1. The test aperture of this lens transmission meter is 0.5mm. Materials whose size are larger than 0.5mm can be measured.

2. The three light sources share a test hole. Three data can be obtained by measuring for just one time. Easy to operate and save time.

3. The test hole has an LED light for alignment, which is used to align the hole with the mobile phone lens during the test.

4. The transmission meter has real-time dynamic self-calibration function which can automatically calibrated to 100% transmittance after starting.
