超薄型 微型光纖光譜儀 | ATP2400 |
產(chǎn)品概述
集20年的光纖光譜儀研制經(jīng)驗,奧譜天成推出了新一代高性能超薄光纖光譜儀:ATP2400,它內(nèi)置了脈沖氙燈驅(qū)動電路,采用高靈敏度線性CMOS,并特別定制了超低噪聲CMOS信號處理電路,從而大幅降低了傳感器的噪聲,獲得了的信噪比(比同類競爭對手提高了約2倍),而且提高了ATP2400的測量可靠性,測量結(jié)果不隨環(huán)境溫度變化,為業(yè)界水平。ATP2400可接收SMA905光纖輸入光或者自由空間光,通過USB2.0或者UART端口,輸出測量所得的光譜數(shù)據(jù)。
ATP2400只需要一個5V直流電源供電或者USB供電,非常便于集成使用。
