Prism ndi chinthu chowoneka bwino chomwe chimachotsa kuwala pamakona enaake kutengera zomwe zidachitika ndikutuluka. Ma prism amagwiritsidwa ntchito kwambiri pamakina owoneka bwino kuti asinthe njira zowunikira, kupanga zosintha zazithunzi kapena kupotoza, ndikuwongolera ntchito zowunikira.
Ma prism omwe amagwiritsidwa ntchito posintha komwe amayendera nyali zowala amatha kugawidwa kukhala ma prism ndi refracting prism.
Ma prism owonetsera amapangidwa pogaya malo amodzi kapena angapo onyezimira pa galasi pogwiritsa ntchito mfundo yowunikira mkati ndiukadaulo wokutira. Kuwunikira kwathunthu kwamkati kumachitika pamene kuwala kochokera mkati mwa prism kukafika pamwamba pa ngodya yayikulu kuposa yofunikira pakuwunikira kwathunthu kwamkati, ndipo kuwala konse kumawonekera mkati. Ngati chiwonetsero chamkati chonse cha kuwala kwa chochitikacho sichingachitike, zokutira zonyezimira zachitsulo, monga siliva, aluminiyamu, kapena golide, ziyenera kuyikidwa pamwamba kuti zichepetse kutayika kwa mphamvu ya kuwala pamalo owala. Kuphatikiza apo, kuti muwonjezere kufalikira kwa prism ndikuchepetsa kapena kuchotsa kuwala kosokera m'dongosolo, zokutira zotsutsana ndi mawonedwe apadera zimayikidwa pamalo olowera ndi otuluka a prism.
Pali mitundu yambiri ya ma prisms owoneka mosiyanasiyana. Nthawi zambiri, imatha kugawidwa kukhala ma prism osavuta (monga prism yakumanja, pentagonal prism, prism ya Nkhunda), prism padenga, piramidi prism, prism pawiri, ndi zina zambiri.
Refracting prisms zimachokera pa mfundo ya refraction kuwala. Amakhala ndi malo awiri owonetsera, ndipo mzere wopangidwa ndi mphambano ya malo awiriwa amatchedwa refractive edge. Ngodya yapakati pazigawo ziwiri zobwereza imatchedwa refraction angle ya prism, yoimiridwa ndi α. Ngodya yapakati pa cheza chotuluka ndi chezacho imatchedwa deviation angle, yoimiridwa ndi δ. Pa prism yopatsidwa, ngodya yowunikidwa α ndi refractive index n ndizokhazikika, ndipo mbali yokhotakhota δ ya prism ya refractive imangosintha ndi zochitika I za cheza. Pamene njira ya kuwala ya kuwala ndi symmetrical ndi refracting prism, mtengo wochepa wa ngodya yokhotakhota umapezeka, ndipo mawuwa ndi awa:
Mphepete mwa wedge kapena wedge prism imatchedwa prism yokhala ndi ngodya yaying'ono kwambiri. Chifukwa cha ngodya yopendekeka yosasamala, pamene kuwala kukuchitika molunjika kapena molunjika, mawu oti atembenuke pa ngodya akhoza kukhala wosavuta monga: δ = (n-1) α.
Makhalidwe okutikira:
Nthawi zambiri, makanema owunikira a aluminiyamu ndi siliva amayikidwa pagalasi la prism kuti awonetsere kuwala. Makanema otsutsa-reflection adakutidwanso pazomwe zidachitika ndikutuluka kuti awonjezere kufalikira ndikuchepetsa kuwala kosokera m'magulu osiyanasiyana a UV, VIS, NIR, ndi SWIR.
Minda yofunsira: Ma Prism amapeza ntchito zambiri pazida zamagetsi, kafukufuku wasayansi, zida zamankhwala, ndi madera ena. - Zida zama digito: makamera, ma TV otsekeka (ma CCTV), ma projekita, makamera a digito, makamera a digito, magalasi a CCD, ndi zida zosiyanasiyana zowonera. - Kafukufuku wa sayansi: ma telescopes, ma microscopes, milingo / zowunikira zowunikira zala zala kapena zowonera mfuti; otembenuza dzuwa; zida zoyezera zamitundu yosiyanasiyana. - Zida zamankhwala: ma cystoscopes/gastroscopes komanso zida zosiyanasiyana zochizira laser.
Jiujon Optics imapereka zinthu zingapo zamaprism monga ma prism akumanja opangidwa kuchokera ku galasi la H-K9L kapena quartz yosakanikirana ndi UV. Timapereka ma prisms a pentagon, ma prisms a Nkhunda, ma prisms a Padenga, ma prisms a pakona-cube, ma silika a pakona-cube prisms a UV, ndi ma prisms oyenerera ku ultraviolet (UV), kuwala kowoneka (VIS), mabandi apafupi ndi infrared (NIR) mosiyanasiyana mosiyanasiyana. milingo.
Zogulitsazi zimakutidwa ngati filimu yowonetsera aluminium / siliva / golide / anti-reflection film/nickel-chromium protection/penti yakuda.
Jiujon imapereka ma prism makonda ogwirizana ndi zomwe mukufuna. Izi zikuphatikizanso zosintha kukula/magawo/zokonda zokutira ndi zina. Khalani omasuka kutilankhula nafe kuti mumve zambiri.
