Description

DOAL Illuminators OVERVIEW: DOAL (Diffuse On-Axis Light) illuminators provide diffuse, uniform illumination for flat specular surfaces. With the coaxial lighting approach, specular surfaces perpendicular to the camera appear bright, while surfaces which are marked or embossed absorb light and appear dark. By providing greater uniformity than conventional sources, DOAL’s increase machine vision accuracy and repeatability. Available in 3 colors and Infrared 4 sizes are available Provides superior uniformity throughout the illumination envelope Compact, light weight package can be used on moving camera modules Passively cooled models are available (DOAL *5 & DOAL *0) APPLICATIONS: Evenly illuminate flat, shiny surfaces Enhance scribed, indented, or embossed features Create contrast between specular, diffuse and/or absorptive surfaces Diminish visibility of clear overcoats or coverings Electronic component inspection Fiducial location
