Mafotokozedwe Pamwamba

Ubwino Wapamwamba

Ubwino wa mawonekedwe owoneka umagwiritsidwa ntchito poyesa mawonekedwe amtundu wa chinthu chowoneka bwino ndipo umaphimba zolakwika zingapo monga zokopa ndi maenje.Zambiri mwazolakwika zapamtundazi ndizodzikongoletsera ndipo sizikhudza kwambiri magwiridwe antchito a dongosolo, ngakhale, zitha kuyambitsa kuviika kwapang'onopang'ono mumayendedwe adongosolo komanso kubalalitsa bwino kwa kuwala kobalalika.Komabe, malo ena adzakhala okhudzidwa kwambiri ndi zotsatirazi, monga: malo okhala ndi ndege zazithunzi, pomwe zolakwikazi zimatha kupanga kuyang'ana, ndi malo omwe ali ndi mphamvu zambiri, kumene zolakwikazi zimatha kuonjezera kuyamwa kwa mphamvu ndikuwononga mankhwala opangidwa ndi kuwala.Mafotokozedwe omwe amagwiritsidwa ntchito kwambiri pamtundu wapamtunda ndi kukanda ndi mapiting omwe amawonetsedwa ndi MIL-PRF-13830B.Mayina okanda amazindikiridwa pofanizira zingwe zapamtunda ndi mndandanda wazomwe zimaperekedwa pansi pamikhalidwe yowunikira.Chifukwa chake, m'malo mofotokoza zokopa zake zenizeni, dzina lokandali limawayerekeza ndi zokopa wamba kutengera zomwe MIL imafunikira.Mayina a maenje, komabe, amagwirizana mwachindunji ndi nsonga kapena maenje pamtunda.Mayina a dzenje amawerengedwa pogawa m'mimba mwake mwa ma microns ndi 10. Nthawi zambiri, tsatanetsatane wa dzenje pakati pa 80 ndi 50 amaonedwa kuti ndi abwino kwambiri, pakati pa 60 ndi 40 adzakhala olondola, ndipo pakati pa 20 ndi 10 amaonedwa kuti ndi olondola kwambiri. khalidwe.

Kusalala kwa pamwamba

p>Kupendekera kwapamwamba ndi mtundu wa zinthu zomwe zimayesa kulondola kwapamtunda, ndipo zimagwiritsidwa ntchito kuyeza kupatuka kwa malo athyathyathya monga magalasi, zidutswa zamawindo,prisms, kapena magalasi athyathyathya.Mutha kuyeza kupatukaku pogwiritsa ntchito kristalo wowoneka bwino, womwe ndi wokwera kwambiri, wolondola kwambiri womwe umagwiritsidwa ntchito poyerekeza kusalala kwa zitsanzo.Pamene ndege ya mankhwala opangidwa ndi kuwala imayikidwa motsutsana ndi optics, mikwingwirima imawoneka, mawonekedwe ake omwe amasonyeza kusalala kwa pamwamba pa mankhwala opangidwa ndi kuwala koyesedwa.Ngati mikwingwirimayo ili yotalikirana mofanana ndipo ili mizere yowongoka yofanana, ndiye kuti mawonekedwe owoneka bwino omwe amayesedwa amakhala athyathyathya ngati kristalo wowoneka bwino.Ngati mikwingwirimayo yapindika, kuchuluka kwa mikwingwirima pakati pa mizere iwiri yodukaduka (mzere umodzi wodukidwa wopendekeka mpaka pakatikati pa mzerewo ndi wina wokhotakhota wodutsa kumapeto kwa mzere womwewo) umaloza ku cholakwika chosalala.Kupatuka kosalala nthawi zambiri kumayesedwa potengera ma ripple values ​​(λ), omwe amapangidwa ndi mafunde angapo a malo oyesera.Mzere umodzi umafanana ndi ½ wa utali wotalika.Kusalala kwa 1λ kumawonetsa mulingo wabwino kwambiri;kusalala kwa λ/4 kukuwonetsa mulingo wolondola;ndi kusalala kwa λ/20 kumawonetsa mulingo wolondola kwambiri.

Nambala ya kabowo

Nambala ya kabowo ndi mtundu wa katchulidwe kamene kamayesa kulondola kwa pamwamba, komwe kumagwiritsidwa ntchito pa malo opindika kapena malo okhala ndi mphamvu.Kuyesa kwa nambala ya kabowo ndi kofanana ndi kuyesa kwa flatness chifukwa kumafananiza pamwamba ndi malo ofotokozera omwe ali ndi radius yolondola yopindika.Pogwiritsa ntchito mfundo yosokoneza yomwe imapangidwa ndi kusiyana pakati pa malo awiriwa, mawonekedwe osokoneza a mikwingwirima amagwiritsidwa ntchito kusonyeza kupatuka pakati pa mayesero ndi malo ofotokozera.Kupatuka kuchokera pazambiri kudzatulutsa mphete zingapo zotchedwa mphete za Newton.Pamene mphete zilipo, kupatuka kumakulirakulira.Chiwerengero cha mphete zakuda kapena zowala, m'malo mwa kuchuluka kwa mphete zakuda ndi zowala, ndizofanana kuwirikiza kawiri kulakwitsa kwa mafunde.

Kusakhazikika

Kusakhazikika ndi mtundu wazinthu zomwe zimayesa kulondola kwa pamwamba ndikufotokozera kupatuka kwa mawonekedwe apamwamba kuchokera ku mawonekedwe apamwamba.Kusakhazikika kumayesedwa mofanana ndi nambala ya kabowo.Kusakhazikika ndi njira yozungulira yozungulira yomwe imapangidwa poyerekeza malo oyesera ndi malo ofotokozera.Kumwamba kukakhala ndi kabowo ka mikwingwirima yopitilira 5, zimakhala zovuta kuzindikira mawonekedwe ang'onoang'ono ocheperako kuposa mizere umodzi.Choncho, ndizozoloŵera kutchula chiŵerengero cha chiwerengero cha mabowo ndi kusakhazikika kwa pamwamba kotero kuti ndi pafupifupi 5: 1.

Pamwamba Pamwamba/pamwamba roughness

Kumaliza pamwamba, komwe kumadziwikanso kuti kuuma kwapamtunda, kumagwiritsidwa ntchito kuyeza zolakwika zazing'ono pamtunda.Nthawi zambiri amakhala chifukwa cha kusapukutidwa bwino.Malo okhwima amakhala osamva ma abrasion kuposa osalala ndipo sangakhale oyenera kugwiritsa ntchito zina, makamaka omwe amagwiritsa ntchito ma lasers kapena malo otenthedwa kwambiri, chifukwa chotheka kusweka pang'ono kapena zolakwika pamalo a nucleation.Kulekerera kwa kupanga pakumaliza kwapamwamba ndi 50Å RMS pamtundu wapakati, 20Å RMS pamtundu wolondola, ndi 5Å RMS wamtundu wapamwamba.

Kuti mumve zambiri zatsatanetsatane, chonde onani zathucatalog opticskapena omasuka kulankhula nafe kuti mudziwe zambiri.
