I. Product Introduction
Lens transmission meter use infrared light sources of 850nm and 940nm and a visible light source of
550nm to illuminate the transparent material under test. The sensor detects the incident light intensity of
the three light sources and the light intensity after passing through the transparent material under test.
The ratio of the transmitted light intensity to the incident light intensity is the transmission, expressed as
a percentage.
II. Parameters
1. IR peak wavelength: 850nm and 940nm
2. VL peak wavelength: 550nm
3. Test hole diameter: ￠1mm/￠0.5 mm
4. Resolution: 0.1%
5. Measurement accuracy: ±2% (colorless and uniform transparent material，0-90% transmission)
6. Display:480*270 dot matrix color screen
7. Power input: DC5V/1A
8. Dimensions: 170mm ×180mm ×144mm (L*W*H)
9. Weight: about 1570g
III. Operation
1. Power on self-test
Power on: Plug in the power supply and ensure there is no test sample under testing. Short press the "
" button to turn on the meter. The boot interface displays the version number and serial number of the
meter and then enters into the measurement interface.
Power off: Short press the “ ” button to turn off the meter in the measurement interface; Long press
the “ ” button for 3s to turn off the meter in the setting interface.
2. Setup

the 940nm infrared transmission;
Short press the " " button to confirm the setting and return to select the setting item.
C. Select "Exit", short press the " " button to exit the setting mode and enters into the
measurement mode.
3. Measurement and operation
After powering on, the meter enters into the measurement interface, all transmission data is displayed as
100%. The test sample is placed on the test hole, the LCD screen displays the visible light of 550nm,
infrared light of 940nm and 850nm of the test sample;
As shown in the figure below: The infrared transmission of 850nm is 69.5%, the visible light
transmittance of 550nm is 18.6% and the infrared transmission of 940nm is 74.4%.

4. PC software counting statistics function
The meter has a USB interface and provide PC software to complete the functions such as the
inspection quantity counting, pass rate, pass and fail judgment during the production testing process. For
details, please refer to the PC software and software user manual in the attached U disk.
5. Abnormal voltage prompt
Voltage> 5.7V or <4.7V, the meter enters into the abnormal voltage interface. The meter automatically
turn off after 2s; when the interface prompt appears, please follow the prompts to replace the appropriate
power supply.
IV. Features
1. Brand new wavelength synthesis technology, measure transmission data of 3 wavelength
simultaneously.
2. Obtain the visible light transmission of 550nm, infrared light transmission of 850nm and 940nm at the
same time by aligning the test hole just once, which greatly improves the test efficiency.
3. The test hole has an alignment indicator LED, which is used to help the alignment of the tested lens
hole during the testing process.
4. Suitable for testing infrared transmission and visible light transmittance of mobile phone lens.
5. The meter has real-time dynamic self-calibration function, which automatically calibrates to 100%
transmittance after powering on.
6. Large LCD display. Three Chinese display interfaces or three English display interfaces can be
selected.

V. Notes
1. The meter is self-testing and self-calibrating when it is turned on. Please don’t place any test sample
in the test position, otherwise the self-calibration cannot be completed.
2. Avoid contact with corrosive materials and keep away from high temperature and high humidity
environment.
3. When there is no test sample, the display data occasionally cannot return to "100%". Just shut down
and restart the meter immediately for normal use，it does not affect the measurement accuracy.
4. When the meter is not in use, please turn it off.
5. When the interface displays abnormal voltage, please replace the power supply.
