Nws yog thawj tug pionered los ntawm Jansen txiv thiab tus tub ntawm lub Netherlands nyob rau hauv 1590.

Muaj ntau hom kev kho qhov muag me me, tshwj tsis yog hauv feem ntau, muaj lub tsom iav tsau tsau, ib lub tshuab xaj nrog qhov tsaus nti saib, yog li ntawd qhov nqaj nqaj hlau tsis yog txhaj ntawm hauv plawv nruab nrab, tab sis los ntawm qhov ua kom pom qhov tsom iav specimen. Fluorescence microscope yuav siv ultraviolet lub teeb raws li qhov chaw, ua rau cov khoom tsis muaj teeb meem los tawm ib lub tshuab tsom xam cov kab mob. Tus qauv yog: tsom iav, iav raj, sib tw, lub hom phiaj, kev sib tw, los ntawm lub qhov teeb, shading cuab yeej, ntsiav tshuaj clip, reflector, iav rooj, coarse-coke helix, nplua-coke helix, daim iav caj npab, daim iav kem.
