I tēnei wā o te kimi hapa iti-micron—ahakoa mō ngā anga haurua-ira, ngā pepa whakarewa pākahiko EV, ngā moroiti-whatu rānei—ko te mahi a te pūnaha tirotiro whatu ehara i te mea ko ngā kāmera me ngā rauropi anake e whakawhirinaki ana, engari ko te pumau ā-tinana o tōna ara whatu. Kei te ngako o tēnei pumau ko ngā wāhanga karāhe tino tika: ngā karāhe arotahi, ngā matapihi, ngā porotiti, me ngā papa tohutoro i hangaia ki ngā ātete taumata-nanomita, ā, i hangaia mai i ngā rauemi motuhake mō te iti o te toronga.
I ZHHIMG, e mahi ana mātou ki ngā OEM tirohanga mīhini matua me ngā whakauru tirotiro whatu aunoa (AOI) me ngā wāhanga karāhe ritenga e whakarite ana i te kore wera, te pono o te mata o te ngaru, me te āheinga ki te whakahoki anō mō te wā roa—ahakoa i roto i ngā taiao wheketere kaha te whakaputa.
Te Wero Huna: Te Rerenga Wera i ngā Ara Whatu
Ko te tauwehenga whānui wera (CTE) o ngā mōhiti whatu paerewa (hei tauira, BK7) kei te 7–8 ppm/°C. I roto i tētahi raina whakaputa 24/7 e piki haere ana te pāmahana taiao mā te ±3°C, ka taea e tēnei te whakaputa i ngā nekehanga arotahi, i te he rānei o te tūnga neke atu i te 5 µm—he nui hei whakapōuri i ngā āhuatanga pai, hei whakaputa rānei i ngā whakakorenga teka.
Ko ngā pūnaha tirotiro kounga teitei e hiahia ana ki ngā karāhe iti te whānui pēnei i:
- ULE® (Karāhe Whakawhanui Tino Iti) – CTE ≈ ±0.03 ppb/°C tata ki te pāmahana rūma
- Zerodur® (Schott) – CTE < 0.1 ppb/°C i runga ake i te 0–50°C
- Karāhe-uku kua pania ki te Clearceram-HS / TiO₂ – tata ki te kore te CTE me te kaha ki te whakakanapa
Ka mau tonu te pono o te tuaka whatu puta noa i ngā huringa wera i roto i ēnei rauemi, kia ōrite ai te taumira me te kore e whakatikatika anō.
Te Huri Karāhe Tika: Te Wāhi e Hiranga ai te Mahi a ngā Maikoroni
Kāore e ranea te whiriwhiri i te rauemi tika—me tino tika te āhuahanga. Ko ngā āheinga o ZHHIMG kei roto i te whare:
- Te whakakanapa i raro i te whakatuwheratanga me te whakaotinga magnetorheological (MRF) mō te tika o te mata λ/20
- Te whakarara ≤1 arcsec i runga i ngā takirua matapihi mō ngā huihuinga arotahi telecentric
- Te taratara o te mata <0.5 nm RMS hei whakaiti i te marara i roto i te whakaahua o te mara kanapa/mara pōuri
- Ngā paninga AR ritenga kua arotauhia mō ngā roangaru 405 nm, 532 nm, SWIR rānei
"Nā te whakawhiti i tā mātou matapihi tohutoro mai i BK7 ki Zerodur i whakaiti i te rerekētanga ine taumata-ki-te-taumata mā te 62% i roto i tā mātou pūnaha PCB AOI."

Kei tua atu i te Karāhe: Ngā Otinga Rauemi-maha kua Whakauruhia
Ko te mea e wehewehe ana i a ZHHIMG ko tō mātou kaha ki te whakakotahi i te karāhe tino tika me ngā hanganga whakarewa me te uku i roto i te huihuinga kotahi:
- Te here i te karāhe whānui-iti ki ngā maunga Invar mō te whakairinga kinematic kore-ahotea
- Te whakauru i ngā porotiti karāhe ki roto i ngā whare konumohe me ngā atanga CTE e ōrite ana
- Te whakawhanake tahi i ngā kōwae whatu-mīhini ranu me ngā taputapu whakawhirinaki kua whakauruhia
Mā tēnei tohungatanga whakawhiti-rauemi ka taea te whakauru pai ki roto i tō miihini whatu o nāianei—me te kore e whakararu i te whakaritenga, i te whanonga wera rānei.
Ngā Taupānga e Tautokona ana e Mātou
- Te tirotiro i te anga whakarewa me te reticle
- Te kimi hapa o te whakaaturanga papatahi (FPD)
- Matawai irahiko pākahiko lithium-ion
- Te ine tika mō ngā arotahi aspheric
- Ngā pūwhakaata rama hanganga 3D teitei-taumira
Kua rite koe ki te whakakore i te rere wera i roto i tō pūnaha tirotiro?
Ka tukuna e ZHHIMG te tautoko katoa—mai i te kōwhiringa rauemi me te tātari ātete whatu ki te tuku whaimana me ngā pūrongo whakamātautau interferometric.
Kaupapa mō ngā Kaihanga Pūnaha Tirohanga o te Hauwhā Tuarua o te tau 2026:
→ Tauira kore utu o te karāhe iti-whanui (Zerodur, rite rānei)
→ Arotake i te āheinga o te manawanui i roto i ngā haora 48
→ Te wā arataki poto noa iho i te 12 ngā rā mō ngā wāhanga plano paerewa
→ Tauira kore utu o te karāhe iti-whanui (Zerodur, rite rānei)
