I-IR-CUT Dual Filter Switch ye-CCTV ip Security Camera Lens Projector
Ngaphakathi kwekhamera, i-CCD noma i-CMOS isebenzisa isihlungi sasemini nasebusuku ngoba isithombe sekhamera sinombala ongaphelele emini, umphumela wokukhanya okuphansi kombono wasebusuku awulungile, ngakho-ke isihlungi sasemini nasebusuku asikwazi ukuhlangabezana nokusetshenziswa kwamanje embonini yokuqapha i-CCTV yemikhiqizo yedijithali enencazelo ephezulu, uma ikhamera inombala, izosebenzisa ngokuzenzakalelayo isignali ye-pulse ukwenza iswishi ishintshele kusihlungi se-IR CUT, isuse isithombe sekhamera eduze kwento yemibala eyinhloko, imvelo. Uma ikhamera ibona ebusuku, isebenzisa isignali ye-pulse ukwenza iswishi ishintshele kusihlungi se-AR futhi, lezi zinzwa zesithombe zingadonselwa kuwo wonke ubude bokukhanya, ukuze ikhamera ibe nokukhanya okungcono kanye nesisombululo sesithombe, kwenziwe izinto zibe lula ukuzibona.
Iswishi ye-IR-CUT iyithuluzi elibekwa phakathi kwenzwa yekhamera kanye nelensi, futhi livumela isihlungi se-IR-Cut ukuthi sibekwe noma sisuswe ngaphambili kwenzwa, kuye ngezinga lokukhanya. Iyi-shutter yomshini, evame ukusebenza ngenjini, ene-filter ye-NIR kanye namaphaneli engilazi alula.
Izici Zikagesi:
1. Ukumelana: 25Ω±5Ω (izinga lokushisa elijwayelekile)
2. I-voltage yokushayela: 3.4-4.5V
3. Okwamanje: 155-225mA
Izici Zokukhanya:
1. Ubukhulu bengilazi: T=0.21mm
2. Ubukhulu bengilazi: 8 * 9mm
3. Ukudluliselwa kwengilazi (okubomvu):
| Ubude begagasi | Ukudluliswa |
| 400nm-420nm | T> 82%,I-Tave>88% |
| 420nm-620nm | T>90%, I-Tave>95% |
| 645±10nm | T=50%, ukuthambekelae 80%-20%<20nm |
| 680nm | T<5% |
| 700nm-1050nm | I-Tave<2%, T3% |
| 1050nm-1100nm | I-Tave<2%, T6% |
4, Ingilazi (emhlophe):
400nm-1100nm: T>90%; Tave>92%
Umdwebo Wobuchwepheshe:
Siphinde sinikeze izinsizakalo ezenziwe ngokwezifiso kanye nezinsizakusebenza eziningi zomkhiqizo ukuze zivumelane nezidingo zemakethe ezishintshayo ngezixazululo zobuchwepheshe zokukhanya. Izinhlelo zokusebenza zomkhiqizo zifaka phakathi izimboni, ezokukhiqiza, eze-semiconductor kanye nezokuxhumana.
