Applications

ImageMaster® HR TempControl

In addition to determination of the MTF, the key measurement parameter is the change in both the flange focal length and effective focal length when the temperature changes.

In addition to military and aerospace applications, cameras are also being used in the automotive industry as safety-critical systems whose properties must be tested and ensured across a broad temperature span.

In general, the image quality of lenses can be affected by temperature influences on the optical components and mounting materials. Crucial lens parameters such as effective focal length and flange focal length can be temperature-dependent and have an impact on the camera’s focusing function.

Due to the easy system conversion from VIS to IR, the specific requirements from various areas, including the automotive industry, development of mobile phone lenses, and the military and aerospace sectors are covered.

  • Effective Focal Length (EFL)

  • Object angle vs Image height

  • EFL vs Image height

  • Distortion

  • MTF vs Frequency

  • MTF vs Field
  • MTF vs Focus
  • MTF vs Focus vs Field
  • Field Curvature
  • Depth of Focus
  • Chief Ray Angle
  • Flange Focal Length (FFL)
