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.
Edmund Optics (EO) has expanded its line of Techspec imaging and machine-vision lenses.
Edmund Optics (EO) will exhibit its Techspec compact telecentric lenses at the Vision Show in Stuttgart, Germany.
Edmund Optics has introduced the GigE CMOS machine vision cameras, featuring an adjustable frame rate via binning, sub-sampling or AOI.
Edmund Optics (EO) has released Techspec compact fixed focal length lenses, designed for use in machine vision applications.
Corona cameras are used as NDT (non-destructive) equipment as a means to find electrical abnormalities and faults. Corona is a partial electrical discharge created on conducting surfaces where a local high e-field exceeds a certain critical value. In most cases corona is referred to as a deficiency that should be eliminated, in particular so if the surface is made of polymeric material.
