Outline
This device digitizes "spots and unevenness." Very weak differences in luminance can be detected with a sensitivity of 0.01%. Overall evaluation of "spots and unevenness," which are thin and difficult to discriminate and conventionally can only be discriminated visually, can be evaluated with this device. |

| Features |
 |
"Spots and unevenness" can be digitized according to the original spots and unevenness rate, which was conventionally impossible. |
|
"Spots and unevenness" according to weak luminance changes characteristic of FPD can be measured and identified immediately. |
|
In-house inspection specification can be unified as there is almost no drift according to the high degree of reproducibility of 0.01%. |
