Dalsa line scan polarization camera makes invisible visible!

Teledyne Dalsa has released the first line scan polarization camera for machine vision.  The Piranha4 polarization camera provides the capability of detecting , stress, surface roughness,  birefringence and physical properties undetectable with conventional imaging making the invisible visible!

This unique technique uses four polarization channels with a color line scan camera solving various applications, but not limited to the following:

Glass Inspection:  Glass bottles, architectural glass sheets, and automobile windshields, etc. – Enables inspection of internal stress and defects non-visible with conventional imaging

Dalsa Polorized ruler

Film inspection: transparent films, packaging films, and patterned films etc. - Detect scratches, digs, and other surface defects that are difficult to detect with conventional imaging   Dalsa Polarized scratch

Precision optics: optical lens, prisms, fibers, and micro-optical - Detect residual internal stress and thermal annealing effects
polarized - stress in sun glasses

Flat Panel Display and PCB inspection: Thin film transistors, organic LEDs, printed circuit boards etc.- inspect ITO, dust particles, films thickness, and surface defects with enhanced contrast

Carbon fibers: effectively inspect the quality of composite materials that are widely used in aircraft, aerospace, wind energy, and automotive industry

Food and material sorting: Increase sorting accuracy and detecting capability of foreign materials such as plastics, glasses, metals etc. with polarization imaging

Bio-medicine: digital pathology, in vitro cells culture, optical coherence tomography etc.- Provides additional information in birefringence tissues
Remote sensing: helps identifying special objects from natural background
And many more…

Video Tutorial:  How to setup HDR Imaging in Teledyne Dalsa Linea Line scan cameras

Teledyne Dalsa is pleased to announce the release of low cost GigE & Cam Link color Line scan cameras

Teledyne Dalsa is pleased to announce the release of the Linea Color line scan cameras.  

Starting at $1480, the Linea line scan Color cameras are the newest additions to the series built around advanced CMOS technology.  It delivers the best performance to cost ratio in the machine vision industry for color imaging with high speed, high responsivity, low noise and an extensive feature set.  


Feature Highlights: 

  • 2K, 4K and 8K Resolutions available with line rates of up to 48 kHz for 8k Camera link models.  
  • Built in color interpolation in Sapera LT host driver delivers 50% faster speed in RGB full color mode over Spyder 3 color cameras
  • Turbo Drive boosts speeds to achieve line rates that are 2-3X faster than standard GigE vision line rates.
  • AOI and ROI capability outputs and calibrates only regions you are interested in
  • Burst Mode captures the images at faster speeds when sample is passing the FOV and while transmits data during idle time.
  • Smart FFC provides a low pass filter that makes FFC easier without de-focusing the lens
  • White Balance ROI providing only white balance on a small ROI target
  • Noise Filter enables further noise reduction.  
  • LUT for High Dynamic Range Imaging allowing more details to be seen in both bright and dark scenes.  
  • High Dynamic Range (HDR) capable using the cycling mode feature  (See the short video on how to setup this feature )

Dalsa Linea – GigE 80kHz LineScan @ $1100

document.write(" Helvetica, sans-serif; line-height: 15.6933336257935px;">Dalsa's newest innovation is cost!



Introducing Linea, a CMOS line scan camera that can help you improve your imaging and lower your costs. Linea starts with an advanced CMOS sensor with high quantum efficiency and low noise for better images. Linea is also packed with advanced features to make your machine vision job almost effortless.


Linea uses Teledyne DALSA's own advanced CMOS line scan sensors which are available in resolutions from 2k to 16k.




Extensive Feature Set


TurboDrive™ technology allows Linea GigE to deliver its full image quality at line rates up to 80 kHz—several times faster than competitors—with no changes to your GigE network.






    Multiple Regions of Interest to let you reduce your data transfer and processing load — all of which not only help boost performance but also reduce your system cost.







      Burst Modes can take advantage of its high speed sensor by capturing and buffering high speed bursts faster than GigE allows.

      HDR (High Dynamic Range) lets you combine short and long exposures to see details in bright and dark areas at the same time.



      Cycling Mode lets you change your settings every line and cycle through up to five different user-controlled configurations.  This allows use of different light sources, lighting angles, exposure time and gain from a single pass.



      Trigger to Image Reliability framework gives you data reliability peace and of mind by controlling and monitoring the entire image capture process from trigger through image capture and transfer to host memory, protecting you from data loss and improving the reliability of your inspection system.




        Suited for applications in postal, pharmaceutical, print, material and food inspection, Linea is a smart choice with low cost and excellent performance. 

        Full data sheets for linear are available HERE
