Noocyada eemuraayada warshadahabuurta

Inta badan waxaa jira afar nooc oo interface ah, oo kala ah F-Mount, C-Mount, CS-Mount iyo M12 mount. F-Mount-ku waa is-dhexgal ujeedo-guud ah, wuxuuna guud ahaan ku habboon yahay muraayadaha dhererkoodu ka dheer yahay 25mm. Marka dhererka isha ee muraayadda ujeedadu ay ka yar tahay 25mm, sababtoo ah cabbirka yar ee muraayadda ujeedada, C-Mount ama CS-Mount ayaa la isticmaalaa, qaarna waxay isticmaalaan interface M12.

Farqiga u dhexeeya C mount iyo CS mount

Farqiga u dhexeeya C iyo CS interfaces ayaa ah in masaafada u dhexeysa korka xiriirka ee lens-ka iyo kamarada ilaa diyaaradda focal ee lens-ka (meesha uu CCD photoelectric sensor ee kamaradu tahay) waa ka duwan yahay. Fogaanta C-Mount interface waa 17.53mm.

Giraanta adabtarada 5mm C/CS waxaa lagu dari karaa lenska CS-Mount, si loogu isticmaalo kamaradaha nooca C-ga ah.

Xuduudaha aasaasiga ah ee muraayadaha warshadaha

Goobta muuqaalka (FOV):

FOV waxaa loola jeedaa kala duwanaanshaha muuqda ee shayga la arkay, taas oo ah, qaybta shayga uu qabtay shidma kamaradu. (Baaxadda goobta aragtida waa wax ay tahay in la fahmo xulashada)

Goobta aragtida

Fogaanta Shaqada (WD):

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

Qaraarka

Cabbirka sifada ugu yar ee lagu kala saari karo shayga la baaray kaas oo lagu cabbiri karo nidaamka sawir-qaadista. Inta badan, goobta yar ee aragtida, ayaa si fiican u xallinta.

Qoto dheer ee aragtida (DOF):

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

Halbeegyada kale eemuraayadaha warshadaha

Cabbirka jajabka xasaasiga ah:

Cabbirka aagga waxtarka leh ee chip shidma kamarada, guud ahaan waxa loola jeedaa cabbirka jiifka. Halbeeggani aad buu muhiim u yahay si loo go'aamiyo cabirka lens-ka saxda ah si loo helo goobta la rabo ee aragtida. Saamiga weynaynta muraayadaha aasaasiga ah (PMAG) waxaa lagu qeexaa saamiga cabbirka jilibka dareemayaasha iyo goobta muuqaalka. In kasta oo cabbirrada aasaasiga ah ay ku jiraan cabbirka iyo goobta muuqaalka ee chip-ka sawir-qaadista, PMAG maaha halbeeg aasaasi ah.

Cabbirka chip xasaasiga ah

Dhererka fog (f):

Dhererka fooxa waa cabbirka diiradda ama kala duwanaanshaha iftiinka ee nidaamka indhaha, taas oo tixraacaysa fogaanta u jirta xarunta indhaha ee muraayadda ilaa diiradda ururinta iftiinka. Sidoo kale waa fogaanta u jirta bartamaha muraayadda ilaa diyaaradda sawir-qaadista sida filimka ama CCD ee kamarada. f={masaafo shaqo/ganacsiga aragtida dhinac dheer (ama dhinac gaaban)}XCCD dhinac dheer (ama dhinac gaaban)

Saamaynta dhererka focal: inta yar ee dhererka focal, ayaa ka sii weyn qoto dheer ee beerta; Inta yar ee dhererka focal, ayaa sii weynaan doonta qallooca; Inta yar ee dhererka xudunta u ah, waa ka sii daran ifafaale vignetting, taas oo yaraynaysaa iftiinka cidhifka aberration.

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

Habka xisaabinta ee kore waxay si aragti ahaan u xisaabin kartaa xallinta, laakiin kuma jirto qallooc.

Qallooc:

Mid ka mid ah tilmaamayaasha lagu cabbirayo waxqabadka muraayadda ayaa ah aberration. Waxay tilmaamaysaa xariiqda tooska ah ee ka baxsan dhidibka ugu weyn ee diyaaradda mawduuca, kaas oo noqda qalooc ka dib markii lagu sawiray nidaamka indhaha. Khaladka sawir-qaadista ee habkan indhaha waxa loo yaqaan qallooc. Qalloocyada qalloocan waxay saameeyaan joomatari sawirka oo kaliya, ma saameeyaan muuqaalka sawirka.

Aperture iyo F-Lambarka:

Xaashiyaha lenticular waa aalad loo isticmaalo in lagu xakameeyo cadadka iftiinka dhex mara muraayadda, inta badan gudaha muraayadda. Waxaan isticmaalnaa qiimaha F si aan u muujinno cabbirka daloolka, sida f1.4, F2.0, F2.8, iwm.

Aperture iyo F-Lambarka

Weyneynta indhaha:

Habka loo isticmaalo in lagu xisaabiyo saamiga ugu weyn ee miisaanku waa sida soo socota: PMAG = cabbirka dareemayaasha (mm) / goobta muuqaalka (mm)

Muujinta weyneynta

Weyneynta muujinta ayaa si weyn loogu isticmaalaa microscopy. Weyneynta bandhigga shayga la cabbiray waxay ku xiran tahay saddex arrimood: weyneynta indhaha ee lens-ka, cabbirka qalabka dareemayaasha ee kamarada warshadaha (cabirka dusha sare ee bartilmaameedka), iyo cabbirka bandhigga.

Muujinta weyneynta = weyneynta muraayadaha indhaha × cabbirka cabbirka × 25.4 / cabbir cabbirka rake

Qaybaha ugu muhiimsan ee muraayadaha warshadaha

Kala soocidda

• Marka loo eego dhererka fog: ugu muhiimsan iyo zoom

• Aperture: dalool go'an iyo dalool doorsooma

•Interface: C interface, CS interface, F interface, iwm.

• Waxaa loo qaybiyaa dhufasho: lens-weyneyn go'an, lens zoom joogto ah

Lenses-yada aadka muhiimka ah ee sida caadiga ah loo isticmaalo warshadaha aragga mashiinka waxa ka mid ah lenses-yada FA, lenses telecentric iyo mikroskoobyada warshadaha, iwm.

Qodobbada ugu muhiimsan ee ay tahay in lagu xisaabtamo doorashada amuraayada aragga mashiinka:

1. Goobta muuqaalka, weyneynta indhaha iyo masaafada shaqada ee la rabo: Marka la dooranayo muraayadda, waxaan dooran doonaa muraayad leh muuqaal wax yar ka weyn shayga la cabbirayo, si loo fududeeyo xakamaynta dhaqdhaqaaqa.

2. Qoto dheer ee shuruudaha goobta: Mashaariicda u baahan qoto dheer, isticmaal dalool yar intii suurtogal ah; markaad dooranayso lens-weynayn leh, dooro muraayad weynayn yar ilaa inta mashruucu ogolyahay. Haddii shuruudaha mashruucu aad u baahan yahay, waxaan u muuqdaa inaan doorto muraayad-goyn leh oo qoto dheer oo qotodheer ah.

3. Cabbirka dareemayaasha iyo is-dhexgalka kamarada: Tusaale ahaan, lenska 2/3" wuxuu taageeraa dusha sare ee kamarad warshadeed ee ugu weyn waa 2/3", ma taageeri karto kamaradaha warshadaha ee ka weyn 1 inch.

4. Meel bannaan: Waa wax aan macquul ahayn in macaamiisha ay beddelaan cabbirka qalabka marka nidaamku yahay ikhtiyaari.
