High-precision measurement
Near infrared rays, almost impervious to ambient light or the effect of different colors, are pulse emitted through a lens as parallel light and strike the measuring surface. The light reflected from the sample surface converges in the detector which has a slit in the front so that only the light reflected from the direction of the sample surface is received.
Detector output is band-amplified by a pre-amplifier, rectified, and converted into degree of gloss value for display as gloss value. The IG-320 offers stable and high precision measurement with ±0.5% full scale reproducibility. |
