Time course measurement of residual brightness


*Irradiation conditions:D65 light source, 1000 lx 30 minutes
Indications of brightness
*Since there are individual difference in perception, these indications should be used as reference only.

5mcd/u or more : Theobject is visible, bright, and clear.
3mcd/u : Contours of the object are visible.
2mcd/u : The object is berely visible, faint, and unclear.
0.3mcd/u : The object is almost invisible.


Residual brightness 7.6mcd/u after 60 minutes
*These values are measured values but not standard values
(The values may vary with the composition of materials, such as density and weight per unit.)

*Irradiation conditions:D65 light source, 200 lx 20 minutes


Residual brightness 0.3mcd/u after 712 minutes
*These values are measured values but not standard values
(The values may vary with the composition of materials, such as density and weight per unit.)
