The light transmittance meter is a relatively new word for everyone, but the light transmittance is not unfamiliar to the general public. Our common glass, plastic and film all have a certain degree of light transmission. Thin film can pass natural light and artificial light well. Under normal circumstances, the production industry uses a light transmittance meter to control the light transmittance of light transmitting products.

1. The principle of light transmittance meter

The working principle of the light transmittance meter mainly uses a beam of visible light. When this beam of light is irradiated on the detected object, refraction and transmission occur. The ratio of the transmitted light to the incident light source is what we call the transmittance. The detection of the general light transmittance meter is based on the percentage, which is suitable for various forms of light transmission products.

2. Application of light transmittance meter in different industries

LS110 light transmittance meter is easy to operate and its measurement accuracy is very strong, it is used in practical production by most industries. Products in each industry require different light transmittances, so the specific standards for testing also vary greatly. We use the light transmittance meter in the fields of automobile manufacturing and testing and solar film testing as examples to briefly explain the actual use of the light transmittance meter.

(1) The role of the light transmittance meter in the field of automobile manufacturing and testing

In the field of automobile manufacturing and testing, a light transmittance meter is often used to detect the glass transmittance of automobiles. Automotive glass, as one of the most important parts of a car, plays a protective role. In our country's vehicle quality inspection department, the glass transmittance requirement of the vehicle is not less than 70%. If it is lower than this value, the low light transmittance of the vehicle will affect the driver's sight and vision.
        Therefore, when the owner uses a light transmittance meter to test, the light transmittance of the glass is often controlled at about 80% in the case of self-test. 

(2) The role of the light transmittance meter in the field of solar film

The main use of solar films is heat insulation. In theory, dark solar films often absorb too much light and have low light transmission. People often choose light-colored solar films with high light transmittance. Quite a few good quality products on the market can also effectively block the ultraviolet rays in sunlight and truly prevent radiation. Most of the solar film is made into a car film, which is used to protect the vehicle and is resistant to heat. The permeability of the solar film is an important consideration parameter and we generally use a light transmittance meter to measure it.

3. Significance of the light transmittance meter

For different industries, the use of a light transmittance meter can achieve a high degree of quality control and enhance the control and adjustment of product light transmittance. It's easy to use and doesn't have many constraints. It can reflect the light transmittance of the product in a short time, which has a strong guiding significance.
        On the one hand, the light transmittance meter has a very powerful measurement performance, with a wide range of applications and excellent results. On the other hand, modern intelligent light transmittance meters are designed to be compact and portable. This is of great practical significance to the self-inspection and quality inspection departments in the industry.
