Nikon DS-Qi2 科研級螢光專用相機

高靈敏·冷卻式·科研級螢光專用相機

適用於弱訊號的螢光影像拍攝

高畫質影像再加上高靈敏度、低雜訊特性,樣品螢光訊號再弱也不用擔心

 Nikon 全新開發FX-CMOS 大尺寸感光元件

DS-Qi2 使用Nikon單眼相機所使用的FX-CMOS 感光元件及影像技術,大尺寸的感光元件是您影像擷取的絕佳選擇

高靈敏度特性 再弱的螢光也不怕

DS-Qi2 高QE值與低雜訊特性,樣品螢光再弱也能拍出好影像

穩定線性表現

DS-Qi2 線性錯誤率僅±1%,利於量測樣品螢光亮度,或是長時間觀察螢光亮度變化

 

 

 

 

 

 

 

 

 

 

 

Time-lapse images (every 1 second) of LLC-PK1 cells with GFP-EB3 tubulin. Each image represents the maximum intensity projection of the timelapse, allowing visualization of the end-binding protein located on the microtubule plus-ends, and allowing tracing of the microtubule path.
DS-Qi2 captures an extremely large field of view, but still represents very fine details as demonstrated in this cropped timelapse sequence from a large FOV image.

高速Live不再和高解析相衝突

DS-Qi2採用USB3.0傳輸,最高速度每秒可達45張片幅,這使得Live模式下容易對焦,移動樣品影像不產生殘影

更低的雜訊表現

DS-Qi2降溫處理,一舉將ISO拉到51200,高QE值 低雜訊 大的動態範圍優點所拍的螢光影像清晰且細緻
