Product Family Description

  • Diffuse Reflectance Treatment Mimics Ceramic Targets
  • Chrome Pattern on Substrate
  • No Glare with On or Off Axis Lighting
  • Perfect for Front Illuminated Measuring

Diffuse Reflectance Grid Distortion Targets have been treated to create a surface that diffusely reflects light back, avoiding glare across the image surface. Using these targets, one can easily determine the precise amount of distortion present in an image. The dot center can be calculated using blob analysis in measurement software and calculated against the standard to remove distortion from the image. Diffuse Reflectance Grid Distortion Targets can be used with a wide variety of lenses, from wide-angle to telephoto. The targets are offered in 2 substrate sizes and 3 dot frequencies.
