Evaluating the Color of Transparent Films

Color measurement technologies are tasked with some of the most difficult jobs when it comes to transparent and semi-transparent films. Mostly because the films' visual properties are contingent on color, the transmission of light, and the haze surrounding the light.

3nh has advanced packaging tools such as spectrometers which makes it easy to assess and provide color example for transparent films that are used in packaging, protective laminates, and covers for important materials. The tool evaluates the light used in the material and the color packed to determine the color and uniformity in the film and helps to identify defects and uneven thickness of the film to maximize light use when packed.

Using Haze and Light Transmittance Meters to Test Greenhouse Films

Greenhouse films need to have the right balance between light transmission and diffusion for the best plant growth. If there is too much light haze and diffusion, the plant will not be able to photosynthesize. If there is too little, the plant will overheat and light will be unevenly distributed to the plant.


3nh Haze Light Transmittance Testers designed to measure and evaluate the above described parameters. They measure total and diffused transmittance which helps the producer design crop films that best suit specific crops and climates.


The ability to measure how a film responds to light promotes innovation in the agricultural industry, and helps the greenhouse covering facilitate optimal growth.
