What is acrylic sheet

Acrylic is also called special-processed plexiglass. It is a replacement product of plexiglass. The light box made of acrylic has good light transmission, pure colors, rich colors, beautiful and flat, taking into account the two effects of day and night, long life, does not affect the use, and other features.

How to calculate transmittance

In the process of measuring the haze and light transmittance of the sample, it is necessary to measure the incident light flux (T1), the transmitted light flux (T2), the scattered light flux (T3) of the instrument, and the scattered light flux (T4) of the sample.

Calculation method of Transmittance: Tt= T2/ t1x100%

How to calculate haze?

Haze: H= [t4-t3 (T2/T1)]/ t2x100%

The formula of haze value H can be simplified as: H(%)= [(T4/T2)-(T3/T1)]×100%

How to Measure Acrylic Plastic Sheet?The products that measure haze are Color Spectrum TH-100, CS-700, CS-701 and CS-720

Take Color Spectrum Haze Meter TH-100 as an example


Connect the instrument to the power source, press the power key, the indicator light is always blue, and the instrument starts normally.

2.0% and 100% calibration.

Put the 0% calibration cover on the test port so that the integrating sphere does not receive any light. Press the OK key on the side of the instrument to calibrate.100%: Keep the test port open, let the light from the light source pass through the test port, and press the OK key on the side of the instrument for calibration.


After calibration, place the transparent acrylic plastic sheet in the test port and click the test button next to the instrument. The result will be available in 2 seconds. The operation process is very simple.
