Specim Imspector

Overview

ImSpector imaging spectrograph is a component that can be combined with a broad range of monochrome matrix cameras to form a spectral imaging device.
Equipped with an objective lens and coupled with a monochrome area camera, ImSpector converts it to a spectral line imaging camera.
Operation is based on SPECIM's direct sight imaging spectrograph technology. ImSpector captures a line image of a target and disperses light from each line image pixel to spectrum. Each spectral image contains then line pixels in spatial axis and spectral pixels in spectral axis. In consequence it is possible to acquire full spectral information for each line image acquired from the target.
Since ImSpector captures images sequentially of the moving target or by moving itself, a 2D spectral image can be formed. This technology allows diversified opportunities to analyse the target accurately based on its spectral features.
As another way of using, ImSpector can be combined with multichannel fiber optics, so that it becomes a multichannel spectrograph capable of measuring several distributed points simultaneously.

ImSpector Enhanced Series

SPECIM has developed ImSpector Enhanced imaging spectrographs for the most demanding spectral imaging applications.
The Enhanced series meets the requirements when using large size detectors with big amount of small pixels.
These imaging spectrographs are suitable for applications that require high spatial image resolution or simultaneous measurement with large number of optical fibers.
Compared to standard ImSpector series the Enhanced series provides:

  • bigger image size width
  • high resolution (small spot size)
  • smile and keystone distortions in sub-pixel level, and
  • higher throughput.

ImSpector Enhanced imaging spectrographs are constructed as OEM versions.

ImSpector Fast Series

SPECIM has released a new member in the family of ImSpector imaging spectrographs. The new ImSpector Fast10 is a high intensity imaging spectrograph, and makes spectral imaging possible at hundreds and even up to 1500 images per second. ImSpector Fast10 imaging spectrograph provides:

  • high light throughput
  • superior image quality
  • good spectral resolution of 15 nm
  • full VNIR spectrum of 400 - 1000 nm over a narrow dimension, allowing short read out times
  • maximum light intensity on the camera pixels,allowing short integration times
  • high speed acquisition in many low cost industrial CCD and CMOS cameras

ImSpector Fast10 brings spectral imaging to high speed industrial applications, like on line color sorting, and fruit and vegetable inspection.
It also takes airborne hyper-spectral imaging to new speed level.
