Features

Flexible combination – dual-channel plug-in system.

The Q8221 utilizes a dual-channel plug-in system. 

Various types of optical sensors and light sources are available as plug-in units.

Both channels can be used independently or simultaneously.

By using the desired combination of optical sensors and light sources,

the Q8221 can handle a wide variety of applications.

High measurement accuracy.

Ensure accuracy over the entire power and wavelength range.

The Q8221’s optical sensors ensure a high accuracy of ±2.5% at the calibration point

(short-wavelength sensors: Q82214 calibrated at 780nm;

long-wavelength sensors: Q82208. Q82215. and Q82216 calibrated at 1300nm;

Q82227 and Q82232 calibrated at 1550nm).

In the broadband wavelength region, they ensure ±4.5% accuracy by compensating

for the sensitivity curve at each sensor wavelength.

In the broadband wavelength region, they ensure ±4.5% accuracy by compensating the sensitivity curve at each sensor wavelength.

In addition, a linearity of ±0.5% is ensured.

Not only in the calibration point, but also in the broadband wavelength region and at the level to be measured.
