4 Typical Application
4.1 Absolute Power Measurement
Absolute optical power can be presented in two scales, namely logarithmic and linear scale. The
power in kW, W, mW, uW, nW, pW would be selected to show in the result.
If dBm is used for power unit, the reading is 10times of the logarithmic ratio of the input power to the
reference 1 mW, as described in this formula:
dBm reading =10*lg[input power/1mW]
Measurement Steps：
a) Connecting Device
Firstly, turn on the Bluetooth of the mobile device and the software. Click Bluetooth, a dialog box will
pop up as shown in Figure 34. Click scan, t "BIM-7603-0001" (different devices, different serial
number suffix ) would appear in the Device dialogue, select this as shown in Figure 35. The power
meter information would be observed in upper left corner, this means the power meter has been
connected.
Figure 34. Before Connecting Device Figure 35. After Connecting Device
b) According to the measurement needs to select the appropriate operating mode and unit, the
wavelength value is set to the wavelength of the light source to be measured.
Chapter 4
DOCID#: CD-M-BIM-76XX-B
U S E R M A N U A L
- 28 -
c) According to the intensity of the light to be measured, select the appropriate attenuator to
prevent the measured light intensity exceeds the saturation and damage threshold detector.
Note: When using the detector plus attenuator, be sure to open the attenuator. Otherwise it will
cause the incorrected display.
d) According to the testing needs, select the appropriate stop mode, set the sampling duration and
interval.
e) Shield light source to be tested.
f) Click Zero, clear the initial background signal. The reading should be close to zero, but the reading
will actually fluctuate up and down depending on the light flux reaching the detector and the dark
voltage of the detector.
g) With the detector to be illuminated by the source to be measured, click start to record the data.
h) To re-measure, click and return to step b to reset. (Repeated in several parts, should still keep
this?)
Notes
Minimize the impact of stray light and reduce stray light from the following factors, such as switching off the
house lights, remove the people and other equipment. Do not focus the light on the detector surface, this may cause
incorrected readings and damage to the detector. Check any saturated results and damage thresholds in the relevant
manuals.
Select dBm as the absolute power measurement unit. It is necessary to ensure that the measured light source
power value is always greater than the background power value PZ. Otherwise, the readings of dBm are meaningless
and cannot be collected.
4.2 Relative Measurement
dB is the unit for the input power / reference power ratio (the reference power is the stored power
value after click Delta). This can be calculated by the following equation:
DB reading = 10 * lg [input power / reference power]
= 10 * lg {[(P
Abs
- PZ)] / [(P
ref
- PZ)]}
P
Abs
: absolute power value to be measured
P
ref
: reference light absolute power value
PZ: value of the background light power at zero
Testing procedures:
a) Connect the equipment according to the procedures for absolute power measurement;
b) Select the proper measurement mode and unit, and input the wavelength for the source to be
measured;
c) Select the proper attenuator in order to limit the light source intensity from saturation and
damaging the threshold detector. Note: Open the attenuator before measurement, otherwise,
incorrected display would be occurred;
d) Select the appropriate stop mode, set the sampling duration and interval;
e) Shield light source to be tested
f) Click “Zero” to clear the background signal. The reading should be close to zero, but still oscillate
DOCID#: CD-M-BIM-76XX-B
U S E R M A N U A L

due to the light flux reaching the detector and the dark current in the detector.
g) Relative measurement can be activated y irradiating the detector with reference light
h) Click Delta, the reference signal power value P
ref
would be saved and in the relative measurement
mode automatically.
i) Place the light source to be measured, click start to record the data.
j) For next measurement, click reset and repeat the steps from (b).
Note
The reference light and the measured light must be measured in the same condition, i.e. the background light PZ
try to keep consistent before and after setting zero. This can guarantee that the reference power and the
measured light source power value are always greater than the background as cleared PZ. Otherwise, there is no
meaning for dB readings, the data acquisition needs not be conducted.

5 How to use
5.1 Calibration Service
Every detector must be well calculated and set properly before sending to customer. Nevertheless, it
is recommended to calibrate the detector once per year in order to keep its accuracy. This calibration
service is available by our team. The calibration results would be sent to the customer in a calibration
report, and the detector would be set accordingly.
5.2 Consistency
The spectral responsivity over the area on each detector may not be consistent due to the
manufacturing variations. Thus, 70% effective area at the detector center would be employed for the
calibration, as the lights irradiate in the same area. By this means, the accuracy can be guaranted, so
the entire detecting area won’t be exposed to the light.
5.3 Cleaning
Do not touch the detector surface directly with fingers. Surface contamination is leading to inaccurate
measurements.
5.4 Storage Temperature and Humidity
The operation temperature is suggested to keep at 23℃ which is the same as the calibration
temperature. The storage temperature should be between 5 ℃ - 50 ℃, relative humidity should
not exceed 70%, and contamination-free environment.
