PFD Spectral Cameras

Hyperspectral Camera operating in the VIS and VNIR ranges of 380-800nm and 400-1000nm. With its high resolution, high image rate, flexible wavelength selection, and rugged structure, Spectral Camera PFD is an excellent tool for industrial measurements.

A Spectral Camera is an imaging spectrometer, an integrated combination of our ImSpector imaging spectrograph and an area monochrome camera. It works as a pushbroom type line-scan camera and provides full, contiguous spectral information for each pixel.

The Spectral Camera PFD consists of an ImSpector V8E or V10E for the wavelength range 380-800nm or 400-1000n, respectively and a high speed CMOS detector. The transmission diffraction grating and lens optics used in the spectrograph provide a hugh quality, low distortion image that is designed to fulfill the most demanding specifications.

This Spectral Camera provides the flexibility and high speed acquisition required in the industrial QC applications. The combination of multiple Region-Of-Interests and binning gives a possibility for the optimal system setup and control for the user. Full spectral range can be acquired with 180 fps at 1312 spatial locations. By selecting partial spectral ranges, speed up to 1000 fps can be achieved.

Gilden Photonics provides various accessories for the spectral cameras to broaden their applicability.

Several fore objective lenses with different FOVs are available which have been designed to provide the optimal image an spectral quality across the full spectral range of the spectral camera

The spectral camera can also be delivered with collection fiber optics to convert the camera into a multiple point spectrometer. All the points are measured simultaneously without a moving multiplexer

The spectral camera can be delivered with a mirror scanner or rotating stage for scanning static targets and outdoor scenes, or with X-stage sample mover for desktop and microscope applications

SpectraSENS software

The camera PFD is supported by the SpectraSENS software, which allows:

  • Data acquisition and saving data in the hard disk
  • Camera parameters settings
  • Basic visualisation in real time
  • Datacubes are saved in the ENVI compatible format that allows further processing by several software packages for hyperspectral data processing
  • Counterfeit detection
