Don't worry about the quality of thin films/polarizers, and the translucent size measuring instrument helps you (KEYENCE)

Light curtain transmissive dimensional measuring instrument × warpage detection

The polarizer is made by laminating the upper and lower TAC and PVA. However, due to the water absorption, heat shrinkage, elongation, and thickness differences of TAC, the overall warpage of the polarizer will be poor after drying. Due to the wide variety of polarizer sizes and the uncertain warpage position, traditional dimensional measurement tools cannot accurately detect the degree of warpage, while manual inspection cannot achieve full inspection and is labor-intensive.

Today, we recommend the LS series light curtain transmissive size measuring instrument for the detection of polarizer warpage.

In addition to polarizers, the LS-9000 series can be used to detect curl in materials that are prone to curl after cutting, such as film and film.

Film/film measurement – easily with a through-feed dimensional measuring instrument

The gap of the roll has a great influence on the thickness of the film material. In the past, workers used thick gauges or micrometers to adjust gaps. The production line must be stopped when using a thickness gauge, while the indirect measurement method is required for the use of a micrometer, and it takes time to make adjustments because the actual gap is not understood. The LS-9000 series gauges are non-contact, so they can measure even during production line operation, so they can effectively reduce adjustment time and improve quality.

In addition, if the width of the film is not fixed or the film is bent during the film production process, not only will it become a defective product, but it will also become messy during the subsequent winding process.
