Sei Granite Surface Plates Inofambisa sei Optical Component Testing?

 

Matanho eGranite maturusi akakosha mumunda weinjiniya chaiyo, kunyanya mukuyedzwa uye kuenzanisa zvinhu zvemaziso. Yakagadzirwa kubva kune yechisikigo granite, aya matanho anopa yakagadzikana uye yakati sandara nzvimbo, iyo yakakosha kuti uwane zviyero zvakaringana mu optical test application.

Imwe yemabhenefiti makuru emapuratifomu egranite ndeye yakasarudzika flatness. Nzvimbo dzemapuratifomu aya dzakanyatsogadzirwa kuti dzive dzakati sandarara, kazhinji mukati memamicrons mashoma. Iyi nhanho yehutsanana yakakosha kana uchiyedza zvinhu zvemaziso zvakaita semalenzi nemagirazi, sezvo kunyangwe kutsauka kudiki kunogona kukonzera kukanganisa kukuru mukuita. Nekupa yakavimbika referensi ndege, mapuratifomu egranite anovimbisa kuti zvinhu zvemaziso zvinogona kurongeka uye kuyerwa.

Granite inozivikanwa zvakare nekusimba kwayo uye kuramba kupfeka. Kusiyana nezvimwe zvinhu zvinogona kukanganisa kana kupfeka nekufamba kwenguva, granite inochengetedza kutendeseka kwayo, ichiva nechokwadi chekuti bvunzo dzepamusoro dzinoramba dzichienderana kwenguva yakareba. Uku kugadzikana kunonyanya kukosha mukuongorora kwemaziso, uko kuyerwa kwakadzokororwa kunofanirwa kuburitsa mhedzisiro yakavimbika. Granite's inherent properties inoitawo kuti isanyanya kukurumidza kuwedzera kupisa, izvo zvinogona kukanganisa kuyerwa kwechiyero. Ichi chimiro chakakosha munzvimbo dzinowanzo chinja tembiricha.

Pamusoro pezvo, mapuratifomu egranite anowanzo shandiswa neakasiyana emhando yekuongorora michina, senge interferometers uye autocollimators. Midziyo iyi inoda chikuva chakagadzikana kuti chishande nemazvo, uye mapuratifomu egranite anopa rubatsiro rwakakodzera. Iko kusanganiswa kwegranite's flat surface uye rigidity inobvumira kurongeka kwakaringana uye kumira kwezvinhu zvemaziso, kufambisa kuyedzwa kwakaringana uye kuongororwa.

Mukupedzisa, mapuratifomu egranite anoita basa rakakosha mukuyedzwa kwechikamu chemaziso. Kupfava kwavo kusingaenzaniswi, kusimba, uye kugadzikana zvinovaita chinhu chakakosha pakuona chokwadi uye kuvimbika kwezviyero zvemaziso, zvichizobatsira mukusimudzira tekinoroji yemaziso.
