光(guang)學基準樣(yang)(yang)(yang)板(原(yuan)器)簡稱為(wei)(wei)樣(yang)(yang)(yang)板,其中(zhong)包括(kuo)基準樣(yang)(yang)(yang)板、工(gong)(gong)作樣(yang)(yang)(yang)板、曲率樣(yang)(yang)(yang)板等,它是基于光(guang)波干(gan)涉現(xian)象來測(ce)量光(guang)學表面(mian)誤(wu)差的(de)一種(zhong)形(xing)狀樣(yang)(yang)(yang)板,且已經(jing)成為(wei)(wei)光(guang)學零件制造過程中(zhong)使用(yong)最廣(guang)泛,最簡便的(de)一種(zhong)精密測(ce)量工(gong)(gong)具,所以它的(de)面(mian)形(xing)精度比(bi)一般光(guang)學零件要高,為(wei)(wei)了保證質量,球面(mian)必須凹凸成對制造,加工(gong)(gong)過程中(zhong)還(huan)需反復用(yong)儀器測(ce)量以確保曲率半徑(jing)和面(mian)型精度。
