Discover the future of imaging precision with PureTech's Imaging Calculator. Expertly designed to ensure your target stands out in perfect detail, our state-of-the-art tool is a game-changer for both visible and thermal imaging. Simply input key parameters shown below and watch as the calculator tailors every pixel to perfection.


  • Width & height of image sensor,

  • Number of lateral & vertical camera pixels,

  • Horizontal Field of View (HFOV) of the camera or alternatively the focal length of its optics,

  • Camera installation height,

  • Parameters through which the target of interest and tallest expected target is specified namely the heights and widths of encompassing bounding boxes and the ranges from the camera to the targets (of interest and tallest).

  • Corresponding focal length to the input HFOV or vice-versa when the input is focal length,

  • Vertical field-of-view (VFOV),

  • Angle subtending the blind zone, and

  • Several more.


Keep in mind that when you're setting the target range in the calculator, it assumes the land is flat. This helps in estimating how far you can see, which is also known as the 'optical horizon'.
