Case Overview

Case Results

Sichuan University

"LaSense Technology Ultra Low Noise Laser Driver is one of our preferred devices for accurate acquisition of molecular absorption spectra. Its precise temperature control and ultra-low electronic noise make it possible to detect spectra with high precision and help us expand the number of gas parameters that can be resolved, from the original temperature and component concentration to the current level. Simultaneous measurements of temperature, component concentration, pressure, and many more spectral parameters are now available, providing excellent technical support for our TDLAS multi-parameter measurement solution."


Changguang Institute (Chunguang Institute, Dean of Chinese Science)

"As a fundamental component of precision optical experiments, LaSense's laser driver performs well in our optical and spectroscopy experiments. Its low noise design effectively reduces the experimental background noise and greatly improves the detection sensitivity. The modular interface is also very friendly and can be easily integrated into our optical systems."



Wuhan University of Technology

"In laser absorption spectroscopy experiments, we need easy-to-use and portable distributed feedback laser drivers for system construction and teaching demonstration experiments. For students with non-electrical background, LaSense controller reduces the tedious welding line, limit setting, testing and other operations, making the experiment efficiency is greatly improved."

 

Harbin Institute of Technology

"When performing precision spectroscopy experiments at low temperatures, we found that LaSense Ultra Low Noise Laser Driver was able to maintain stable output performance and impressive temperature control accuracy. This product simplifies commissioning in our lab and supports high-quality data acquisition."
