4 kinds of photodetectors are suitable for various requirements.
When using W as the unit, the measurement resolution is 0.005 to 0.1%; when using dB as the unit, it is 0.01dB.
The measurable wavelength is 0.38-1.8μm (the measuring range of the instrument, the actual measuring range must be determined according to the indicator of the photodetector); the sensitivity is 60dB at 1.3μm and 1.55μm.
The photodetector has built-in wavelength reactivity, so by specifying the compensation wavelength, the absolute optical power can be easily and directly read out.
A simple change in the connection makes the uncompensated measurement also very accurate.
TQ8210 has the function of auto-monitoring of the light detector, and displays the model of the instrument and the model of the light detector when it is turned on.
The dynamic range of the measurement is -60dBm--+17dBm
The display mode is two lines, the previous line is 4 digits of the measured light wavelength, the next line is the optical power 4 1/2, the unit is W or dB
The light detector with random band is Q82017A (.4 to 1.1 nm, -60 to +17 dBm)
