USB4000-UV-VIS微型光纖光譜儀
USB4000-UV-VIS微型光纖光譜儀可覆蓋200-850 nm的波長范圍,采用3648像素的東芝線性CCD陣列,以增強信噪比和電子特性控制。
USB4000-UV-VIS光譜儀采用"USB"光學平臺。使用可變長通濾光片消除二級和三級衍射的影響,配有25um的入射狹縫以及探測器紫外增強。波長范圍達到200-850nm,光學分辨率為大約1.5nm(FWHM)。

可編程微控制器
USB4000-UV-VIS光譜儀有一個板載的可編程微控制器可對光譜儀及其附件進行控制。通過22針的接口,您可以進行許多操作包括控制外部光源,從外部對象獲取數據。還提供8個可編程的數字I/O端口連接到別的設備。
光學特性
USB4000-UV-VIS光譜儀采用高性能的3648像素線性CCD陣列探測器,整個光學平臺只有手掌那么大。光譜儀接收來自光纖的光能通過固定的狹縫和光柵投射到探測器上,可提供波長范圍在200-850
nm的光譜。
模塊化設計
當您購買了USB4000-UV-VIS光譜儀后,您可以方便的從海洋光學的生產線中尋找您所需要的光學附件。大多數的附件都采用SMA905的接口,您只要簡單地旋出連接器就可以更換或添加采樣附件,包括光源,樣品池,濾光片,流通池,光纖探頭,傳感器,聚焦鏡,衰減器,漫反射標準,積分球和光纖跳線。
即插即用
USB4000-UV-VIS光譜儀可通過USB2.0接口或RS-232串口連接到電腦,PLC和嵌入式系統中。當使用串口通訊時,需要5伏供電。每個光譜儀都有自己特有的參數存貯在光譜儀的內存中,通過光譜儀軟件可以讀出這些數據。
串口操作
當使用串口通訊時,需要5伏供電。光譜儀軟件SpectraSuite并不提供串口的通訊,不過您可以通過串口指令集來編寫您自己控制代碼。
