What is a “TECless” SWIR camera? Learn more about Allied Vision’s highly cost-effective SWIR camera models

SWIR camera

Allied Vision Goldeye SWIR cameraShort Wave Infra-Red (SWIR) imaging is now more economical with the introduction of Allied Vision’s TECless Goldeye cameras.  SWIR cameras open up numerous application possibilities for machine vision solutions, since they are able to detect defects that are not visible to the naked eye.

SWIR cameras have an InGaAs (Indium Gallium Arsenide) sensor that detects wavelengths between 900nm and 1,700nm.  These wavelengths are invisible to the human eye and CCD / CMOS cameras, however SWIR cameras detect the invisible wavelength found in various applications.  For example water accumulations inside fruits or defects within silicon products.

SWIR cameras typically require Thermal Electric Coolers (TEC’s) which enable low-noise imaging in the spectral range of 900mm to 1,700nm.  Additionally, the TEC’s compensate for high temperature fluctuations and stabilizes the image sensor.
For temperature stable environments, Allied Vision now has a “TECless” InGaAs camera providing a lower entry price point, in turn an excellent price-performance ratio.
The Goldeye G-033 and CL-033 TECless InGaAs cameras are the solution to applications unachievable with standard cameras offering the following features
  • SWIR imaging from 900nm to 1700nm
  • High frame rates of 301 fps with VGA resolution
  • Power over Ethernet (PoE)
  • Compact design with no fan
  • Lower cost vs TEC versions
  • GigE and Camera link interfaces.

Learn about CoaXpress and frame rates achievable with Allied Vision’s “Bonito Pro” cameras with CXP-6

Allied Vision Bonito Pro camera

What is  CoaXPress, especially with “CXP-6” capability?

CoaXPress is an established industry standard allowing high speed communications over coaxial cable.  The current version supports bit rates up to 6.25 Gbits/sec over a single coaxial cable.  When used in parallel, two or more coaxial cables can provide incremental speed gains.  The naming convention associated with CoaXPress signify the bit rate as seen in the chart below.   In cases that you see CXP-6 has a bit rate of 6.25 Gb/s.  The 4 x means the number of lanes. Multiply the 2 and you get your total bit rate.

CXP CoaXpress

The new Allied Vision Bonito Pro cameras utilize 4 DIN 1.0/2.3 connectors on a CXP-6 interface (4 lanes) x 6.25Gbits/Sec. This  allows for resolutions of up to 26 megapixels to reach 70 frames per second (fps).  The first two Bonito PRO models (Bonito PRO X-2620 and X-1250) support high resolution with 26.6MP and 12.5MP at 80 and 142 fps respectively.

The Bonito PRO cameras are ideal for a wide range of applications including, 2D/ 3D surface inspection,  high speed printing, PCB & Electronics inspection.

Even faster frame rates can be achieved using the Bonito Pro X1250 (12.5MP) in partial scan mode.  Set to a 768 line height, a rate of 503 fps can be achieved!

Bonito Pro frame rates

The following video’s are good representations of what this relates to in real applications which you can appreciate.

Full specifications for the Allied Vision Bonito Pro cameras can be found HERE, but main features and benefits include:

  • Sensors available in Monochrome (X-1250B) and Color (X-1250C) and extended near-infrared (X1250B NIR ) models
  • On board defect pixel and 2D fixed pattern noise correction for improved image quality
  • Fan-less design for industrial imaging applications.
  • DIN 1.0 / 2.3 CoaXPress connections for secure operation in industrial environments.
  • Single cable solutions using trigger and power over CoaXPress (PoCXP)

CCD vs CMOS industrial cameras – Learn how CMOS image sensors excel over CCD!

CCD vs CMOSCMOS Image sensors used in machine vision industrial cameras are now the image sensor of choice!  But why is this?

Allied Vision conducted a nice comparison between CCD and CMOS cameras showing the advantages in the latest Manta cameras.

Until recently, CCD was generally recommended for better image quality with the following properties:

  • High pixel homogeneity, low fixed pattern noise (FPN)
  • Global shutters for machine vision applications requiring very short exposure times

Where in the past, CMOS image sensors were used due to existing advantages:

  • High frame rate and less power consumption
  • No blooming or smear image artifacts contrary to CCD image sensors
  • High Dynamic Range (HDR) modes for acquisition of contrast rich and extremely bright objects.

Today CMOS image sensors offer many more advantages in industrial cameras versus CCD image sensors as detailed below

Overall key advantages are better image quality than earlier CMOS sensors due to higher sensitivity,  lower dark noise, spatial noise and higher quantum efficiency (QE) as seen in the specifications comparing a CCD and CMOS camera.

CCD vs CMOS comparisonsSony ICX655 CCD vs a Sony IMX264 CMOS sensor

Comparing the specifications between CCD and CMOS  industrial cameras, the advantages are clear.

  • Higher Quantum Efficiency (QE) – 64% vs 49% where higher is better in converting photons to electrons. 
  • Pixel well depth (ue.sat: ) – 10613 electrons (e-) vs 6600 e- where a higher well depth is beneficial
  • Dynamic range (DYN) – Where CMOS provides almost +17 dB more dynamic range.  This is a partial result of the pixel well depth along with low noise.
  • Dark Noise:  CMOS is significantly less vs CCD with only 2 electrons vs 12!

Images are always worth a thousand words!  Below are several comparison images contrasting the latest Allied Vision CMOS industrial cameras vs CCD industrial cameras.

Dynamic Range of today’s CMOS image sensors are contributed to several of the characteristics above and can provide higher fidelity images with better dynamic range and lower dark noise as seen in this image comparison of a couple of electronics parts

Allied vision cmos vs ccdThe comparison above illustrates how higher contrast can be achieved with high dynamic range and low noise in the latest CMOS industrial cameras

  • High noise in the CCD image causes low contrast between characters on the integrated circuit, whereas the CMOS sensor provides higher contrast.
  • Increased Dynamic range from the CMOS image allows darker and brighter areas in an image to be seen.  The battery (left part) is not as saturated vs the CCD image allowing more detail to be observed.

Current CMOS image sensors eliminate several artifacts and provide more useful images for processing.  The images below are an example of a PCB with LEDs illuminated imaged with a CCD vs CMOS industrial camera

ccd vs cmos artifactsCMOS images will result in less blooming of bright areas (LED’s for example in the image), smearing (vertical lines seen in the CCD image) and lower noise (as seen in the darker areas, providing higher overall contrast)

  • Smearing (vertical lines seen in the CCD image) are eliminated with CMOS.  Smear has inherently been a bad artifact of CCDs.
  • Dynamic Range inherent to CMOS sensors allow the LED’s to not saturates as much as the CCD allowing more detail to be seen.
  • Lower noise in the CMOS image, as seen in the bottom line graph shows a cleaner image.

More advantages of new CMOS image sensors include:

  • Higher frame rates and shutter speeds over CCD resulting in less image blur in fast moving objects.
  • Much lower cost of CMOS sensors translate into much lower cost cameras!
  • Improved global shutter efficiency.

CMOS image sensor manufacturers are also working to design sensors that easily replace CCD sensors making for an easy transition which results in lower cost and better performance.  Allied Vision has several new cameras replacing current CCD’s with more to come!  Below are a few popular cameras / image sensors that have been recently crossed over to CMOS image sensors

Sony ICX424 and Sony ICX445 (1/3″ sensor)  found in the Manta G-032 and Manta G-125 cameras are now replaced by the Sony IMX273 in the Manta G-158 camera keeping the same sensors size.  (Read more here)

Sony ICX424 (1/3″sensor), can also be replaced by the Sony IMX287 (1/2.9″ sensor) with pixel sizes of 6.9um closely matching the older IMX424 having 7.4um pixels.  Allied Vision Manta G-040 is a nice solution with all the benefits of the latest CMOS image sensor technology.  View the short videos below for the highlights.
