Noocyada eeMuraayadaha warshadaharakibid

Inta badan waxaa jira afar nooc oo is-dhexgal ah, kuwaas oo kala ah F-mount, C-mount, CS-mount iyo M12 mount. F-mount waa is-dhexgal guud, guud ahaanna wuxuu ku habboon yahay muraayadaha leh dherer focal ah oo ka dheer 25mm. Marka dhererka focal ee muraayadda object uu ka yar yahay qiyaastii 25mm, sababtoo ah cabbirka yar ee muraayadda object, C-mount ama CS-mount ayaa la isticmaalaa, qaarna waxay isticmaalaan is-dhexgalka M12.

Farqiga u dhexeeya C iyo CS

Farqiga u dhexeeya is-dhexgalka C iyo CS waa in masaafada u dhaxaysa dusha sare ee taabashada muraayadda iyo kamaradda ilaa meesha ugu sarreysa ee muraayadda (meesha ay tahay in dareemaha sawir-qaadista ee CCD ee kamaraddu uu ahaado) ay kala duwan tahay. Masaafada is-dhexgalka C-mount waa 17.53mm.

Giraangiraha adabtarada 5mm C/CS ayaa lagu dari karaa muraayadda CS-mount, si loogu isticmaalo kamaradaha nooca C-ga ah.

Xuduudaha aasaasiga ah ee muraayadaha warshadaha

Goobta aragtida (FOV):

FOV waxa loola jeedaa baaxadda muuqata ee shayga la arkay, taas oo ah, qaybta shayga ee uu qabtay dareemaha kamarada. (Baaxadda goobta aragtida waa wax ay tahay in lagu fahmo xulashada)

Goobta aragtida

Masaafada Shaqada (WD):

Waxay tilmaamaysaa masaafada u dhaxaysa hore ee muraayadda ilaa shayga la tijaabinayo. Taasi waa, masaafada dusha sare ee sawir-qaadista cad.

Xallinta:

Cabbirka ugu yar ee lagu kala saari karo shayga la baaray ee lagu cabbiri karo nidaamka sawir-qaadista. Inta badan, marka muuqaalka yar yahay, ayaa xallinta ka sii fiican.

Aragtida qoto dheer (DOF):

Awoodda muraayadda si ay u ilaaliso xalka la rabo marka walxaha ay ka dhow yihiin ama ka fog yihiin diiradda ugu fiican.

Xuduudaha kale eeMuraayadaha warshadaha

Cabbirka jajabka sawir-qaadista:

Cabbirka aagga wax ku oolka ah ee jajabka dareemaha kamarada, guud ahaan wuxuu tilmaamayaa cabbirka toosan. Halbeeggan aad ayuu muhiim u yahay si loo go'aamiyo cabbirka muraayadda saxda ah si loo helo aragtida la rabo. Saamiga weyneynta koowaad ee muraayadda (PMAG) waxaa lagu qeexaa saamiga cabbirka jajabka dareemaha iyo goobta aragtida. Inkasta oo xuduudaha aasaasiga ah ay ku jiraan cabbirka iyo goobta aragtida jajabka xasaasiga ah, PMAG maaha halbeeg aasaasi ah.

Dhererka diiradda (f):

"Dhererka diiradda waa cabbiraadda isku-darka ama kala-duwanaanta iftiinka ee nidaamka indhaha, kaas oo tilmaamaya masaafada laga bilaabo xarunta indhaha ee muraayadda ilaa diiradda ururinta iftiinka. Sidoo kale waa masaafada laga bilaabo bartamaha muraayadda ilaa diyaaradda sawirka sida filimka ama CCD ee kamaradda. f={masaafada shaqada/goobta aragtida dhinaca dheer (ama dhinaca gaaban)}XCCD dhinaca dheer (ama dhinaca gaaban)

Saamaynta dhererka diiradda: dhererka diiradda oo yar, qoto dheeraanta goobta ayaa sii weynaanaysa; dhererka diiradda oo yar, ayaa sii weynaanaysa qallooca; dhererka diiradda oo yar, ayaa sii weynaanaysa ifafaalaha muujinta, kaas oo yareeya iftiinka geeska isbeddelka.

Xallinta:

Waxay tilmaamaysaa masaafada ugu yar ee u dhaxaysa 2 dhibcood oo lagu arki karo muraayado ujeedo leh

0.61x hirarka la isticmaalay (λ) / NA = xallinta (μ)

Habka xisaabinta ee kor ku xusan wuxuu si aragti ahaan u xisaabin karaa xallinta, laakiin kuma jiraan qallooc.

※ Mowjadda la isticmaalay waa 550nm

Qeexitaan:

Tirada xariiqyada madow iyo caddaanka ah waxaa lagu arki karaa bartamaha 1mm. Cutubka (lp)/mm.

qallooc:

Mid ka mid ah tilmaamayaasha lagu cabbiro waxqabadka muraayadda waa cillad. Waxay tilmaamaysaa xariiqda toosan ee ka baxsan dhidibka ugu weyn ee diyaaradda qofka, taasoo noqota qalooc ka dib marka uu sawirto nidaamka indhaha. Khaladka sawir-qaadista ee nidaamkan indhaha waxaa loo yaqaan qalooc. Khaladaadka qallooca waxay saameeyaan oo keliya joomatari ee sawirka, ee ma aha fiiqan sawirka.

Daloolada iyo Lambarka F:

Xaashida lenticular waa qalab loo isticmaalo in lagu xakameeyo xaddiga iftiinka ee dhex mara muraayadda, badanaa gudaha muraayadda. Waxaan isticmaalnaa qiimaha F si aan u muujinno cabbirka daloolka, sida f1.4, F2.0, F2.8, iwm.

Daloolada iyo F-Lambarka

Weyneynta indhaha:

Qaacidada loo isticmaalo in lagu xisaabiyo saamiga cabbirka ugu weyn waa sidan soo socota: PMAG = cabbirka dareemaha (mm) / goobta aragtida (mm)

Weyneynta bandhigga

Weyneynta bandhigga waxaa si weyn loogu isticmaalaa mikroskoobka. Weyneynta bandhigga ee shayga la cabbiray waxay ku xiran tahay saddex arrimood: weyneynta indhaha ee muraayadda, cabbirka jajabka dareemayaasha ee kamaradda warshadaha (cabirka dusha sare ee bartilmaameedka), iyo cabbirka shaashadda.

Weynaynta bandhigga = weynaynta indhaha ee muraayadda × cabbirka bandhigga × 25.4 / cabbirka xagasha

Qaybaha ugu muhiimsan ee muraayadaha warshadaha

Kala-soocidda

•Dhererka diiradda: ra'yiga ugu sarreeya iyo zoom-ka

• Iyada oo loo marayo daloolka: dalool go'an iyo dalool doorsoome ah

• Iyada oo loo marayo interface: C interface, CS interface, F interface, iwm.

• Loo qaybiyay dhowr jeer: muraayad weyneyn go'an, muraayad si joogto ah loo soo bandhigo

• Muraayadaha aadka muhiimka u ah ee badanaa loo isticmaalo warshadaha aragga mashiinka waxaa ka mid ah muraayadaha FA-ga, muraayadaha telecentric-ga iyo mikroskoobyada warshadaha, iwm.

Qodobbada ugu muhiimsan ee ay tahay in la tixgeliyo marka la dooranayomuraayadda aragga mashiinka:

1. Goobta aragtida, weynaynta indhaha iyo masaafada shaqada ee la rabo: Marka aan dooranayno muraayad, waxaan dooran doonnaa muraayad leh aragti ka weyn shayga la cabbirayo, si loo fududeeyo xakamaynta dhaqdhaqaaqa.

2. Shuruudaha Qotoda dheer ee goobta: Mashaariicda u baahan qoto dheer ee goobta, isticmaal dalool yar intii suurtagal ah; marka aad dooranayso muraayad leh weynayn, dooro muraayad leh weynayn hoose ilaa inta mashruucu ogol yahay. Haddii shuruudaha mashruucu ay aad u adag yihiin, waxaan u janjeeraa inaan doorto muraayad casri ah oo leh qoto dheer oo goob ah.

3. Cabbirka dareemaha iyo isku xirka kamarada: Tusaale ahaan, muraayadda 2/3″ waxay taageertaa dusha sare ee kamarada warshadaha ugu weyn waa 2/3″, ma taageeri karto kamaradaha warshadaha ee ka weyn 1 inji.

4. Boos bannaan: Macaamiishu waa wax aan macquul ahayn inay beddelaan cabbirka qalabka marka qorshuhu yahay mid ikhtiyaari ah.
