Learn about the new 5GigE camera interface

Dalsa Nano 5GigE

Machine vision interfaces have continued to evolve over the years increasing data throughput and cable lengths.  Commonly used interfaces are GigE and USB3.  However, 5GigE is an interface now gaining attention in the industrial imaging / machine vision market with some nice advantages.

We will outline the benefits of 5GigE, but first, lets give a brief overview of the commonly used camera interfaces, with their pluses and minuses:

GigE  / GigE Vision

  • 110 MB/s of sustainable throughput.  In real world terms, a HD, 2MP camera can get 50-55 fps in 8 bit mono or 8 bit color mode.  Note, this isn’t real HD, since you need 60 FPS.
  • Data cable lengths up to 100m using regular CAT 5e/6 cable.
  • Easy to put multiple cameras on a system.

USB 3 / USB3 Vision

  • 420 MB/s of data throughput.    A HD 2MP camera can run 60 fps in 8 bit mono or color and can  also run RGB at 60 FPS no problem.  With the higher throughput,  a 5MP camera can achieve 85 fps in 8 bit mode.
  • Data cables up to 5 meters and up to 20 meters with active cables. However, active cables can be quite costly, adding up to $200 in cost.
  • Not as easy as GigE to put multiple cameras on a system, and gets harder with each additional camera, especially if you have limited USB3 controllers.

As a note, there is no cost difference when using cameras with the same sensor from the same manufacturer with USB or GigE!  They will cost about the same with no premium for one interface over the other.

gige nano 5gigeWhat are the limitations of GigE and USB3 now solved by 5GigE?

  • USB3 is limited in cable length, so going faster than GigE is great, but you can not have long cable lengths.
  • GigE has cable lengths up to 100 meters, but is limited to ~ 110MB/s of data, so you do not have the high frame rates as in a USB3 camera.
  • USB3 in 4+ camera systems is not as stable as GigE AND you’re still limited on cable lengths.

Wait! – What about 10GigE? 

Up until now, 10G was the next interface. However, the jump to 10G has quite a few limitations as outlined below.

  • Heat generation is significant, so cameras are large and not in the smaller 29 x 29mm cube form factor.
  • Not a lot of demand for very high speed 10G, so not a lot of sensors being offered
  • Minimal number of manufacturers for 10G, higher cost.
  • Special cabling, either optical or high quality cat 7.

What we have found is that there are several types of applications for 10G cameras and are as follows

  • Applications where you need 10G of speed of course (high resolution + fast frame rates)
  • Require greater than  110MB/s of data and need long cable lengths.
  • Where there is the required combination of 110MB/s for high frame rates, multiple cameras and long cable lengths, 10G is a perfect solution.

We have seen that the need for higher bandwidth + long cable lengths is more prominent vs. the real need for 10GigE!

 Introducing 5GigE that provides increased bandwidth, long cable lengths at reasonable prices! or N Base T.5GigE machine vision applications

5GigE (also known as N Base T) has become a new standard for industrial, machine vision cameras.

In the general compute world, a much much larger market than vision, there has also been a need to go faster than GigE. However, the issue of replacing the existing cabling is the major issue preventing this. If you think of a big box store, say a Home Depot for instance, the amount of cabling is huge. Ripping that out and rewiring far exceeds the cost of the equipment to use it!

5G was made to go faster, but use existing cabling. Regular cat6e cable can be used, and 5G is a subset of 10G, so all switches etc. can be kept in service.

5G gives users in the vision market USB3 speeds, but with ALL of the regular GigE features, at a very small premium!

Get a 5MP lens for the price of a 3MP one! FUJI’s new XA-5M lenses.

FUJI LensesFujinon introduced their first 5MP series, the  5MP SA-1s  over a decade ago. Back then they were the first really high quality lenses for under $500.

Now, they have introduced their next generation 5MP series,  the new XA-5M ,  and they have made them smaller, better, and less expensive!  Now you can get a 5MP rated lens for very close to what 2 or 3MP lens cost with the new HF-XA-5M series lenses!  1stVision has preferred pricing and stock!   Contact us for a quote

The Fujinon XA-5M are designed to work at 3.45um resolution (and very good at 2.5um), so they are a great choice for the 3.45um pixels found in the Sony Pregius IMX line of sensors.  See image below showing a heat map of the resolution.(Darker red is higher resolution, 2.7um, orange is 3.3, yellow is 4um, light blue is 5um, and dark blue is 6um)

FUJI resoltion chart

Further, the new CMOS sensors have more of a ‘stacked’ architecture, meaning each pixel is tall.  Without having a lens that has a small chief ray angle, which keeps the light rays as close to perpendicular as possible to the sensor, each pixel possibly shades its neighbor.  The new Fujinon lenses are designed to solve that problem for these sensors.  So when comparing this line to their competitors, there is less shading at the edges and more even illumination!

The results can be seen when comparing the center to edges in an application.  In the example below, the text in the center and edge on the FUJI “4D High Resolution” lenses is crisp vs the competition on the right.

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 - light emmission at 1150nm
Light emitted by silicon in solar cells peak at 1150nm

Learn more about applications solved with SWIR cameras HERE. 

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.

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.
