Diffuse Reflectance Grid Distortion Targets
Edmund Optics (EO) has introduced its Diffuse Reflectance Grid Distortion Targets, designed to have similar performance to ceramic targets.
The Diffuse Reflectance Grid Distortion Targets have been specifically treated to create a surface that diffusely reflects light back, allowing the user to avoid glare across the image surface.
The targets feature a chrome pattern on the substrate and produce no glare, with either on- or off-axis lighting sources.
Diffuse Reflectance Grid Distortion Targets allow the user to determine the exact amount of distortion present in an image.
To remove distortion from the image, the dot centre can be calculated using blob analysis in measurement software and then calculated against the standard.
Suitable for front illuminated measuring applications, the targets can be used with a wide variety of lenses, ranging from wide angle to telephoto.
Diffuse Reflectance Grid Distortion Targets are available in a 2in x 2in configuration with dot sizes of 0.0625mm, 0.15mm or 0.25mm.
The 3in x 3in targets are available in dot sizes of 0.125mm, 0.25mm and 0.5mm.
