產(chǎn)品概述
集20年的光纖光譜儀研制經(jīng)驗(yàn)，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(dòng)電路，采用高靈敏度線性CMOS，并特別定制了超低噪聲CMOS信號(hào)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(jìng)爭(zhēng)對(duì)手提高了約2倍），而且提高了ATP2400的測(cè)量可靠性，測(cè)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(cè)量所得的光譜數(shù)據(jù)。
ATP2400只需要一個(gè)5V直流電源供電或者USB供電，非常便于集成使用。
