Kodhi huru yekugadzira zvishandiso zve optical: Midziyo ye granite inochera sei mapuratifomu ekukuya lenzi ane magadzirirwo akakwirira.

Mubasa rekugadzira zvishandiso zve optical, kunyatsojeka kwema lens kunosarudza zvakananga kunaka kwemifananidzo. Kubva kuma telescope emuchadenga kusvika kumidziyo midiki, kubva kumakamera epamusoro-soro kusvika kumichina ye photolithography chaiyo, kushanda kwakanaka kwechinhu chega chega che optical kunoenderana nerutsigiro rwema lens akanyatsojeka. Midziyo ye granite chaiyo, ine hunhu hwayo husina muganho, iri kuva kiyi yekugadzira mapuratifomu ekukuya ma lens akanyatsojeka, ichitungamira kugadzirwa kwemidziyo ye optical kusvika padanho idzva rekururama.
Zvakanakira zvechisikigo zvemidziyo yegranite chaiyo
Granite yakagadzirwa kuburikidza nemaitiro e geological kwemazana emamiriyoni emakore uye ine hunhu hwakasiyana hwepanyama, zvichiita kuti ive chinhu chakanakira kuvaka mapuratifomu ekukuya lenzi akanyatsogadzirwa. Chekutanga, chiyero chekuwedzera kwekushisa kwegranite chakaderera zvakanyanya, kazhinji chinotangira pa5 kusvika pa7×10⁻⁶/℃, uye hachina kukanganiswa nekuchinja-chinja kwekushisa kwezvakatipoteredza. Munguva yekukuya lenzi, kupisa kunokonzerwa nekushanda kwemidziyo kana shanduko mukupisa kwezvakatipoteredza hazvizokonzere kuchinjika kwakakosha kwepuratifomu yekukuya yegranite, nokudaro zvichiita kuti kururama kwemalenzi kurambe kwakasimba mukati menguva yese yekukuya uye kudzivirira kutsauka kwemalenzi kunokonzerwa nekuwedzera kwekupisa uye kudzikira.

Chechipiri, granite ine simba rakanaka kwazvo rekudzivirira kusviba. Kukuya lenzi yemaziso kunoda nzvimbo yakagadzikana yekugadzirisa. Kunyangwe kudedera kudiki kunogona kukonzera zvikanganiso pamusoro pe lenzi. Granite inogona kunyudza simba rekunze re vibration, kuderedza kupindirana kwe vibration panguva yekukuya, kuderedza simba re vibration ne60% kusvika 80%, kuve nechokwadi chekuti nzvimbo chaiyo iri pakati pechishandiso chekukuya ne lenzi, uye kubatsira kuita kuti pamusoro pe lenzi pave nekutsvedzerera kwakanyanya.

Pamusoro pezvo, granite ine kuomarara kwakanyanya uye inodzivirira kupfeka zvakanyanya, ine kuomarara kweMohs kwe6 kusvika ku7. Mukushanda kwenguva refu uye kwe-frequency high-frequency lens, mapuratifomu ekukuya granite haawanzo pwanyika, anogona kugara achishanda zvakanaka, kuwedzera hupenyu hwekushanda kwemidziyo, uye kuderedza mari yekugadzirisa.
Tekinoroji yekugadzirisa nemazvo yemapuratifomu ekukuya egranite
Kuti ishandise zvizere mabhenefiti ekushanda kwegranite, puratifomu yekukuya lenzi ine magadzirirwo akanyatsonaka inoshandisa maitiro epamusoro etekinoroji panguva yekugadzira. Kuburikidza nehunyanzvi hwekukuya nekupukuta zvine hungwaru, kutsetseka kwepuratifomu yegranite kunogona kudzorwa mukati me ±0.002mm/m, uye kukweshana kwepamusoro kunogona kusvika padanho re nanometer. Hunhu uhwu hwepamusoro-soro hunopa nzvimbo chaiyo yekuyera yekukuya lenzi, zvichiita kuti zvishandiso zvekukuya zvigone kugadzirisa lenzi zvakaenzana uye zvakadzikama.

Zvichakadaro, mukugadzirwa nekugadzirwa kwepuratifomu yekukuya yegranite, maumbirwo chaiwo emakanika uye masisitimu ekufamba zvinosanganiswa. Semuenzaniso, nekubatanidza rails dzinotungamira mhepo dzakanyatsojeka uye masisitimu ekutyaira eservo motor, maturusi ekukuya anogona kuita kufamba kwakatsetseka uye kwakanyatsojeka pachikuva, nekunyatso tarisa kufamba kwe±0.005mm. Kudzora kufamba uku kwakanyatsojeka, pamwe nekugadzikana kwepuratifomu yegranite, kunogona kusangana nezvinodiwa zvekukuya kwenzvimbo dzakakombama dzakakombama dzemarudzi akasiyana emalenzi. Ingave malenzi akakombama, malenzi akakombama, kana malenzi aspheric, kugadziriswa kwakanyatsojeka kunogona kuitwa.
