T92+ Spectrophotometer 分光度計

The T92+ wavelength range is 190–900nm and the instrument has a User Defined Variable Bandpass from 0.1nm – 5.0nm. The photo metric range is -4 to +4 Abs.

T92波長范圍為190~900 nm,儀器具有用戶定義的0.1nm~5.0nm的可變帶通。攝影測量范圍是-4到4 Abs

具有全息光柵的Czerny-Turner單色器使雜散光保持最小并提供極好的光學分辨率。

光電倍增管作為檢測器的使用提供了卓越的靈敏度

T92的真雙光束光學系統與高效且成熟可靠的電子控制系統相耦合,確保了高穩(wěn)定性和低背景噪聲
