Introduction to VL-18BitCryoSpectrometer

It adopts 18-bit A/D conversion, featuring a high dynamic range of ≥38000:1 and a high signal-to-noise ratio of ≥1000:1, ensuring that the collected spectral data is accurate and reliable. In addition, the instrument is equipped with various communication interfaces such as USB and serial ports, as well as a 24PIN interaction interface, along with proprietary DAC and ADC, which can easily realize the enabling, intensity control and power feedback of the supporting light source. At the same time, multiple internal sensors are configured, and the software can real-time monitor the optical structure and the internal temperature of the detector, so as to adjust the device status in a timely manner and maintain the stability of detection performance.

In the agricultural field, through sunlight-induced chlorophyll fluorescence detection, it can evaluate plant photosynthesis efficiency, crop growth and yield, and assist in ecological monitoring and climate change research; in the research, development and production of solar cells, it can measure key parameters such as external quantum efficiency (EQE) and internal quantum efficiency (IQE) to support research and development as well as quality control; in gemstone identification, it can detect the transmittance/reflectance of gemstones; in semiconductor manufacturing, it can real-time monitor plasma etching endpoints and parameters by means of optical emission spectroscopy (OES), optimize the process to ensure stability; it can also be used as a core component of a miniaturized Raman spectrometer for Raman spectroscopy detection.
