Overview
Inter Action makes light sources for testing CMOS image sensors. During test, each sensor is illuminated with uniform light of known intensity and spectrum to check sensitivity and find pixel defects.
It designs the light sources and the systems around them, and also supplies optical units and environmental test equipment for semiconductor equipment.
Business: Light sources for CMOS image sensor testing
Why it matters
- In image sensor test the light source acts as the reference standard, so its uniformity limits how precisely pixels can be graded.
- Japan is a major producer of image sensors, which gives sensor test suppliers a large home market.
