Ọ rụrụ ọrụ ọsụ ụzọ na nyocha spectral, ma nwalee foto mbara igwe. O mepụtara ngwá ọrụ maka ọmụmụ ihe ya, gụnyere micrometer maka ịtụ foto, igwe maka imepụta grating diffraction a na-achịkwa nke ọma, na teliskop mbụ e mere kpọmkwem maka astrophotography. Site n'iji ngwá ọrụ ya mee ihe, Rutherfurd mepụtara nchịkọta foto dị mma nke Sun, Ọnwa, na mbara ala, yana ụyọkọ kpakpando na kpakpando ruo ogo nke ise.
