The SR-5000N IR spectroradiometer is the result of the latest new redesign of the SR 5000, the CI Systems’ flagship product for the last 35 years. The SR 5000N spectroradiometer measures the spectral signatures of objects from a distance which can vary from a few meters to many kilometers. The measurements can be done either spectrally, yielding radiance as function of wavelength or radiometrically to obtain radiance as function of time. The SR5000N is the ideal spectroradiometer for research applications of Remote Sensing, due to the wide spectral range covered (from UV to LWIR), the high sensitivity of the cooled detectors used in the system, and the accuracy of the radiometric calibration based on our state-of-the-art blackbodies. Some instrument parameters (such as field of view, focusing distance, measurement time and others) can be controlled by the user so that, together with the user friendly interface, the work becomes efficient and easy.

Customers who have been using CI Systems' SR-5000 can now increase their measurement capability by getting the latest IR measurement technology with the newly designed SR- 5000N.

The SR-5000N incorporates a wide range of improvements based on the accumulation of experience at CI Systems on the needs of remote sensing measurements over a long period of time and exposure to its customers’ applications.

 These improvements increase usage flexibility and make the work easier and more efficient. The additional features and improvements over the old model are given below. We believe, as a result, that the SR 5000N will be a great addition to the capabilities of your Remote Sensing laboratory 

 

The difference between the SR 5000 and the SR 5000N are:

  • Measurement speed
    The measurement speed in radiometric mode (chopped) is increased by almost a factor of two from 30 to 50 spectral scans/second, while in the transient (unchopped) mode it is improved by a factor of five from 2x104 to 105samples/second.

  • Field of view flatness
    Uniformity of response as function of position of a point source within the field of view of the instrument is called “FOV flatness”. This parameter is significantly improved from about 11% deviation from constancy to a worst case of 5%,where the optics contribution is designed to be only 1%

  • Simultaneous visible and IR spectral measurements of the same object
    Until now it was not possible to measure an object’s spectrum in both visible and infrared ranges simultaneously because these two ranges could be covered only by physically replacing the CVF and the detector in the instrument. Today the SR 5000N has an added visible spectrometer optical channel complete with its own monochromator and detector, in parallel to the CVF IR optical channel.These two channels are pointed into the same direction and they measure the same object simultaneously in one fell swoop.

  • Easier pointing on the object to be measured and background image recording
    In the SR 5000 pointing the instrument field of view on the object to be measured is cumbersome because the user is presented with an upside down, somewhat washed out background image. In the SR 5000N pointing, focusing and image recording is implemented with a  CCD boresighted with the measurement channel line of sight. The background image recorded by this digital camera is easily seen on a large display on the optical head’s back panel before (for pointing) and during the measurement (for later data analysis, measurement set-up recording, etc.).
