Optical Characteristics
Figure 12:
Optical Characteristics of AS7263 (Pass Band)
(1)
Note(s):
1. Calibration & measurements are made using diffused light.
2. Each channel is tested with GAIN = 16x, Integration Time (INT_T) = 166ms and VDD = VDD1 = VDD2 = 3.3V, T
AMB
=25°C.
3. The accuracy of the channel counts/W/cm
2
is ±12%.
4. The light source is an incandescent light with an irradiance of ~1500W/cm
2
(300-1000nm). The energy at each channel (R, S, T, U,
V, W) is calculated with a ±33nm bandwidth around the center wavelengths (610, 680, 730, 760, 810, 860nm).
