The EM27 represents the most stable and robust open path FT-IR spectrometer on the market with applications focused primarily on ambient air quality monitoring and atmospheric research. Based on the patented, RockSolidTM  corner cube style interferometer, the EM27 provides a highly efficient light collection system, superior detector cooling properties and an internal blackbody calibration source. The system is designed to provide laboratory grade performance in a field deployable package and can be supplied with detectors that are optimized for the specific infrared wavelength region of interest.


New compact spectrometer EM27/SUN for atmospheric measurements by solar absorption spectroscopy.

The EM27/SUN features the new CAMTracker system which is an improved version of the well-know solar tracker utilizing an innovative camera-based feedback system following the sun as light source. The outstanding tracking accuracy is the basis for high-precision quantifications. Additionally the new CAMTracker provides direct line-of-sight information and is insensitive to inhomogenuos illumination. Due to its very compact and robust design, relatively low weight, and intuitive user interface the EM27/SUN is highly portable and ideally suited for long term measurement campaigns in remote areas with little infrastructure.
