Mission & Vision

Spectraline’s vision is to be at the leading edges of high-speed spectroscopy for industrial process monitoring and research in a variety of fields.

Company Profile & History

Spectraline Inc. was formed as a spin-off in 1999 from parent company, En’Urga Inc. Spectraline’s inception came from a need for a separate entity that would apply En’Urga’s expertise in combustion research, to develop innovative products and bring them to the marketplace, under the Spectraline brand name. 

The first Mid-Infrared Imaging Spectrometer was designed and built for NASA under a SBIR grant by En’Urga Inc. Since then, the technology was developed for research and industrial applications by Spectraline- under license from En'Urga Inc. Spectraline is the embodiment of world-renowned expertise in infrared emission spectroscopy, statistical methods, and analytical instrumentation. 

Two new products, the ES 100 Mid-IR imaging spectrometer, later replaced by the ES200; and, the LS 100 Line Scan camera were introduced in 1999. The LS 200 Line Scan Camera was introduced in 2000. Our latest product, the VS 100 Visible spectrometer was introduced in 2008. 

En’Urga Inc. is well known for its expertise in combustion research and optical diagnostics. En’Urga Inc. and Spectraline Inc. are located in the Purdue University Research Park’s Business and Technology Center. Since its founding in 1994, En’Urga has carried out sponsored research for government agencies and industry worth several million dollars and developed a range of products and technologies.

High temperature parts and processes in industry emit significant amount of radiation in the visible and infrared regions of the spectrum. An accurate method of estimating the temperature of combustor and furnace linings, turbine blades, molten metal and glass are required to ensure quality and to research newer manufacturing methods. Spectraline’s high -speed spectrometers are great tools for measuring radiation emitted by these industrial processes by virtue of their high frame rates, rugged and compact construction. The infrared and visible imaging spectrometers use these non -contact measurements to estimate temperatures, emittances, and concentrations of water vapor, soot, CO2, etc.

Fire, plume, and explosion analysis including temperature and concentration mapping area specialty of the ES series of mid-infrared spectrometers and the LS series of thermal line scan cameras manufactured by Spectraline Inc. The high spectral scan rates enable capture of valuable data for transient events such as explosions and rocket propellant tests while the available 1-D and 2-D scanners enable temperature mapping of pool fires and similar phenomena.

Altogether, Spectraline products are used in a wide variety of applications such as monitoring molten glass, hot steel and aluminum ingots, fault detection in high speed plastic webs and moving parts, characterizing automotive and aerospace engine combustion, pool fires and rocket engine plumes.
