Edmund Optics® Diffuse Reflectance Grid Distortion Targets Ideal for Front Illuminated Measuring
January 29, 2009, Barrington, NJ. - Edmund Optics® (EO), the preferred supplier of optical components, introduces their 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 troublesome 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.
Targets easily determine amount of distortion
Diffuse Reflectance Grid Distortion Targets allow the user to quickly and easily determine the exact amount of distortion present in an image. To remove distortion from the image, the dot center can be calculated using blob analysis in measurement software, such as NI Vision Builder software, sold by Edmund Optics (stock number 56-807), and then calculated against the standard. Perfect for front illuminated measuring applications, the targets are ideally suited for use with a wide variety of lenses, ranging from wide angle to telephoto. "These Diffuse Reflectance Grid Distortion Targets are ideal tools, allowing our customers to calculate distortion so that they can perform undistorted wide angle imaging as well as test distortion on their own optical systems," added Nicholas James, Product Line Engineer, Edmund Optics.
Available in two substrate sizes and three dot frequencies
Edmund Optics' Diffuse Reflectance Grid Distortion Targets are available in two substrate sizes and three dot frequencies. Diffuse Reflectance Grid Distortion Targets are available in a 2" x 2" configuration with dot sizes of 0.0625 mm, 0.15 mm or 0.25 mm. The 3" x 3" targets are available in dot sizes of 0.125 mm, 0.25 mm and 0.5 mm. EO's Diffuse Reflectance Grid Distortion Targets are in-stock and available for immediate delivery.
