You can't improve what you can't measure...

That's why we keep adding more measurement methods. At Y Systems, we strive to be at the cutting edge of both reproducibility and sensitivity of material property measurements. Whether for in-situ observation, external measurement, or for research, we offer fully automatic measuring equipment for production.

Phosphor Material Characterization

Conventional white LEDs are fabricated from a combination of blue emitting diodes and yellow phosphorescent material.
Some of the blue light is absorbed to make yellow light, and some is transmitted.
A precise ration of blue and yellow is required to make a specific white.

YWafer-YB (yellow and blue) was built on the fundamental design of the YWafer-GS transmission measurement mapping where the broad
band transmission source was replaced with a standard blue LED typically used to make the above type of white light emitting diodes.
