Transmittance Meter Tells You the Mystery of Frosted Glass

Compared with ordinary glass, frosted glass not only has a high light transmittance, it is characterized by opaque light transmission to protect people's privacy. This light transmittance is generally tested using transmittance meter.

There are many types of glass on the market. Even the same glass will have different transmittances due to different formulas. Under normal circumstances, only the transmittance meter can accurately detect the light transmittance of the glass. Frosted glass has high light transmittance and good decorative performance.

From the appearance, frosted glass is smooth on one side and rough on the other. From the perspective of light transmission, this kind of frosted glass has excellent light transmission performance and good decorative effect. It can also be polished into different degrees of rough surfaces. From the perspective of processing technology, the plasticity of frosted glass is high. It can be easily implemented whether it is matting modification or brightening modification.

Glass transmittance is what we often say about the ability of glass to transmit light. Generally speaking, glass with higher transmittance means that it refracts and absorbs less light, but most of the light is transmitted into the house. This is the main performance of most glasses. Frosted glass has the advantage of being opaque compared to ordinary glass. This advantage allows people to clearly see the outside world inside the house, while people outside can't see through the glass. This not only continues the traditional characteristics of glass, but also greatly protects people's privacy and gives people more choices.

Many people will ask, why can frosted glass be opaque? This also requires a professional transmittance meter to give us an answer.

In glass manufacturing plants, we will find that frosted glass will be sandblasted to form a rough film on its surface. This is a very common physical method. The chemical method is to use a hydrofluoric acid solution (HF) to frost the glass on one side or on both sides. After a relatively long period of time, the glass is taken out for cleaning. It is easy to find that the light transmittance on the light surface is extremely high by using a transmittance meter.

Compared with ordinary glass, frosted glass is transparent because its front and back sides are very flat and smooth. The light reflection is on both sides and the light does not have any damage and offset. Frosted glass has a very rough surface, the light passing through the surface will be refracted, and the direction will also change.

Is the transmittance of frosted glass lower than ordinary glass? the answer is negative.

When we use the transmittance meter, there will be an intuitive comparison. This frosted glass is both transparent and beautiful. If you want a higher light transmittance, you can also paste cellophane. Applying glycerin to the rough surface of frosted glass will also increase its light transmittance.

transmittance meter

The transmittance meter developed by Linshang Technology can accurately detect the light transmittance of frosted glass. It can also provide a reference for gloss modification for some glasses with lower detection values. In the actual measurement, the operation method of the transmittance meter is simple and easy to understand. It has a wide measuring range and is suitable for the transmission test of various frosted glass.
