What is a diode array detector, the basic structure, advantages and disadvantages, working principles, applications, classifications, operating procedures, and development history of a diode array detector 1

The diode array detector (DAD) is a commonly used optical detector in UCC3895DW, employed for spectroscopic measurements in analytical chemistry, such as infrared spectroscopy, ultraviolet spectroscopy, and fluorescence spectroscopy. It consists of an array of multiple diodes, with each diode corresponding to a detection channel, enabling simultaneous measurement of light signals at multiple wavelengths and achieving multi-channel concurrent detection.diode

I. Basic Structure:

The diode array detector consists of an array made up of multiple diodes. Each diode can independently detect light signals at specific wavelengths. Typically, a diode array detector comprises eight or more diodes, with each diode corresponding to a specific wavelength range. These diodes are usually installed within a sealed metal housing to protect them from external light and environmental interference.
