)经(jing)(jing)由过(guo)程起偏(pian)(pian)(pian)镜(jing)后发生立体(ti)偏(pian)(pian)(pian)振(zhen)光(guang)(guang)(guang)(guang)，若是旋(xuan)光(guang)(guang)(guang)(guang)管中艳服(fu)的(de)为旋(xuan)光(guang)(guang)(guang)(guang)性物资，当偏(pian)(pian)(pian)振(zhen)光(guang)(guang)(guang)(guang)经(jing)(jing)由过(guo)程该(gai)物资溶液时，偏(pian)(pian)(pian)振(zhen)光(guang)(guang)(guang)(guang)的(de)角(jiao)度(du)(du)(du)(du)会向(xiang)(xiang)左(zuo)或(huo)向(xiang)(xiang)右扭(niu)转(zhuan)一定(ding)角(jiao)度(du)(du)(du)(du)，这(zhei)时候(hou)，为了让扭(niu)转(zhuan)一定(ding)角(jiao)度(du)(du)(du)(du)后的(de)偏(pian)(pian)(pian)振(zhen)光(guang)(guang)(guang)(guang🐲)能(neng)经(jing)(jing)由过(guo)程检偏(pian)(pian)(pian)镜(jing)光(guang)(guang)(guang)(guang)栅，须要将检偏(pian)(pian)(pian)镜(jing)扭(niu)转(zhuan)一定(ding)角(jiao)度(du)(du)(du)(du)，在(zai)目(mu)镜(jing)处能(neng)力(li)看到敞亮。这(zhei)个所扭(niu)转(zhuan)的(de)角(jiao)度(du)(du)(du)(du)便是该(gai)待测(ce)物资溶液的(de)旋(xuan)光(guang)(guang)(guang)(guang)度(du)(du)(du)(du)
