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.

Light emitted by silicon in solar cells peak at 1150nm

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)

Allied Vision’s high-resolution Prosilica GT now with 12, 16 and 25MP ON Semi PYTHON sensors

Allied Vision GT camera

Allied Vision Cameras

Allied Vision extends its Prosilica GT Large Format camera platform with three high-resolution ON Semi PYTHON image sensors (Python 12K, Python 16K & Python 25K)

Combined with robust thermal housing designed to operate in extended temperature ranges and fluctuating lighting conditions, the new Prosilica GT Large Format cameras are ideal for high-definition imaging applications with demanding requirements of robustness and design-in flexibility. They provide a great option for high-quality imaging for anyone looking to switch over from existing CCD cameras to CMOS cameras with similar resolutions and optical formats.

Features include:

  • Extended temperature range (-20 deg. C to + 50 deg. C)
  • NIR sensitivity up to 1100nm
  • Modular concept providing various lens mounts (M58, M42, and EF-mount)

Prosilica GT5120,  5120 x 5120, 25MP

Prosilica GT4096, 4096 x 4096, 16MP
This is a great replacement for the KAI-16000 CCD sensors!

Prosilica GT4090, 4096 x 3092, 12MP

Now that you have a great high resolution camera, what lens works best?Kowa F-mount lens

High resolution cameras with the ON Semi Python sensors are great, but only as good as the lenses you use!  It is imperative to have the sensor sizes matched with the lens formats.  Additionally, we need to make sure the lens resolution is adequate for the image sensor pixel size.

To aid in the lens selection, we have the following recommendation on lens series.  Recommendations as follows

Prosilica GT5120,  5120 x 5120, 25MP:  This camera has a  32.58mm diagonal image sensor, so a F-mount lens is required.  Two options are Kowa and Schneider
KOWA – F mount series
Schneider – F mount series

Prosilica GT4096, 4096 x 4096, 16MP:  This camera has a 26.06mm diagonal image sensor, also requiring a F-mount lens.
 KOWA – F mount series
Schneider – F mount series

Prosilica GT4090, 4096 x 3092, 12MP :  This camera has a 23.09mm diagonal image sensor which falls into a 4/3″ format.
KOWA 4/3″ lens series

As a note, as the pixel size is 4.5um, this is not as demanding on the lens resolution and will only require 111 line pairs/mm (lp/mm) making these adequate selections.

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..
