This camera provides Versatility, Performance and a nice price. What is the JAI’s GO 5000 series?

JAI’s GO 5000 delivers an exceptional blend of high versatility, excellent performance, small size and best of all at a price of < $1K.  


The GO provides the perfect starting point for a wide range of machine vision applications.


The GO-5000 packs a high performance 5-megapixel CMOS imager (Anafocus Lince5M) into a compact form factor that fits in your fingertips. Using a combination of ROI and binning capabilities, this tiny camera can become almost anything you want – from a super-fast VGA camera (at nearly 450 fps) to a super sensitive camera using binning to create 10-micron, or even-20-micron effective pixel sizes.

High image quality
The GO-5000’s imager features a combination of analog and digital gain controls to reduce the amount of quantized noise in low-light images compared to conventional CMOS imagers offering digital gain functions alone. On the color models, an on-chip 4-channel analog gain function is utilized to allow individual adjustment of R, G, and B information for better white balancing with reduced noise.

Even at megapixel resolutions, the GO Series doesn’t resort to a rolling shutter or small pixels with low signal-to-noise ratios. 5-micron square pixels, global shutter, analog gain control, a built-in lookup table, and other advanced features help ensure image quality beyond entry-level expectations. 

Choose of image size and frame rate using Multiple ROI & binning options
Featuring multiple binning options and single or multiple ROI’s the GO-5000 can be easily configured to meet a wide range of customer requirements for resolution, speed, and optical formats.

For example, by creating a centered 1920 x 1080 ROI, users can configure the GO-5000 to provide high-speed 1080p HD video that fits completely within the optical format of a 2/3” C-mount lens. This is in contrast to CMOS cameras with 5.5 micron pixels which generate 1080p image sizes that are slightly larger than the standard 2/3” optical circle, thus requiring more expensive 1” image optics to ensure that vignetting will not occur.
Note: frame rates shown above are for GO-5000-USB and GO-5000-PGE, respectively.
Monochrome models feature a range of binning options including 2×2 and 4×4 binning to allow users to effectively create 10-micron, or even 20-micron, square pixels to maximize sensitivity and signal-to-noise characteristics for specific applications, as well as increasing the overall frame rates.

Choice of interfaces
Choose one of the advanced digital interfaces that best fits your needs. Options include powered interfaces (PoE) where a single-cable solution is desired, as well as both frame-grabber-based (PMCL) and “grabberless” configurations using GigE and USB3.0


Small size and weight
GO Series cameras measure 29 x 29 x 41.5 mm (excluding lens mount) and weigh less than 50 grams, enabling them to fit into small spaces or into vehicles or other applications where weight is critical.

The GO-5000 is one of the smallest 5-megapixel cameras available and weighs only 46 grams (lens not included)

Canon EF mount integrated into AVT’s GT1930L camera

Canon EF mount fully integrated 

The GT1930L EF is the first Allied Vision camera to receive an integrated Canon EF mount, allowing lens focus and iris to be adjusted through camera controls in the Vimba SDK or 3rd party software. No additional cabling is required, with lens drive power taken from camera power (PoE or Hirose powered). In the past, this has typically been accomplished via a third party mount adding more complexity to the overall solution.  

Stay tuned as this is the first integrated Canon EF mount..  but not the last!  Additional camera models will soon follow.  

Performance

The GT1930L EF is equipped with a Sony IMX174 Pregius™ global shutter CMOS sensor with a resolution of 1936 x 1216 pixels (2.35 MPixel) and frame rate of 50.7 fps (55.7 fps in burst mode) over Gige Vision interfaces. 

Extreme Conditions

The GT1930L EF is a great solution in applications where the GT’s impressive housing temperature range of -30 to +70 °C is an advantage, Canon EF lens control is needed, or a tight sensor to mount planarity tolerance is required.  Applications include outdoor imaging, traffic, high end security, MIL/Aerospace, machine vision and industrial inspection. 


Key Features include

  • Canon EF Lens control
  • Rugged Design for extreme environments
  • Power Over Ethernet (PoE)
  • Camera temperature monitoring

        Demystifying Lens performance specifications

        Machine vision lenses from various manufacturers may look similar, have identical focal lengths, but perform different… but why?

        The images above were taken with the same 5MP CCD GigE camera, identical iris and focus setting BUT with two different $250 class “Megapixel” C-mount lenses.  What lens would you choose?  

         

        The correct selection would be the lens that resolves the sensor pixel size and provides you with crisp images.  Too many times we have seen lenses paired incorrectly providing blurred images as seen on the right image even if they are classified as “Megapixel” lenses.  

        This can be avoided by understanding the lens performance in terms of the modulation transfer function also known as MTF which gives you the performance of light through a medium. It compares the intensity of the light before the optics vs. the intensity of the light after it goes through the optics. This is not a single number, but rather it varies as light hits the lens on or off axis, and is also dependent upon wavelength of the light. MTF is normally given in line pairs/mm or lp/mm vs. % transmission. Essentially, it tells you how well the lens can resolve a certain size spot. If you draw lines that get closer and closer together, at some point the optics system is going to see the 2 lines as a single blurred line. This is basically where the lens breaks down, and this is just past the limit of its resolving power.

        In the diagram below you can see as the lines get closer together the intensity fades. (picture courtesy of Schneider Optics)

        Note: Some lens manufacturers give MTF as only lp/mm and not vs. % transmission. E.g 60
        lp/mm. This does not mean that you cannot see objects smaller than this MTF, it is just that the intensity of the image is lower than 100% at this rating. As the intensity drops at some point your eye or the processing SW can not distinguish between line pairs.



        Ideally, the total MTF is derived from a multiplying all the MTFs of the system. This would include the MTF of the lens, the filter, the camera, the electronics, etc.

        So if you have a megapixel sensor with a high MTF, but put a low cost lens in front, you have degraded the MTF of the system.  Garbage in, garbage out!  


        The bottom line is to know the pixel size of the given sensor in which you can then derive the lens resolving power in terms of lp/mm.  In some cases, curves are available to plot lp/mm versus contrast providing the MTF of the lens.   You are now in a position to select a lens matched to your sensor!
