Thermal Linescan Cameras - LS 200

The LS 200 is a mid-infrared line scan camera that is particularly suited for thermal imaging of fast moving objects. The LS 200 performs a dual-band line scan of radiation in the mid-infrared range of 1.2 to 4.8 microns. The high frame rate of 400 Hz enables the LS 200 to be used for a wide variety of online imaging applications. It can measure surface temperature without the need for user-supplied emissivity values. Dual wavelength capability also enables applications such as surface detection and measurement of moisture content.

Operating Principle

Radiation enters the inlet port of the line-scan camera through a window mounted on the front. The radiation goes through some optics including a beam-splitter that allows for the instrument�s dual-wavelength capability. The two radiation bands fall side-by-side onto a Lead Selenide detector array; that is sensitive to radiation in the mid-infrared range of 1.2 to 4.8 microns. The detector has a frame scan rate of 400 Hz. The signal from the detector is transmitted to a data acquisition board, and is stored for display and analysis. The spectrometer comes with a data acquisition board system with InfraSpec software installed. The InfraSpec software calculates the relative intensities corresponding to the voltage of each pixel and plots it against the corresponding wavelength falling on each pixel. When referenced, with calibrations obtained using a black body radiation source, the software provides the absolute values of radiation intensities recorded by the detector array.
