LI-COR Biosciences is an international biotech company which designs, manufactures, and markets instruments, measurement systems, and software for biological and environmental research, and develops relevant measurement methodologies and techniques.

[1] LI-COR Biosciences was a privately held company based in Lincoln, Nebraska, until its acquisition by Battery Ventures in 2021.

[9][10] LI-COR also manufactures light sensors, leaf area meters, and plant canopy analyzers,[11] all of which are used to make fundamental measurements in disciplines including plant physiology, climate change, agronomy (forestry and agriculture), and other areas of the natural sciences.

Researchers affiliated with micrometeorological networks around the world use LI-COR carbon dioxide and water vapor analyzers to assess ecosystem greenhouse gas exchange with the eddy covariance technique.

[12] In 2013, the historic benchmark of increase in CO2 concentrations at 400 ppm was reported by the National Oceanic and Atmospheric Administration using LI-7000 Closed Path CO2/H2O gas analyzer.
