It has become possible to visualize defects and impurities in mirror-surface materials that are difficult to inspect using normal LED lighting.
PHASERAY's "shadowless lamp" and "light interference" technologies make inspection possible from any angle,
and also reveal defects and impurities that were previously invisible.
Features
This is an inspection lighting device specialized for detecting defects (scratches, holes, fingerprints, chips, cracks, etc.) and impurities (particles, contaminants, dust, etc.) on mirror-surface materials. By applying eye-friendly shadowless lamp technology for medical lighting, you can work from any angle without having to assume an awkward posture. In addition, PHASERAY’s optical interference technology makes it possible to highlight only defects and impurities.
Freeing yourself from the hassle of figuring out the lighting position with LED lighting will change the world of visual inspection equipment/process design.
Example of use in semiconductor wafer inspection
Good posture
Illuminates a wide area
Reducing work time = Reduced utility costs
A wide area (up to φ400) is illuminated, so there is no need to move the lighting equipment to suit the size of the object.
Improved quality and Reduced complaints
A heat sink mechanism is used for the cooling system, so there is no risk of contamination inside the clean room due to the cooling fan.
Shorter work hours, Reduced labor costs, Cope with an aging workforce
With a normal light source, when only part of the body is illuminated, the observer must change position while observing, which can lead to fatigue during long examinations. However, our lighting allows the observer to observe while maintaining the correct posture, reducing fatigue.
If the illumination range is insufficient, observation techniques are required, but if the entire surface is illuminated, no skill is required and anyone can observe in the same way.
