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

Similar to ceramic targets, the Diffuse Reflectance Grid Distortion Targets have been treated to create a surface which 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. Offered in 2 substrate sizes and 3 dot frequencies, the targets can be used with a wide variety of lenses from wide angle to telephoto.
