N E RL IT E ® DOAL ®
Diffuse On-Axis
Lighting (DOAL)
Available In Three
Colors & Infrared
Microscan’s wide range of NERLITE products
can illuminate any part or mark for successful
machine vision and auto ID applications.
Available In
Four Sizes
DOAL illuminators provide the best contrast for
images of features marked or embossed on a flat
specular surface with diffuse and uniform on-axis
illumination. With the coaxial lighting approach,
specular surfaces perpendicular to the camera
appear bright, while surfaces surfaces which are
marked or embossed absorb light and appear dark.
DOAL: At a Glance
• Provides superior uniformity throughout the
illumination envelope
• Improves the accuracy and repeatability of machine
vision performance on specular surfaces
• Compact, lightweight package can be used on moving
camera modules
• Reliable, solid state LED illumination
• Passively cooled models are available (DOAL 25
& DOAL 50)
Illumination Example:
Object
Resulting Image
Application Examples
•Evenly illuminate flat, shiny surfaces
•Enhance scribed, indented, or embossed features
•Create contrast between specular, diffuse, or absorptive surfaces
•Diminish visibility of clear overcoats or coverings
•Electronic component inspection
•Fiducial location
Stamped characters on a metal plate: High contrast image allows
inspection or reading.
