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.

Plastic sheet
LNSD-300SW(A)

Imaging example of plastic card using LNSD-300SW(A)

For highly deflective workpieces, brightness is not uniform.

LB-300X50SW

Imaging example of plastic sheet using LB-300X50SW

Wide light-emitting surface reduces the effect of deflection for uniform brightness throughout the entire image.

Backlight

Cylindrical container liquid level inspection
Foreign contamination inspection on sheet
Film scratch inspection, etc.
Example Configuration

Example

Diffused lighting is illuminated from the back of the workpiece. Suitable for translucent container foreign contamination inspection, liquid level inspection, silhouette inspection, etc.

Transparent container stain inspection

LB-300X150SW

LB-300X150SW

Uniform diffused lighting illumination from a wide light emitting surface minimizes the effect of unevenness and clearly images stains.

Dirt on fiber workpieces
Workpiece

Workpiece: Tracing paper

Tracing paper
LNSD-300SW(A)

Imaging example of tracing paper using LNSD-300SW(A)

The light-emitting surface is narrow and the angle of light to the surface is small, reducing the overall light hitting the paper and making it difficult to see the dirt.

LB-300X150BL

Imaging example of tracing paper using LB-300X150B

The large light-emitting surface allows light to hit the paper from multiple directions, making it easier to see the difference between stains and paper.

Diffused dome illumination

Visual inspection of electronic components
Stain inspection of non-woven fabrics, etc.
Example Configuration

Example

Uniform diffused lighting is illuminated from 2 directions to reproduce the dome effect. Images can be captured with minimal shading and halation effects on uneven surfaces.

Scratch inspection of uneven mats
Workpiece

Workpiece : Joint mat

Joint mat
LB-300X150SW×2 units

LB-300X150SW×2 units

Clear imaging of scratches by suppressing shadows on uneven surfaces.

Diffused dome illumination

Wide-range uniform illumination

Sealant coating inspection
Print inspection on satin metal
Lighting for robot picking, etc.
Example Configuration

Example

Uniform diffused lighting is illuminated on the same axis as the camera. Also effective for wide-area imaging, such as wide workpieces, etc.

Foreign contamination inspection of non-woven fabrics
Workpiece

Workpiece : Mask

Mask
LB-300X150SW×2 units

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.
