Transmittance Meter

Using three-in-one optical path design, one hole can be measured 550nm visible light and 850nm/940nm infrared transmittance, the minimum test aperture is 1mm, and it is equipped with alignment indicator LED auxiliary alignment.

Light hole 2mm; accuracy up to +/- 1 %/ +/- 2%; can be tested by Measurement Institute; suitable for X-ray film, aluminized film, milky white, mist and other diffuse transmission material testing; can display light transmitance value and light density value.

Using three-in-one optical path design, it can simultaneously measure 430nm blue light, 395nm purple light and 380-760nm visible light transmittance, the test aperture is φ 1mm, with real-time dynamic self-Adjustment, small size and convenient operation.

Minimum test hole size 0.5mm, supports 550nm visible light and 850nm/940nm infrared transmittance measurement, with real-time dynamic self-Adjustment, Automatic calibration to 100% transmittance when powered on.

The parallel light path design can be used for the measurement of thicker materials; the three Light sources share a test hole, and the 380nm-760nm visible light transmitance, 940nm infrared and 365nm ultraviolet transmittance can be obtained in one measurement.
