Usoro laser na tebụl anya.

Tebụl anya bụ ikpo okwu nchịkwa ịma jijiji nke a na-eji akwado usoro eji eme ihe maka nnwale metụtara laser na anya na sayensị, injinia na n'ichepụta. ^[1] na-emepụta elu nke tebụl ndị a ka ha sie ike nke ukwuu na obere ntụgharị ka nhazi nke ihe ndị a na-ahụ anya wee nọgide na-akwụsi ike ka oge na-aga. Ọtụtụ usoro anya chọrọ ka a na-eme ka ịma jijiji nke ihe anya dị obere. N'ihi ya, tebụl anya na-adịkarị arọ ma na-etinye ihe ndị na-eme ka ọ ghara ịma jijiji na ihe ndị na'ime ha. Ọtụtụ ^[2]-eji ihe na-ekpuchi ikuku nke na-arụ ọrụ dị ka ihe nzacha dị ala, na-ebelata ikike nke ịma jijiji n'ala iji kpatara ịma jijiji na tebụl.

N'elu tebụl anya na-abụkarị igwe anaghị agba nchara nwere oghere akụkụ akụkụ anọ nke oghere apịara ọnụ na mpaghara metric ma ọ bụ nke alaeze ukwu:

• metric: M6 na grid 25 mm 
• alaeze ukwu: 1⁄4"-20 UNC na 1" (25.4 mm) grid 

Obere oghere anya, bench, na rails bụ ihe owuwu dị mfe nke na-arụ ọrụ yiri nke tebụl anya. A na-eji ihe ndị a eme ihe na nkuzi na nyocha na mmepe, a na-ejikwa ha eme ihe mgbe ụfọdụ iji kwado usoro anya na-adịgide adịgide na ngwaọrụ ndị a rụchara dịka lasers.

Na usoro anya, ọkachasị ndị metụtara interferometry, nhazi nke akụkụ ọ bụla ga-abụrịrị nke ziri ezi - ziri ezi ruo n'otu akụkụ nke Ogologo oge - na-abụkarị narị nanometers ole na ole. Ọbụna obere ịma jijiji ma ọ bụ nrụgide na tebụl ebe a na-etinye ihe ndị ahụ nwere ike iduga na ọdịda zuru oke nke nnwale. N'ihi ya, mmadụ chọrọ tebụl siri ike nke na-adịghị agagharị ma ọ bụ na-agbanwe agbanwe, ọbụlagodi n'okpuru ibu ma ọ bụ ịma jijiji. N'elu tebụl ga-adịkwa nnọọ larịị, na-ekwe ka nkenke ngwa anya mounts na-eme ka ezi kọntaktị na tebụl na-enweghị mkpatụ na ikwado mfe mgbakọ nke ngwa anya usoro.

A na-emekarị tebụl anya nke oge a nke nchara, aluminom, ma ọ bụ eriri carbon, nke nwere nnukwu ihe owuwu lattice ebuanu na-ekewa. N'elu na-enwekarị oghere nke eriri eri nke na-enye ohere ka a kụchie ihe ndị ahụ ka ọ dabara na nhazi usoro anya. Enwere ike idobe akụrụngwa n'elu igwe site na ntọala magnetik. Ọtụtụ mgbe, ụkwụ tebụl na-abụ ihe na-akụda ụda pneumatic. Maka nhazi nke ọma karị, mmadụ na-egbochikwa mmegharị ikuku na gradients okpomọkụ site n'ịchichi elu n'ime igbe plastik na-enweghị atụ dịka Plexiglas. Otu nwekwara ike iji "flowbox" ngwaọrụ nke na-emepụta ikuku laminar nke na-erute ala, na-echekwa ya na okpomọkụ mgbe niile site na ntụ oyi pụrụ iche.
