安东帕旋光仪是(shi)测定旋(xuan)(xuan)(xuan)(xuan)光(guang)(guang)性(xing)物(wu)(wu)资(zi)(zi)旋(xuan)(xuan)(xuan)(xuan)光(guang)(guang)度(du)(du)的(de)仪器(qi)。经(jing)由过(guo)程对(dui)样品旋(xuan)(xuan)(xuan)(xuan)光(guang)(guang)度(du)(du)的(de)丈(zhang)量，能(neng)够阐(chan)发(fa)肯定物(wu)(wu)资(zi)(zi)的(de)浓度(du)(du)、含(han)量及(ji)纯度(du)(du)等(deng)。天然光(guang)(guang)经(jing)由过(guo)程起偏(pian)(pian)镜后发(fa)生立体偏(pian)(pian)振(zhen)(zhen)光(guang)(guang)，若是(shi)旋(xuan)(xuan)(xuan)(xuan)光(guang)(guang)管中艳服的(de)为旋(xuan)(xuan)(xuan)(xuan)光(guang)(guang)性(xing)物(wu)(wu)资(zi)(zi)，当(dang)偏(pian)(pian)振(zhen)(zhen)光(guang)(guang)经(jing)由过(guo)程该物(wu)(wu)资(zi)(zi)溶(rong)液(ye)时(shi)，偏(pian)(pian)振(zhen)(zhen)光(guang)(guang)的(de)角度(du)(du)会向左或向右扭转(zhuan)(zhuan)一(yi)定角度(du)(du)，这时(shi)候，为了让扭转(zhuan)(zhuan)一(yi)定角度(✃du)(du)后的(de)偏(pian)(pian)振(zhen)(zhen)光(guang)(guang)能(neng)经(jing)由过(guo)程检(jian)偏(pian)(pian)镜光(guang)(guang)栅，须要将检(jian)偏(pian)(pian)镜扭转(zhuan)(zhuan)一(yi)定角度(du)(du)，在目镜处能(neng)力看(kan)到敞(chang)亮。这个(ge)所扭转(zhuan)(zhuan)的(de)角度(du)(du)便(bian)是(shi)该待测物(wu)(wu)资(zi)(zi)溶(rong)液(ye)的(de)旋(xuan)(xuan)(xuan)(xuan)光(guang)(guang)度(du)(du)
