安东帕旋光仪是(shi)测(ce)定(ding)(ding)旋(xuan)光(guang)(guang)(guang)性物(wu)资(zi)旋(xuan)光(guang)(guang)(guang)度(du)(du)(du)的(de)(de)仪器(qi)。经由过(guo)程(cheng)对样品旋(xuan)光(guang)(guang)(guang)度(du)(du)(du)的(de)(de)丈量，能够阐发(fa)肯定(ding)(ding)物(wu)资(zi)的(de)(de)浓度(du)(du)(du)、含量及(ji)纯度(du)(du)(du)等。天然光(guang)(guang)(guang)经由过(guo)程(cheng)起偏(pian)镜(jing)后(hou)发(fa)生立(li)体(ti)偏(pian)振(zhen)光(guang)(guang)(guang)，若是(shi)旋(xuan)光(guang)(guang)(guang)管中艳服的(de)(de)为旋(xuan)光(guang)(guang)(guang)性物(wu)资(zi)，当偏(pian)振(zhen)光(guang)(guang)(guang)经由过(guo)程(cheng)该(gai)物(wu)资(zi)溶(rong)液时，偏(pian)振(zhen)光(guang)(guang)(guang)的(de)(de)角(jiao)(jiao)度(du)(du)(du)会向左或向右扭转(zhuan)(zhuan)一(yi)(yi)定(ding)(ding)角(jiao)(jiao)度(du)(du)(du)，这(zhei)时候(hou)，为了(le)让扭转(z🦩huan)(zhuan)一(yi)(yi)定(ding)(ding)角(jiao)(jiao)度(du)(du)(du)后(hou)的(de)(de)偏(pian)振(zhen)光(guang)(guang)(guang)能经由过(guo)程(cheng)检偏(pian)镜(jing)光(guang)(guang)(guang)栅(zha)，须要将检偏(pian)镜(jing)扭转(zhuan)(zhuan)一(yi)(yi)定(ding)(ding)角(jiao)(jiao)度(du)(du)(du)，在目(mu)镜(jing)处能力看到敞亮。这(zhei)个所扭转(zhuan)(zhuan)的(de)(de)角(jiao)(jiao)度(du)(du)(du)便是(shi)该(gai)待测(ce)物(wu)资(zi)溶(rong)液的(de)(de)旋(xuan)光(guang)(guang)(guang)度(du)(du)(du)
