Tawhā: Te tuku >92% puta noa i te awhe roangaru kua tohua (te tikanga 400-2500 nm) me te taratara o te mata Ra ≤ 0.5 nm.
He aha te Hiranga mō ngā Pūnaha Whakahāngai:

Ngā Whakaritenga Ahupūngao o te Papatahi:
Mō te ine whakawhiti taiaho me te taiaho HeNe 632.8 nm, ko te papatahi o te mata o te λ/4 (158 nm) ka puta he hapa ngaru o te haurua ngaru (e rua te rerekētanga o te mata) i te taunga noa. Ka taea e tēnei te whakaputa hapa ine neke atu i te 100 nm—kāore e whakaaetia mō ngā tono ine tika.
Whakarōpūtanga mā te Taupānga:
| Whakatakotoranga Papatahi | Akomanga Tono | Ngā Whakamahinga Noa |
|---|---|---|
| ≥1λ | Taumata arumoni | Te whakamārama whānui, te whakaritenga kore-tino |
| λ/4 | Taumata mahi | Ngā taiaho mana iti-waenga, ngā pūnaha whakaahua |
| ≤λ/10 | Te kounga tika | Ngā taiaho mana-teitei, ngā pūnaha ine |
| ≤λ/20 | Tino tika | Te whakawhitiwhiti ira, te tuhi whakaahua, te huihuinga whakaahua |
Ngā Werohanga Hanga:
He nui ngā wero hanga ina tutuki te papatahi o te λ/20 puta noa i ngā papa nui (200 mm+). Ko te whanaungatanga i waenga i te rahi o te papa me te papatahi ka taea te whakatutuki e whai ana i tētahi ture tapawhā: mō te kounga tukatuka ōrite, ka taurite te hapa papatahi ki te tapawhā o te diameter. Mā te whakarea i te rahi o te papa mai i te 100 mm ki te 200 mm ka taea te whakanui ake i te rerekētanga papatahi mā te tauwehenga o te 4.

I te tīmatanga, i whakamahia e te kaihanga taputapu tuhi whakaahua ngā papa karāhe borosilicate me te papatahi o te λ/4 mō ngā wāhanga whakahāngai kopare. I te nekehanga ki te tuhi whakaahua rumaki 193 nm me ngā whakaritenga whakahāngai i raro i te 30 nm, i whakahoutia e rātou ki ngā papa silica hanumi me te papatahi o te λ/20. Ko te hua: i pai ake te tika o te whakahāngai mai i te ±80 nm ki te ±25 nm, ā, i heke iho ngā reiti hapa mā te 67%.
Te Pūmautanga i roto i te Wā:
Ehara i te mea me whakatutuki noa i te papatahi o te mata i te tīmatanga engari me pupuri tonu mō te roanga o te oranga o te wāhanga. He tino pai te pumau o ngā papa karāhe mō te wā roa, me te rerekētanga o te papatahi i raro i te λ/100 ia tau i raro i ngā āhuatanga taiwhanga noa. He rerekē, ka taea e ngā papa whakarewa te whakaatu i te whakangāwari o te ahotea me te ngokingoki, ka heke te papatahi i roto i ngā marama.

Te Wero Whakawhanuitanga Wera:
Mō te papa whakarārangi 200 mm:

| 0.05 (ULE®) | 0.01 µm | 0.05 µm |
| 0.007 (Zerodur®) | 0.0014 µm | 0.007 µm |
Ngā Akomanga Rauemi mā te CTE:
Karāhe Whānui Tino Iti (ULE®, Zerodur®):

Karāhe Whatu Paerewa (N-BK7, Borovloat®33):
- CTE: 7.1-8.2 × 10⁻⁶/K
- Ngā Whakamahinga: Te whakahāngaitanga whatu whānui, ngā whakaritenga tika taurite
- Painga: He pai te tuku whatu, he iti ake te utu
- Herenga: Me whakahaere te pāmahana hohe mō ngā tono tino tika
Ātete Ru Wera:
I tua atu i te rahi o te CTE, he mea nui te ātete ki te ru wera mō te huringa pāmahana tere. Ko ngā karāhe silica me te borosilicate kua hanumi (tae atu ki te Borofloat®33) he ātete ru wera tino pai, e tu atu ana i ngā rerekētanga pāmahana neke atu i te 100°C me te kore e whati. He mea nui tēnei āhuatanga mō ngā pūnaha whakahāngai e pāngia ana e ngā huringa taiao tere, e te whakamahana ā-rohe rānei mai i ngā taiaho mana-teitei.
Taupānga o te Ao Tūturu:
Ka mahi te pūnaha whakaritenga photonics mō te hononga muka whatu i roto i te taiao hangahanga 24/7 me ngā rerekētanga pāmahana tae atu ki te ±5°C. Mā te whakamahi i ngā papa konumohe (CTE = 23 × 10⁻⁶/K) ka hua ake he rerekētanga pai o te hononga o te ±15% nā ngā huringa āhua. Mā te huri ki ngā papa taiao AF 32® (CTE = 3.2 × 10⁻⁶/K) ka whakaitihia te rerekētanga pai o te hononga ki raro iho i te ±2%, ā, ka tino whakapai ake i te hua hua.
Ngā Whakaaro mō te Rōnakitanga Pāmahana:
Ahakoa he iti ngā rauemi CTE, ka taea e ngā pikinga pāmahana puta noa i te papa te whakararu i te rohe. Mō te ātete papatahi λ/20 puta noa i te papa 200 mm, me pupuri tonu ngā pikinga pāmahana i raro i te 0.05°C/mm mō ngā rauemi me te CTE ≈ 3 × 10⁻⁶/K. Me whiriwhiri rauemi me te hoahoa whakahaere wera tika tēnei.
Whakatakotoranga 4: Ngā Āhuatanga Mīhini me te Whakaiti i te Wiri
Tawhā: Te modulus a Young 67-91 GPa, te waku ā-roto Q⁻¹ > 10⁻⁴, me te kore o te birefringence o te ahotea ā-roto.
He aha te Hiranga mō ngā Pūnaha Whakahāngai:
Ko te pumau ā-mīhini e kapi ana i te pakari o ngā āhuatanga i raro i te kawenga, ngā āhuatanga whakaiti wiri, me te ātete ki te birefringence i puta mai i te ahotea—he mea nui katoa ēnei hei pupuri i te tika o te whakarārangi i roto i ngā taiao hihiri.
Te Tauwehenga Pūmau me te Pakari:
Ko te nui ake o te modulus elastic ka nui ake te ātete ki te piko i raro i te kawenga. Mō te kurupae tautokona ngāwari o te roa L, te matotoru t, me te modulus elastic E, ko te piko i raro i te kawenga he L³/(Et³). Ko tēnei whanaungatanga pūtoru whakamuri ki te matotoru me te whanaungatanga tika ki te roa e whakaatu ana i te hiranga o te pakari mō ngā papa nui.
| Rauemi | Te Tauwehenga o Young (GPa) | Pakaritanga Motuhake (E/ρ, 10⁶ m) |
|---|---|---|
| Hiraka Whakakotahi | 72 | 32.6 |
| N-BK7 | 82 | 34.0 |
| AF 32® taiao | 74.8 | 30.8 |
| Konumohe 6061 | 69 | 25.5 |
| Rino (440C) | 200 | 25.1 |
Mātakitaki: Ahakoa te maitai te mea tino pakari, he rite tonu tōna pakari motuhake (ōwehenga pakari-ki-taumaha) ki te konumohe. He rite tonu te pakari o ngā rauemi karāhe ki ngā konganuku, engari he pai anō hoki ēnei: ngā āhuatanga kore-aukume me te kore o ngā ngaronga o te ia hurihuri.
Te waku ā-roto me te whakaiti:
Ko te waku ā-roto (Q⁻¹) te mea e whakatau ana i te kaha o te rauemi ki te whakamarara i te pūngao wiri. Ko te tikanga ka whakaatuhia e te karāhe te Q⁻¹ ≈ 10⁻⁴ ki te 10⁻⁵, e whakarato ana i te whakamāmā auau-teitei pai ake i ngā rauemi tioata pēnei i te konumohe (Q⁻¹ ≈ 10⁻³) engari he iti iho i ngā pūmua. Ka āwhina tēnei āhuatanga whakamāmā waenga ki te pehi i ngā wiri auau-teitei me te kore e whakararu i te pakari auau-iti.
Rautaki Wehewehe Wiri:
Mō ngā papaaho whakahāngai whatu, me mahi tahi te rauemi papaaho me ngā pūnaha wehe:
- Wehenga Auau-Iti: E whakaratohia ana e ngā wehewehe hau me ngā auau haruru 1-3 Hz
- Te Whakaiti Auau-Waenga: Ka pehia e te waku ā-roto o te papa me te hoahoa hanganga
- Tātari Auau-Teitei: I tutuki mā te utaina papatipu me te kore taurite o te aukati
Te rua-whāititanga o te ahotea:
He rauemi kore-āhua te karāhe, nō reira kāore e tika kia whakaatuhia he birefringence ā-roto. Heoi, ka taea e te ahotea i puta mai i te tukatuka te whakaputa birefringence rangitahi ka pā ki ngā pūnaha whakahāngai mārama kua whakapōraruhia. Mō ngā tono whakahāngai tika e uru ana ki ngā hihi kua whakapōraruhia, me pupuri te ahotea toenga i raro i te 5 nm/cm (i inehia i te 632.8 nm).
Te Tukatuka Whakaora i te Ahotea:
Mā te whakamahana tika ka whakakorea ngā ahotea o roto:
- Te pāmahana whakamahana noa: 0.8 × Tg (te pāmahana whakawhiti karāhe)
- Te roanga o te whakamahana: 4-8 hāora mō te matotoru 25 mm (ngā unahi me te matotoru tapawhā)
- Te tere whakamatao: 1-5°C/haora mā te pūwāhi taumahatanga
Take o te Ao Tūturu:
I pāngia tētahi pūnaha whakarārangi tirotiro haurua-ā-ira e te hē o te whakarārangi me te kaha o te 0.5 μm i te 150 Hz. I kitea i roto i te rangahau he wiri ngā pupuri papa konumohe nā te mahi a te taputapu. Mā te whakakapi i te konumohe ki te karāhe borofloat®33 (he rite te CTE ki te silicon engari he pakari ake) i whakaiti i te kaha o te wiri mā te 70%, ā, i whakakorea hoki ngā hapa whakarārangi ā-wā.
Te Kaha Utaina me te Hurihuri:
Mō ngā papa whakahāngai e tautoko ana i ngā whatu taumaha, me tatau te piko i raro i te kawenga. Ko te papa silica kua hanumi he 300 mm te whānui, he 25 mm te matotoru, ka piko i raro i te 0.2 μm i raro i te kawenga 10 kg e pā ana ki waenganui—kāore e tika mō te nuinga o ngā tono whakahāngai whatu e hiahia ana kia tika te tūnga i roto i te awhe 10-100 nm.
Whakatakotoranga 5: Te Pūmautanga Matū me te Ātete ki te Taiao
Tawhā: Ātete waikura Akomanga 1 (e ai ki te ISO 719), ātete waikawa Akomanga A3, me te ātete huarere neke atu i te 10 tau me te kore e pirau.
He aha te Hiranga mō ngā Pūnaha Whakahāngai:
Mā te pumau matū ka pumau te āhua me te mahi whatu mō te wā roa i roto i ngā taiao rerekē—mai i ngā rūma ma me ngā kaihoko horoi kaha ki ngā tautuhinga ahumahi e pāngia ana e ngā whakarewa, te haumākū, me te huringa pāmahana.
Whakarōpūtanga Ātete Matū:
Ka whakarōpūtia ngā rauemi karāhe e ai ki tō rātou ātete ki ngā taiao matū rerekē:
| Momo Ātete | Tikanga Whakamātautau | Whakarōpūtanga | Paepae |
|---|---|---|---|
| Waiwaiora | ISO 719 | Akomanga 1 | <10 μg Na₂O rite mo ia karamu |
| Waikawa | ISO 1776 | Akomanga A1-A4 | Te ngaronga taumaha o te mata i muri i te pānga o te waikawa |
| Kawakawa | ISO 695 | Akomanga 1-2 | Te ngaronga taumaha o te mata i muri i te pānga ki te kawakore |
| Te huarere | Te whakaaturanga o waho | Tino pai | Kāore he hekenga e taea te ine i muri i ngā tau 10 |
Hototahi Horoi:
Me horoi auau ngā pūnaha whakahāngai whatu kia mau tonu ai te mahi. Ko ngā mea horoi noa ko:
- Waipiro Isopropyl (IPA)
- Āketona
- Wai whakakore i te ion
- Ngā otinga horoi whatu motuhake
He tino ātete ngā karāhe silica me te borosilicate kua hanumi ki ngā kaihoroi noa katoa. Heoi, ka taea e ētahi karāhe whatu (ina koa ko ngā karāhe kiripaka he nui te mata) te pāngia e ētahi whakarewa, ka whakawhāiti i ngā kōwhiringa horoi.
Te haumākū me te mimiti wai:
Ka pā te mimiti wai ki ngā mata karaihe ki te mahi whatu me te pumau o ngā āhua. I te 50% o te haumākū whanaunga, ka mimiti te silica hanumi i raro i te kotahi paparanga o ngā ngota wai, ka iti noa te huringa āhua me te ngaronga o te tuku whatu. Heoi, mā te poke o te mata me te haumākū ka puta he ira wai, ka heke te kounga o te mata.
Te Hototahi ki te Whakaputa Hau me te Korehau:
Mō ngā pūnaha whakahāngai e mahi ana i roto i te korehau (pērā i ngā pūnaha whatu ā-wāhi, i te whakamātautau rūma korehau rānei), he mea nui te tango hau. He tino iti ngā tere tango hau o te karāhe:
- Te silica kua hanumi: < 10⁻¹⁰ Torr·L/s·cm²
- Porosilicate: < 10⁻⁹ Torr·L/s·cm²
- Konumohe: 10⁻⁸ – 10⁻⁷ Torr·L/s·cm²
Nā tēnei ka waiho ko ngā papa karāhe te whiringa pai mō ngā pūnaha whakarārangi hototahi ki te korehau.
Ātete ki te Irahiko:
Mō ngā tono e pā ana ki te irahiko whakakoi (ngā pūnaha ātea, ngā whare karihi, ngā taputapu hihi-X), ka taea e te pōuri i puta mai i te irahiko te whakaiti i te tukunga whatu. Kei te wātea ngā karāhe mārō irahiko, engari he pai rawa te ātete o te silica kua hanumihia:
- Hiraka hanumi: Kāore he mate tuku ine tae atu ki te 10 krad horopeta katoa
- N-BK7: Ngaronga tuku <1% i te 400 nm i muri i te 1 krad
Te Pūmautanga mō te Wā Roa:
Ko te pānga whakaemi o ngā āhuatanga matū me te taiao e whakatau ana i te pumau mō te wā roa. Mō ngā papa whakarārangi tika:
- Te silica kua hanumi: Te pumau o te rahinga < 1 nm ia tau i raro i ngā āhuatanga taiwhanga noa
- Zerodur®: Te pumau o ngā āhuatanga < 0.1 nm ia tau (nā te pumau o te āhua tioata)
- Konumohe: Te nekenekehanga o te whānuitanga 10-100 nm ia tau nā te whakangāwari o te ahotea me te huringa wera
Taupānga o te Ao Tūturu:
He kamupene rongoā e whakahaere ana i ngā pūnaha whakatikatika whatu mō te tirotiro aunoa i roto i te taiao rūma ma me te horoinga IPA o ia rā. I te tīmatanga i whakamahia e rātou ngā wāhanga whatu kirihou, i pāngia rātou e te pirau o te mata e hiahiatia ana kia whakakapia i ia 6 marama. Nā te huri ki ngā papa karaihe borofloat®33 i roa ake ai te roa o te oranga o te wāhanga ki te neke atu i te 5 tau, i whakaitihia ai ngā utu tiaki mā te 80% me te whakakore i te wā kore mahi i whakaritea nā te pirau whatu.
