Flat light (TH2 Series)
A dent in the workpiece cannot be visualized.
Allows for imaging of unevenness and striae in transparent objects that are difficult to visualize
Imaging Solution for Transparent Objects Through Screen Projection
Provides more highly directional illumination than conventional lights, enabling the clear observation of surface irregularities and flow lines in transparent materials that are difficult to visualize with standard lights.
Application Example
- Observation of Flow Lines in Glass and CD Cases
- Film surface irregularity inspection
PFBR-150 Series + Low Magnification Telecentric Lens
custom-order
- Achieves highly directional illumination with the PFBR-150 Series and a low magnification telecentric lens.
- Enables imaging of irregularities and striae in transparent objects that are difficult to visualize.
- Allows image acquisition utilizing differences in refractive index between materials.

Equipment Used
PFBR-150 Series
High-output LED light source surpassing 250 W metal halide light source is used as the backlight. A lens can be installed by mounting a dedicated adapter.
Low-magnification telecentric lens
Highly directional illumination is achieved by combining with the PFBR-150 Series.
