Visible, IR, UV, Multispectral and now SWIR. Metaphase continues to lead the machine vision LED illumination market with innovative products that utilize the latest in LED technology. SWIR, typically defined to be wavelengths included in the 900nm to 2500nm range, is another tool that can be used to find defects in objects where typical UV, Visible and IR illumination do not provide the necessary contrast. Like visible light, different materials will absorb and reflect SWIR. Applications include inspection of fruit (bruising), solar cell & semiconductor wafer inspection, anti-counterfeiting, leak detection, presence of coatings, fill level, moisture presence, and more.
