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)
  • Fixed Pattern noise correction,  Defect Pixel Correction, and Trigger over Ethernet.

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.

Sony has a great new 1.1” Image Sensor, but what kind of lens can I use with this format? Computar MPY Series!

Computar MPY lens series

If you have been around industrial camera lenses for a while, you know that there are many ½” and 2/3” lenses, not as many 1” lenses, but what do you do when you have a 1.1” sensor?!   The solution?  Use the Computar MPY  12 Megapixel lenses!Contact us

If you have been following Sony’s new IMX image sensor product line, their newest sensors are based on a 3.65um pixel pitch.  However, when you scale this up to their new 12MP sensor (Sony Pregius IMX253, IMX304), the sensor size becomes 1.1” (17.6mm diagonal) format.  A 1” lens format will not cover this image circle and in turn has vignetting in your image  (Read our blog post on sensor size vs. lens size ) .

One possible solution is to use a 1” lens and vignette 5% on each side, or use a 1” lens and stop it down where the vignetting goes away.  However this is not an optimal solution.  A second solution is to use a F Mount lens, but if the camera is a C mount, you will need a C to F adapter, again less than ideal.

Fortunately there are some C mount lenses that are greater than a 1” image format.  Kowa and Schneider both have been shipping 4/3” format lenses, although these are quite expensive.  Recently, Computar has come out with a line of 1.1” format lenses SPECIFICALLY  for this sensor!

Learn about 1stVision’s new OEM 1” machine vision lenses which provide excellent price vs performance ratios

1" optical format machine vision lensesFor many years 1stVision has offered several lines of OEM machine vision lenses. These lenses are ‘unbranded’ but they are made with the glass of one of the big three Japanese optical manufacturers.

1st Vision lenses have excellent optical performance for a great price currently offering a product line designed for a 2/3” image formats with 2MP and 3MP resolutions.

The OEM machine vision lenses offer some distinct advantages:

  1. They are less expensive than similarly performing ‘branded’ lenses
  2. When designed into instruments for resale, all issues come back to the original manufacturer.  The end user cannot bypass the manufacturer, ensuring you, when your users have problems, you know about them!
  3. With a good price point, the 1″ format can be used for all smaller sensor sizes using the “sweet spot” of the lens!

Learn how the new IDS Imaging GigE Vision IP65/67 cameras can save you money

IDS Imaging Factory Automation (IP65/67) cameras have been released with key features to help save money on industrial installations.


The new versions are “plug & play” with 3rd party GigE Vision software such as Cognex Vision Pro & National Instruments Vision software.  

The IDS Imaging GigE uEye FA (Factory Automation) industrial cameras are specifically designed for harsh environments, providing IP65/67 protection using a GigE interface.  

Using a water tight lens barrel and M12 connector eliminates the need for costly IP65/67 enclosures, saving space and additional assembly costs.  Attractively priced, the FA cameras are an excellent camera for harsh environments versus standard cameras with enclosures.

Key Features are as follows:

  • IP65 / IP67 Protection – Eliminates the need for an additional costly enclosure, protecting against dirt, dust and water splashing.  
  • GigE Vision compliant models – “GV” models available for use with GigE Vision compliant 3rd party vision software or use with the robust IDS Imaging Cockpit software and SDK using the “UI” models
  • Compact size with IP65/67 protection – Measuring 41mm x 52mm x 43mm long, the camera design provides less volume than using additional enclosures with non IP rated cameras
  • 8-Pin IP Rated connectors – Used for GPIO, trigger and flash within harsh environments. 
  • GigE PoE Interface – Using Power over Ethernet (PoE), one cable can be utilized for data and power saving money on installations.
  • Resolutions from 2.3 to 5MP using the Popular Sony Pregius CMOS image sensors (IMX249, IMX265), IMX264) in Mono and Color models

IDS uEye cameras configured for IDS Imaging Software & SDK, provide you with an extensive development platform supporting Windows, Linux and embedded platforms.  (Learn more about the IDS Imaging software here,.. which is free! )
