分(fen)光(guang)光(guang)度(du)計的(de)基本原理(li)是利用光(guang)的(de)吸收和反(fan)射現象，對物質(zhi)進行定(ding)量分(fen)析(xi)。當光(guang)通過物質(zhi)時，物質(zhi)會吸收特定(ding)波長(chang)的(de)光(guang)線，導致(zhi)光(guang)譜(pu)(pu)強度(du)和波長(chang)的(de)變(bian)化。分(fen)光(guang)光(guang)度(du)計通過測量這(zhe)種(zhong)變(bian)化，確定(ding)物質(zhi)的(de)濃度(du)和性質(zhi)。中(zhong)國臺灣光(guang)譜(pu)(pu)儀分(fen)光(guang)光(guang)度(du)計推薦(jian)分(fen)光(guang)光(guang)度(du)計的(de)光(guang)譜(pu)(pu)也是需要考慮(lv)的(de)一個重要因素(su)。
