The benefits of using a camera with integrated zoom lens for global security systems

Posted by Gretchen Alper on Thu, Sep 12, 2013

When zooming in and out, it is critical that the object remain in the same position in the real time video, especially in outdoor imaging and mission critical global security applications.  For example, when observing one person in the crowd, you would want to be able to zoom in and out without losing track of the person. Full motion video cameras with integrated zoom optics ensure very accurate alignment of the sensor behind the lens to maintain the line of sight over the zoom range.

Sensor Cover Glass Removal: Machine vision camera customization for enhanced accuracy

Posted by Gretchen Alper on Tue, Nov 1, 2011

Standard image sensors found in industrial cameras come ‘of the shelf’ and can have limitations that can stand in the way of optimal performance, accuracy, and application-usefulness. As a result, it is often necessary to customize the sensors to meet specific system requirements.  Addressing certain aspects of sensors is a way how experienced camera manufacturers can customize cameras to meet the different needs of measurement methods.  In a previous blog we talked about our willingness to modify the anti-reflection coatings on sensors to improve performance at a desired wavelength.  Today we announce our full support of another modification option (cover glass removal) to eliminate limitations of the sensor design.

Machine Vision Lenses: What is the difference between f and F ?

Posted by Gretchen Alper on Mon, May 16, 2011

Often the f and F lens parameters are mixed up, but these are important parameters to select the right lens for your application. By choosing the lens with the right F can save you many expenses on lighting and or lens costs.

This nice explanation was provided on the machinevision4usersblog

Understanding machine vision lenses – focal length and f number

Few people charged with developing or maintaining a vision system are experts in photography, so the business of selecting a suitable lens can seem like a black art. Two of the areas of confusion are focal length and f number. Here’s what you need to know:
