    Spectrum Genius Transmittance provides you friendly UI and rich information critical to everyone check the transmittance of object. You can get the Original Spectrum, Reduction Spectrum, Average Transmittance, Assigned Transmittance, and Assigned Rejection by a quick measurement.

    APP Control Steps

    ■ Step 1: Tap the “Measure” button to get the original spectrum of the light source.


    ■ Step 2: Put “the object under test” on, then tap the measure button again.

    ※ The object under test can be lens, panel materials, filter, screen protector, and etc..

    ■ Step 3: After done, you can get the spectrum of original light source and reduction of light, and the transmittance values of whole visual wavelength.
