Edmund Optics® Diffuse Reflectance Grid Distortion Targets Ideal for Front Illuminated Measuring
Edmund Optics (EO), 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.
