Spectrometers bụ ngwaọrụ dị mkpa na nyocha sayensị ọgbara ọhụrụ yana ngwa ụlọ ọrụ mmepụta ihe. Iji gbasaa ngwa ha n'ihu, ndị nchọpụta atụpụtala spectrometer nke ọwa abụọ nke na-etinye subgrating asatọ, na-edochi akụkụ ndị na-akpụ akpụ a na-eji eme ihe n'ụdị ọdịnala. A na-eji ihe nlegharị anya quadrifold abụọ maka ntụgharị na onyonyo n'ime elu na ala focal nke igwefoto DHyana 90A, n'otu n'otu. Ịrụ ọrụ nke igwefoto na 400nm bụ ihe dịka 90%. Na mgbakwunye na uru bara uru nke sistemu spectroscopic, kọmpat imewe nke spectrometer na-enyere aka n'otu oge nha nke otutu ụdịdị.
