WiDy SenS 640G-STE

Smart Embedded camera

Plug-and-play, including the option of control of sensor temperature, WiDy SenS GigE cameras are delivered calibrated with an SDK – NITLIBRARY.


  • VGA 640×512, Pitch : 15µm
  • Dual-mode InGaAs sensor (Lin&Log)
  • Near-Infrared Imaging up to 1700nm
  • Dynamic Range 120dB typical in Log, 63dB typical in CTIA (Low Gain), 49dB typical in CTIA (High Gain)
  • TEC on/off
  • Up to 225fps full frame
  • GigE output
  • NUC, BPR & AGC On-board
  • Power Over Ethernet (PoE) option
Sensor format1 inch
Pixel pitch15µm
Partial reading modePossible to integer just a part of the sensor (ROI) and display only this window on the video output. This option allows a frame rate increase on the ROI
Min/Max Settings for display – Histogram StretchingAutomatic/Manual.
In Automatic the gain and offset are calculating depending of the histogram.
In Manual you can choose the gain and offset you want to apply on the image.
NbIgnorePixelsIn percentage of the total number of pixels in the image. Number of pixels ignored for the histogram calculation.
NUC correctionCorrection 1-Point or 2-Point calibrated in factory (possible to realize it also by user)
NUC modeAutomatic/Manual
In manual you can load any NUC calibration file from the flash.
In automatic the camera interpolates the NUC depending of the exposure time.
Bad pixel correctionCorrection of bad pixel calibrated in factory (possible to realize it also by user)
