Introduction

 LS108D lens transmittance measuring instrument is specially used for mobile phone lens transmittance test, as well as IR hole infrared transmittance test, the instrument test aperture is 0.5mm, can test 550nm transmittance and infrared 850nm, 940nm transmittance. The instrument has a real-time dynamic self-calibration function, which is automatically calibrated to 100% transmittance after powering on, and the test aperture of this mobile phone lens Tester is very small, and the application range is very wide. In 2018, the LS108D lens transmittance measuring instrument was upgraded and computer software was given as a gift, which can realize functions such as automatic counting, automatic judgment of qualified and unqualified products, etc. The test principle of the instrument is that the light source irradiates the measured transparent substance, and the sensor detects the incident light intensity of the three light sources and the light intensity after passing through the measured transparent substance, and the ratio of the transmitted light intensity to the incident light intensity is the transmittance, which is expressed as a percentage.

Features

1. The minimum test hole size is ¢0.5mm, and the IR hole of the mobile phone with an aperture greater than 0.5mm can be measured.

2. Each of the three test holes has alignment indicator LEDs for alignment of the holes of the mobile phone lens during the test.

3. Stainless steel desktop design, exquisite appearance, conducive to the placement of the measured object, easy to operate.

4. The instrument has a real-time dynamic self-calibration function, which is automatically calibrated to 100% transmittance after powering on.

5. On the stainless steel table, glue and fix a lens positioning piece, which is convenient for batch testing of lenses on the production line.

6. The instrument has a USB interface, free computer software, complete the production testing process of the test quantity, pass rate, pass and fail judgment and other functions, please refer to the attached U disk in the software and software operation manual.

7. Switchable function between fast measurement and slow measurement: fast measurement function is suitable for batch inspection with positioning device on the production line, which can greatly improve production efficiency, slow measurement is more suitable for manual alignment of test holes, the light source flicker is slower, and the test holes can be better seen and aligned.


FAQ
QWhat is the lifespan of the LED lamp beads in the light transmitter?
A LED lamp beads, the service life given by the manufacturer is 100,000 hours, but due to our use environment, the number of switches and other reasons, the actual use of lamp beads will occur Light intensity attenuation, especially UV Lamp beads, is the most prone to attenuation Light source. Regular use for three to five years is no problem.
QMeasurement of light transmitance, the difference between 380-760nm and 550nm
A The data of 380-760nm is the transmittance of all wavelengths in the entire range, which conforms to the value calculated by the CIE bright vision function standard. The 550nm light transmitter only tests the transmittance of the 550nm wavelength point.
QAfter two tests, the transmittance data changes at the same location of the test sample. What's going on?
A Before and after the two tests, the change of Measuring location may not be visible to the naked eye, but in fact the location of the test must be slightly different. For materials with uneven transmittance, it is normal for the subtle change of Measuring location to cause the data to change.
QTransmission instrument, remove the sample, the data of the instrument cannot be restored to 100%?
A This happens because there is interference from external light in the measurement process, just shut down and restart the instrument, restore to 100%, and then it can be used normally.
