  1. Math, Magic And MTF: A Cheat Sheet For The Vision System Community
    4/19/2017

    MTF is the best proxy for lens performance, but the math behind it and the graphs that depict it often obstruct understanding. This paper demystifies MTF, arming vision system decision makers with the knowledge they need about it to choose the right lens every time.

  2. The Seductive Siren Call Of The “Megapixel Lens” (And Why You Shouldn’t Listen To It)
    11/11/2016

    In response to the popularity of megapixel cameras and sensors, many lens manufacturers are marketing "megapixel lenses." The problem? There's no such thing.

  3. Specifying Lenses For Megapixel Cameras
    8/24/2016

    Continuing advances in high-resolution sensors with higher pixel densities and smaller pixels are challenging optics manu­facturers to produce lenses of increased per­formance. To understand how lenses can affect the performance of imaging systems, it is necessary to grasp the physics behind diffraction, lens aperture, focal length, and the wavelength of light (see “Match­ing Lenses and Sensors,” Vision Systems Design, March 2009). Additionally, other design limitations also restrict the optical capabilities of a lens, even before manufac­turing tolerances are taken into account.

  4. Do You Know What You Are Really Buying?

  8. Saving The Lens For Last?
    1/6/2016

    Designers have been known to “save the lens for last” when creating vision systems with very specific black box dimensions and lighting, resolution, and pixel specifications. One solution to this dilemma is a new and improved design approach called concurrent engineering.
