Ko te whakakotahi muka whakaata a Thorlabs e hangai ana i tētahi whakaata paraboloid (OAP) 90° kei waho o te tuaka me te roa arotahi pumau i runga i te awhe roangaru whānui, ā, he mea tino pai mō te whakamahi i roto i ngā pūnaha e hiahia ana kia whakakotahihia ngā roangaru maha.
E toru ngā hoahoa whare o te collimator whakaata, e hototahi ana ia ki ngā peke muka me ngā hononga FC/PC, FC/APC, SMA rānei.
Ngā Kaupapa Taketake o te Whakaata OAP
Ko te Whakaata OAP (Off-Axis Parabolic) tētahi wāhanga o tōna parabolic matua.
Ko te tikanga o te tuaka-kore he whakarara ngā tuaka whatu o ngā mea e rua engari kāore e ōrite ana.
Ka haere te tuaka arotahi mā waenganui o te arotahi me te Whakaata OAP,ā, ko te tawhiti i waenganui i ēnei pūwāhi e rua ka kiia ko te roa arotahi whakaata(RFL).
Ko te koki i waenganui i te tuaka arotahi me te tuaka whatu ko te koki kei waho o te tuaka,e 90 ngā nekehanga i konei.
Pūmau Whakapūmau
E rua ngā kiriata whakarewa whakaata teitei e whakaratohia ana e ngā collimator muka pumau: -F01 UV-kiriata konumohe whakarei ake me te kiriata hiriwa -P01 me te paparanga tiaki, ee taunakitia ana mō te whakakotahi muka aratau-kotahi me te aratau-maha, me tengā tono hononga muka aratau maha.
E ai ki te diameter o te kurupae kua whakapūmautia (mō te muka 0.13 NA), ka taea ēneiwehea ki ngā raupapa e whā e whai ake nei:
Ko ngā pikitia e whā i runga ake nei ko RC02FC-P01, RC04FC-P01, RC08APC-P01 meRC12SMA-P01 ia.
Nō reira, e ai ki te tauira hua, ka taea e tātou te mōhio ki ngā tawhā matuao ia whakakoi whakaata, tae atu ki te diameter kurupae whakakoi, te mukahononga me te paninga.
He hototahi ngā collimator RC02, RC04, me RC08 ki ngā SM05- o roto.ngā maunga miro, i te mea e hototahi ana te collimator RC12 ki te SM1- o rotongā whakairi miro.
Hei tāpiritanga, ka taea te whakairi tika i te collimator RC02 ki roto i te Ø1/2"te maunga kinematic, i te mea ka taea te whakairi tika i te RC02, RC04, me te RC08 ki te pitoki roto i te maunga kinematic Ø1" (whai muri i te wetewete tuatahi i te mowhiti knurled i runga i te kore ututauranga mokowā);
Mā te whakairi ki te maunga kinematic ka taea te whakarite i te kurupae ina honoa te mukae hiahiatia ana.
Kaiwhakakotahi Iti
Ka tutuki i te collimator iti tētahi hoahoa angiangi ake mā te whakauru i te whakaata ki roto i tete taha whakamuri ki mua. Ka taea te wehewehe kia rua ngā raupapa e ai kite roa arotahi: RCR25x-P01 me RCR50x-P01, me ngā roa arotahi whakaatao te 25.4 me te 50.8 mm ia; ko te x i roto i te tau tauira ko te mukamomo hononga, ka taea te whakakapi ki te P, A me te S hei tohu i te FC/PC,Ngā hononga FC/APC me SMA.
Ka taea te whakairi tika i ngā collimator iti ki roto i ngā maunga ngongo arotahi Ø1/2", pērā ihei mowhiti paheke SM05RC(/M) me te rawhi SM05TC.
Mena e hiahiatia ana he whakatikatika i te pitch/yaw, ka taea te whakairi ki roto i te kinematic Ø1".tāuta mā te whakamahi i te urutau SM1A60.
Ka taea hoki te whakauru tika i te collimator iti ki roto i te whare herehere 16 mm.pūnaha mā te whakamahi i tētahi pereti whare herehere SP3, i tētahi poraka whare herehere SC6W rānei, ki roto rānei i tētahi pouaka 30 mmpūnaha whare herehere mā te whakamahi i tētahi urutau SM1A60 me tētahi poraka whare herehere C4W.
Kaiwhakarite Whakarerekē
Ka taea e ngā taputapu whakarara whakarerekē te whakarerekē i te tawhiti mai i te muka ki te whakaata OAP hei arotau i te whakarara o ia muka, hei hono rānei i te mārama ki ngā muka aratau kotahi, ki ngā muka aratau maha rānei.
Ina whakaritea te rārangi kua tuhia ki te tohu ∞, ko te tawhiti mai i te mukaki te whakaata OAP he ōrite ki te RFL, ā, ka whakaputa te collimator i tētahikurupae kua whakapūmautia (i runga ake nei).
Ina peka ke te rārangi kua tuhia mai i te tohu ∞, ka whakaputa te collimator i tētahihihi wehewehe, hihi whakatakotoranga rānei, me te tawhiti mōrahi mai i tōna arotahi kiko te pokapū o te whakaata he -2.2 m me te 0.15 m, ia, e whakaaturia ana i roto i tee whai ana i ngā āhua e rua.
Ina ōrite te ōwehenga honohono ki te mutunga kore, ka taea e ngā whakaata OAP te whakatutukiwhakaahua e herea ana e te diffraction.
E ai ki te pikitia i raro nei, e rua ngā kaitahuri whakaata ka taea te whakaritehe tino pai mō te hononga tawhiti, kia taea ai te wāhi kore-waengaka taea te urungi i te hihi me ētahi atu huānga whatu, he mea tino whai hua i roto ingā tono whakawhitiwhiti kōrero tawhiti.
Ka taea te whakairi i te collimator whakarerekētanga RCF15x-P01 ki roto i te reti SM1RC(/M)mowhiti, te rawhi ringaringa SM1TC rānei mā te whakamahi i te wāhanga pango.
Mō te whakatikatika i te piko/te piko o te mata, e taunakihia ana kia whakamahia he pūmau Polaris, pērā i tete POLARIS-K2, te POLARIS-K2VS2L Ø2" rānei te maunga kinematic mā te whakamahi i te AD2Turutau; te maunga kinematic miro-POLARIS-K2T SM2 mā te whakamahi i te SM2A21urutau; te POLARIS-K15XY rānei te maunga kinematic tuaka-5 mā te whakamahi i te SM1L03ngongo arotahi me te urutau SM1A68.
Ko te pito wāhi-kore o te whare collimator whakarerekē kua mirohia kingā miro SM05 ā-roto me ngā miro SM1 o waho.
Ngā tauira o te tāutanga o te collimatore whakaaturia ana i ngā whakaahua e rua e whai ake nei.
Te Whakakotahitanga Muka Aratau Kotahi
I te wā e whakakoi ana i ngā muka aratau-kotahi, ka puta he whānui o ēnei whakakoi whakaata-hope, ngā kurupae iti-rerekētanga.
Ka taea te whakatau tata i te rerekētanga katoa o te kurupae kua whakapūmautia (i roto i ngā nekehanga)mā te whānui o te mara aratau muka (MFD) me te roa arotahi whakaata (RFL):
Ko te whānui 1/e² o tētahi kurupae kua whakapūmautia he tata ki:
Hei tauira, mā te whakamahi i te kaiwhakakotahi iti RCR25A-P01 hei whakakotahi i te P3-630A-FC-1 muka aratau-kotahi, i te roangaru o λ = 633 nm, ko te MFD he 4.3µm.
E whakaatu ana ngā whārite e rua i runga ake nei ko te koki wehewehenga he 0.01 nekehanga, ā, ko te whānui o te kurupae he 4.8 mm.
Te Whakakotahitanga Muka Aratau Maha
Ko te koki wehewehenga katoa o te kurupae kua whakapūmauhia he tata ki:
Ko te whānui o te kurupae kua whakakorikoria tata ki:
Kāore te putanga o te muka aratau maha i te tino pai te honohono.
E ai ki te tātai i runga ake nei, ko te whānui o te kurupae te mea nui e pāngia ana e te NAi tētahi tūranga e tata ana ki te whakaata OAP, engari i te horapa o te hihi, kaka nui haere te mārama o te awe o te diameter o te uho.
Mō te kaiwhakakotahi pumau kua whakahuatia i runga ake nei, ko te diameter o te kurupae kua whakakotahitia koi tatauhia mā te 2NA*RFL, he nui ake i te 1/e² te whānui o te kurupae.
I te wā e whiriwhiri ana i tētahi kaitahuri pūmau, ka taea te whakatau i te roa o te arotahi mai i tete diameter e hiahiatia ana hei whakatau i te tauira e tika ana.
E rua ngā herenga nui ki te whakakotahi i ngā muka aratau maha.
Tuatahi, ko te nuinga o ngā muka maha-aratau he hihi putanga tino rerekē ka taea tekua āraia e te whare i mua i te taenga atu ki te whakaata OAP, nō reira ko te muka NAkāore e taea te neke atu i tētahi uara kua whakaritea; tirohia te ripanga o mua mō ētahi atu kōrero.
Tuarua, ko te rerekētanga o te hihi kua whakapūmautia e pā ana ki te uhote whānui; i te pikinga ake o te whānui o te matua, ko te NA mōrahi e tautokona ana eka heke te pūwhakakoi.
Mena ka nui ake te whānui o te hihi kua whakapūmautia i te pūaha mārama, ka nui ake te putangaka āraia te kurupae e te whare.
Ka taea e ēnei āhuatanga e rua te whakaheke i te kounga o ngā hihi.
Hei tāpiritanga, ka taea anake e ngā whakaata OAP te whakakotahi pai i ngā pūtake pūwāhi i tepūwāhi arotahi.
Ko te nui ake o te pekanga o te pūtake pūwāhi mai i te tuaka whatu, ko tete nui ake o te diameter matua aratau maha, ka nui ake te hē o te collimatedhihi; mā te whakanui ake i te roa arotahi whakaata, i te roanga ngaru rānei, ka taea te whakaiti i tewhakapōturitanga
