SPECTRALINE Therma Line Scan Cameras

Home / Products / Thermal Linescan Cameras

The LS series of Thermal Linescan Cameras was developed by En’Urga Inc. and is marketed by our subsidiary, Spectraline Inc. The LS 200 is a mid-infrared line scan camera that is particularly suited for thermal imaging of fast- moving high- temperature objects. The LS 200 measures the total radiation emitted by the object in the mid-infrared range of 1.2 to 4.8 microns. With the dual- wavelength accessory, the image of the object can be captured at two separate wavelength bands. This enables the estimation of the temperature of the object, independent of its emissivity. US Patent number 6,355,930.

The Lead Selenide detector, used in the thermal line scan cameras detects radiation in the mid-infrared spectrum from 2 microns to 5 microns. The detecting elements experience a change in conductivity caused by incident radiation. This change in conductivity is converted to voltage readings for all pixels. After calibration, the voltages are converted to radiation intensities.
