Transmittance Meter | Is it Necessary to Film Glass?
Window film, as one of the most commonly used protective materials, has great market and practical value. As one of the important properties of window films, light transmittance is often a part of people's attention and detection. But we can't judge its specific light transmittance with the help of eyesight and it is generally tested with a transmittance meter.
In addition to the better protection of window film, it can also be a strong thermal insulation. Some window films added with special substances (gold, silver, copper, etc.) can also be made into explosion-proof films with excellent results. After a period of renewal and change in the window film manufacturing industry, the internal performance of window films has also been greatly improved. Some new window films can even change color and fog, which largely meets the needs of modern people.
In our daily life, the most common use of window film is to make a car glass film. As we all know, the temperature inside the vehicle is very high and the temperature rises very quickly in the summer. A large part of the reason is that the front windshield of the vehicle has strong light transmission ability. Therefore, many car owners will choose to stick a window film to reduce heat ingress and prevent ultraviolet radiation. In particular, it should be pointed out that the excellent window film can block 99% of ultraviolet rays.
So, is it necessary to stick window film? Objectively speaking, sticking window film really meets the needs of most people driving for a long time. However, the selection of window film with good effect and high cost performance is a science and it needs the help of light transmittance meter.
We know that many window film surfaces will have a layer of color. The darker the color, the better the heat absorption effect. The lighter the color, the better the transmitting light effect. So many people think that the darkest color should be chosen since it is fully insulated. When we consider the performance of window film insulation and radiation protection, we must also consider the biggest problem: personal safety.
The darker the color of the window film, the lower the light transmittance. On some poorly lit roads, it is easy to ignore pedestrians on the roadside. Especially when driving at night, the window film with low light transmittance becomes a driving obstacle. In addition, the level of light transmittance directly affects driver's eye fatigue. After the window film is applied, it will bring a sense of burnout to the driver. Long-term passage of the low-light transmittance front glass will fatigue the eyes and increase the danger of driving.
In addition to the consideration of the driving quality in life, the light transmittance of car glass with window film is not allowed to be less than 70%. This can be said to be a compulsory regulation, which is a guarantee for the driver's life. Therefore, the function of the transmittance meter is greatly reflected here, it can tell us very professionally whether the transmittance of the window film has reached the prescribed standard.
Linshang transmittance meter is not only suitable for the above two situations, it is also applicable to other industries that need to measure the light transmittance of products. The accurate detection of the transmitted light intensity of transparent products also depends on the correct operation method of the inspector.
