What can the new low cost AVT GoldEye Short Wave Infrared ( SWIR ) camera do for you?

Allied Vision Goldeye cameras with InGaAs sensor technology enables you to see further into the infrared spectral range than classic CCD / CMOS cameras.  Due to the cameras high sensitivity in the Short Wave InfraRed (SWIR) range of 900-1700 nm, new applications become possible.








What applications can be solved with SWIR?

SWIR cameras help provide contrast and emphasize features in various applications due to the nature of the wavelengths.  Applications ranging from agricultural (food), textile, semiconductor and surveillance, allows the ability to see through materials that are opaque to the eye with SWIR.

Several models are available to help solve these applications.   

Goldeye cameras are now available with Camera link interfaces in addition to GigE and are low cost!    Contact us for a quote!

The following are a few examples of Short Wave InfraRed (SWIR ) applications:


Solar Cell Inspection

Light emitted by silicon in solar cells peak at 1150nm and are impossible to detect using normal CCD/CMOS cameras.  


Using SWIR cameras, luminescent imaging helps identify non uniformities at 1150nm  



Semiconductor Inspection 

At wavelengths above 1100 nm silicon becomes transparent.


In turn, SWIR cameras are perfect for analyzing metallization and electrical contact errors on the backside of wafers.

Surveillance Applications

SWIR cameras minimize fog and smoke in surveillance applications allowing scenes not present in the visible realm to be seen.  





 Other applications include:  Airborne Remote sensing (UAV’s), Food inspection, Moisture Detection, Glass production, Recycling, Scientific & Medical Hyper-spectral imaging, Vision Enhancement and more..    

 


Goldeye Short Wave InfraRed cameras now available with Camera LInk and GigE

Image Sensor Chaos – Sony Pregius vs ON-Semi Python – What is best for my camera application?

Which image sensor and camera is best for my application?

This is total Chaos with so many new sensors!

The image sensor market has rapidly changed in the past year, and has become very chaotic in determining the best image sensor and camera for an application.  

Sony and ON-Semiconductor have both launched a family of image sensors which provide global shutter using advanced CMOS designs resulting in high speed, crisp images.  

These CMOS sensors are now a viable alternative to CCD’s and older CMOS technology, providing higher performance and lower costs.  

BUT.. Which one is most suited for my application?  

Its best to start with understanding what is most important application.  Do we need speed?  Low noise?  Dynamic Range? or maybe a combination of attributes.  

1st Vision has helped make sense of the chaos in providing some considerations and comparisons between the Sony Pregius and ON-Semi Python Series sensors in the following chart.    

 


From the data, you can use these general guidelines

  • If you need the highest speed,  ON-Semi is your choice.   
  • If you need the highest dynamic range, Sony Pregius is your choice.
  • As a great general all around sensor, the Pregius IMX249 sells for ~ $500 in both GigE and USB3  This camera is 2.3MP @ 40fps and can be used in VGA, XGA SXGA modes by setting a ROI.   Read about various resolutions with setting a ROI

Most applications however are not that simple to just choose an image sensor based on speed or dynamic range. In many cases it requires a combination of many factors such as signal to noise, quantum efficiency and saturation capacity.    

1st Vision has more specific data we can discuss with you from various tests we have run and applications solved.  

PLEASE CONTACT US TO DISCUSS YOUR APPLICATION and receive more detailed information.  

Cameras with the Sony Pregius and ON-Semi image sensors continue to expand!  The following links provide a listing of the associated cameras

SVS-Vistek IP67 cameras with direct drive for LED illumination

SVS-VISTEK makes it easier and more cost efficient to integrate industrial cameras for machine vision into harsh environments.  The BlackLine Series ECO and ECO^2 cameras are equipped with water and dust proof housings (IP67 protection) and M12 connectivity for industrial wiring.  This series features direct drive and control of LED illumination from the camera eliminating external controllers. 


These are perfect for industrial automation, robotics and harsh environment applications.  All cameras are GigE Vision compliant and work with 3rd party vision software such as Cognex Vision Pro, National Instruments, Halcon &  MV Tech.  

Key Features for the Blackline Series

  • IP67 Protection
  • M12 Connectivity
  • Direct Drive and Control of LED Illumination with power cables available for CCS LED illumination.

It’s a “No-Brainer” – Why not standardize on 1 camera for less than $500?

In working with many OEM customers of the years, historically several camera models were used to cover multiple system designs.  These were cases where there was an offering of lower and higher resolution systems, in turn needing VGA and 2MP cameras for example.

The introduction of the Sony Pregius sensors have changed the need for multiple cameras given excellent performance and pricing.  It has become a “no-brainer” to think about standardizing on one camera and emulate various resolutions for < $500



1st Vision has reviewed various resolutions achievable within given optical formats using the Sony Pregius IMX174 and IMX249 sensors.  

In cases where we wish to standardize with one camera, we can simply set a Region Of Interest (ROI) and emulate various resolutions (7 in this evaluation). 

We reviewed resolutions from VGA to 2.3MP and have put in perspective to the optical format required.  

The following are several configurations you can achieve: 


2.3MP is achieved using the full frame and 2MP by setting a 1600 x 1200 ROI.  This will require a 1″ optical format lens.  






In cases, where your application only requires 1.3MP (1280 x 1024) or 1.4MP (1400 x 1050), simply set a ROI accordingly and pair with your desired 2/3″ focal length lens.




Simply need 0.5MP (800 x 600) to VGA (640 x 480)? Set your ROI accordingly and you can use any 2/3″, 1/2″ or 1/3″ format lens.








Various resolutions against the required optical format are shown in graphical form to the right and summarized below for the Sony Pregius IMX174 and IMX249 sensors


Once you have your desired resolution, you can calculate your lens focal length using our online calculator.  Using 5.86um as a pixel size, enter the effective number of pixels into the calculator along with working distance (WD) and field of view (FOV).  This will calculate your focal length in which you can then select a lens

The Sony Pregius sensors are featured by several camera manufacturers and expanding rapidly.  With pricing @ < $500 for the IMX249… Its a “No Brainer” to think about standardization!  

Why the big hype on the Sony Pregius Sensors?  These new sensors are becoming the workhorse in imaging with incredible dynamic range, sensitivity and speed.  Learn more in our blog which provides technical details and comparison images.
