Application Examples

Various uses depending on the application

Bright field

Visual inspection of rectangular workpieces
Visual inspection of satin metal
Various foreign contamination, presence inspection, etc.
Example Configuration

Example

Diffused lighting is illuminated from an angle, and the specular reflection light is observed. Light emitting surface width can be selected to match the workpiece and characteristics.

Diffusion Plates

DF-LB

Light characteristics can be changed by changing the diffusion plate.
The DF-LB Series diffusion plates have lower uniformity and higher transmissivity than the standard type diffusion plates installed at the time of shipment.


*For high power type lighting, DF-LB Series diffusion plates are installed at the time of shipment.

Diffusion Plates Series page

Polarizing Plates

PL-LB

These are used together with a polarizing filter attached to the camera lens to eliminate surface glare.
