作為全球范圍內(nèi)CCD (ICCD)相機(jī)領(lǐng)域的領(lǐng)軍者,Stanford Computer Optics憑借30多年的經(jīng)驗(yàn),研發(fā)出了全新的超高速相機(jī)4 Picos ICCD相機(jī)。4 Picos的誕生為快速的皮秒時間分辨光譜成像定義了新標(biāo)準(zhǔn)!
4 Picos ICCD相機(jī)采用了超卓越的CCD傳感器和門控圖像增強(qiáng)技術(shù)。它實(shí)現(xiàn)了對單光子的探測,是快速采集頻率和超高靈敏度的優(yōu)越組合。通過超高量子效率(QE)的圖像增強(qiáng)器,以及高達(dá)3.3 MHz的光電陰極選通率(burst),可以獲得極高的檢測性能。極低的抖動、極低的插入式電子門控延遲以及皮秒級別的光學(xué)門控精度,帶來了低至10皮秒無與倫比的時間精度!同時,4 Picos ICCD相機(jī)系列還支持各種主流的觸發(fā)選項(xiàng)和輸入/輸出接口,實(shí)現(xiàn)了復(fù)雜實(shí)驗(yàn)的超精確同步。
