New High Resolution 1.1” Lenses are a perfect fit for the new Sony 1.1” 12 MP Sensor cameras

Sony’s Pregius image sensor line has continued to expand to higher resolutions and sizes.

The latest 12 megapixel, Pregius IMX304 sensor has a 3.45um pixel pitch which requires a 1.1″ lens to prevent vignetting.

 In order to obtain optimal contrast within an image using this sensor,  a lens supporting at least 145 line pairs / mm must be used.

 


The lenses are optimized for down to 3.1um pixel pitch images.  Use of state of the art optical technology enables high contrast and high resolution from the center to edges of the lens, despite the large lens aperture.   

Examples below






The image to the left demonstrates improper pairing of a lens without enough performance to adequately resolve the size of the pixels on the camera.  Zooming into the given areas shows lack of contrast

 

 

The image to the right demonstrates the performance of the Tamron 1.1″ lens on the new 12MP, 3.45um pixel pitch image sensors.  Zooming into the given areas show high contrast in the center and edges of the lens.




Alternative solutions prior to now would be to use a 4/3″ or F-mount lens which are very expensive.  If a 1″ format was used, you will have vignetting on 5% of the edges of the lens. This lens is the best solution for the larger 1.1″ sensors!

Key Features include

  • Compatible up to 1.1″ C-mount cameras:  Compatible with image sensors up to 1.1″ formats and image circle diameters of 17.4mm (effective image circle diameter to 17.6mm).  
  • Industrial leading high contrast and resolution:  Compatible with 3.1um pixel pitch image sensors, up to 1.1″ sensors.  Perfect for Sony Pregius IMX304, 12 megapixel sensors.
  • Lens designed for High-Fidelity imaging:  Uniform high contrast and resolution from the corners to the center despite the large aperture size.  Provides 160 lp/mm in the centers.  
  • Combination of advanced coating technology:  Integration of advanced techniques such as broad band anti-reflection coatings are used, additionally allowing for high image quality at close distances. 
  • Enhanced Functionality and Utility:  Well tuned rotation torque of both focus and iris control rings facilities smooth adjustments.  Lock mechanisms on the rings can be positioned at a choice of tree lock positions.

White Paper – Learn about High Dynamic Range (HDR) Imaging techniques for Machine Vision

What is High Dynamic Range (HDR) Imaging for machine vision?

First we need to understand what is dynamic range in an image! 

Dynamic range is a term used to describe the difference between the brightest part of a scene and the darkest part of a scene at a given moment in time – essentially the amount of contrast within a single image.  

The four images above provide an example of a high dynamic range scene.  Note how there are details in each exposure that may not be visible in a different exposure (Note that we can see the buildings in the lower right image vs the upper left image). None of the exposures can capture the entire scene without under-saturing (turning dark) or over-saturating (turning white)

In many imaging applications it becomes difficult to discern the dark and bright areas due to lack of dynamic range within the camera.  In turn, cameras using HDR methods must be utilized in order to obtain a high dynamic range image.  

This white paper provides a technical background explaining HDR imaging.   You will learn about various methods used to achieve HDR images including  sequential image fusion, multi-slope pixel integration and dual-sensor image fusion.  Industrial cameras from JAI are identified that support these various methods.  
 
By utilizing the best HDR methods and camera solutions, a HDR image can be achieved and provide detail in the bright and dark areas of an image.  (HDR image below)

Teledyne Dalsa Nano XL-M4090 cameras – 16MP cameras are now faster, cheaper and smaller!

The Genie Nano XL-M4090 offers the On-Semi Python 16K monochrome sensor with a resolution of 4096 x 4096.  Nano XL-M4090 offers Teledyne Dalsa’s “Burst Acquisition” and “Turbo Drive” features allow for capturing images at 30 fps in 16 Megapixel resolution while maintaining good image quality.  

The new Nano XL camera provides 16 MP at a fraction of the cost of older KAI-16000 image sensors with improved performance, faster frame rates, and smaller image format!

Contact us for pricing!
The new cameras are fully GigE Vision compliant with higher frame rates achievable with partial scan modes and packed with beneficial features

Features and Benefits at a glance

  • Resolution – 4096 x 4096 with 4.5um pixels
  • Speed – Using the latest global shutter CMOS technology, the new 16MP XL more than doubles the frame rate of previous 16MP CCD cameras using the KAI-16000 sensor.  Utilizing Turbodrive, and 500 MB of on-board memory; frame rates of 30 fps can be reached  (Read more about TurboDrive )
  • Cost per Pixel is dramatically reduced!  – Pricing starting below $4300 provides a substantial savings for the same resolution vs older 16 MP CCD models.  
  • Lens mount options / Pixel Pitch – On-Semi uses 4.5um pixels providing a APS-H optical format (32.6mm diagonal) while still maintaining good performance and low noise.  The XL has a M42 mount and will have a M42 to F-mount adapter available. 
  • On-board memory – 500 MB
  • Wide Temperature range – 20 deg. C to + 60 C

Applications include:

  • Machine Vision inspection
  • Intelligent Traffic Systems (ITS) 
  • Large scale metrology
  • Pick and Place machines
  • Motion monitoring
  • Aerial Surveillance






 On-Semi has continued to expand the image sensor line and in turn, it is available from various camera manufacturers and interfaces.  

If you do not need 16MP, the Dalsa Nano product line has become very extensive with resolutions from VGA to 25MP.  Click here NOW to see the complete portfolio
