A digital refractometer is an instrument used to measure the refractive index of a substance. It works by shining a beam of light through a sample and measuring the angle at which the light is bent. The refractive index is then calculated based on this angle and the properties of the material being measured. Digital refractometers are commonly used in the food and beverage industry to measure the sugar content of liquids such as fruit juices and wine. They are also used in the automotive and chemical industries to measure the concentration of various fluids. Digital refractometers offer the advantage of being more accurate and easier to read than traditional analog refractometers.

Closed cell aluminum foam panels with punched holes
We also can punch holes on the closed cell aluminum foam panel(hole diameter is 1mm and hole distance is around 10mm, please see the following picture), which has almost the same effect on sound absorption and installation method as open cell aluminum foam panel.
Besides, closed cell aluminum foam panels are also used to composite with a thin layer of other materials, such as aluminum sheet, marble, etc.
