LED Lighting Vision System Peripheral Equipment CA-D Series
Back LightsFeaturing a variety of sizes and colors to fit any backlit application need.
Back light illumination techniques
Standard front lighting can cause inconsistent and low contrast of a target’s features due to shape, color and surface finish. Using a back light ensures transmission of the light through the target into the camera. If the target is opaque a silhouette is generated creating a strong contrast and outline for stable inspection. Even if a target is transparent it may have a range of densities to it (such as layered material or liquid in a bottle). Contrast can still be achieved through the changes in the absorption and transmission of light in the target.
New large model back light (7.8" × 11.73")
A large model size about the size of a sheet of paper has been added to the lineup.
Light is emitted right to the edge of the unit, which makes it possible to install it with the minimum space necessary in terms of the lighting area.
Connector pin strip
Shrink wrap defect detection
In this application example, the light is used as a specular light with a large lighting area.
