About Us
AD111是计算机控制的光电倍增管探测系统,可以和Spectral Products的Digikrom单色仪一起使用。它由一个阳极相连的电子倍增电极链构成探测器封装,正对Digikrom 单色仪的输出狭缝固定,侧方可以放置光电倍增管(需另外购买)。同时,它也包含了倍增管放大器,这是个完整的电子单元包括了前置放大器和PMT所需高压电源。PMT高压电源线盒信号输出线连接了探测器封装和放大器单元。整个工作过程,包括波长和带通选择,都通过客户自己的计算机控制(Digikrom单色仪采用一个串口,AD111采用一个USB口。PMT和单色仪的所有功能都可以通过一个便于使用的软件实现。软件可以图形化地显示波长和强度,以及强度和时间的关系,并允许将ASCII数据存储并传输到其它客户所需的界面。
The AD111 is a convenient computer controlled photomultiplier detection system for use with Spectral Products’ Digikrom line of monochromators. It features a detector housing that has a dynode divider chain and direct anode connection, mounts directly to exit-slit ports of Digikrom monochromators, and accommodates side-on photomultiplier tubes. (PMT’s must be ordered separately.) It also features the Photomultiplier Amplifier, a compact electronic unit containing the preamplifier and high voltage power supply for the PMT. Coaxial cables for the high voltage and PMT output current signals connect between the detector housing and the amplifier unit. The entire operation, including wavelength and bandpass selection, is controlled with a customer-supplied PC. (The Digikrom monochromator and the AD111 utilize one serial for monochromator and one USB port for AD111) An easy to use program is also included that allows full control of both PMT and monochromator. It graphically displays wavelength versus intensity, intensity versus time and allows ASCII data storage for importing to other user interfaces as desired.
