An Illuminating Look at the Critical Role of Lighting
in Successful Vision Sensing.
No matter how powerful or robust a sensor is, successfully
meeting challenging vision applications relies heavily on matching
the vision sensor with appropriate lighting. Lighting sources,
geometry and techniques need to be optimized to the target’s
optical properties. While contrast is critical, target size, speed,
working distance, topography, color, and likelihood of defects are
among the other considerations.
The choices in lighting optics, color lters, diusers and
focusing elements are as varied as the choices of light sources,
which include LEDs, uorescents, lasers, and incandescent
halogens or xenons. Lighting is essential to any successful vision
sensing system.
Fortunately, Banner oers one of the industry’s most
extensive selection of lighting solutions for vision sensing, plus
the knowledge, personnel and experience to create an integrated
solution that delivers reliable performance at desired speeds.
Banner’s lighting selection and accessories provide single-source
convenience and support for matching a sensor and illumination.
For the most challenging applications, Banner engineers will work
with your sample parts to design an integrated optimal solution.
Ring Light (see page 32)
Mounts directly to the sensor for easy
setup and illuminates any object
directly in front of the sensor
Backlight (see page 33)
Installs behind the target, directly
facing the sensor; has a highly
diused surface and uniform
brightness, with a lower intensity
than other lights
Area Light
(see page 34)
Provides even illumination in a
concentrated area
Spot Light
(see page 35)
Provides even illumination in a small
concentrated spot
Linear Array Light
(see page 35)
Provides high-intensity illumination
of large areas, at long distances
Tubular Fluorescent Light
(see page 35)
Features icker-free high-intensity
illumination of large areas
On-Axis Light
(see page 36)
Provides collimated illumination in
same optical path as camera
Highly Diused Light
(see page 36)
Softly illuminates from multiple
directions, minimizing glare
and shadows
Low-Angle Ring Light
(see page 37)
Illuminates nearly perpendicular to the
direction of an inspection, enhancing
the contrast of surface features
Multi-Light (see page 37)
Has independently adjustable light
intensity on each axis
Structured Light
(see page 37)
Uses laser emitter with extra bright
light for 3-dimensional sensing
