Spectral Confocal Displacement Sensor Applications for Thin Film Thickness Detection




Thin films have a wide range of applications in industry and research, such as packaging materials, optical films, and electronic devices. The thickness of thin films is one of the key parameters affecting their performance and function. Therefore, it is very important to accurately detect the thickness of thin films.



Spectral Confocal Displacement Sensors are high-precision sensor devices that can be used to detect various types of thin films, including optical films, coating thicknesses, and more.



1. Optical films: Optical films have important applications in optical instruments, displays and other fields. Spectral confocal sensors can accurately measure the thickness of optical films to ensure their light transmission and color.



2. Coating Thickness: It is the film applied to the surface of the substrate. Such coating films are commonly used to improve the physical or chemical properties of the substrate. For example, gold plating, silver plating, electroplating and so on. Spectral Confocal Displacement Sensor can help us to detect the thickness of the coating, so as to ensure that the performance of the coating is guaranteed.



Using a spectral confocal displacement sensor to detect film thickness has the following advantages:



1. High-precision measurement: Spectral Confocal Displacement Sensor can accurately measure the thickness of the film, the measurement accuracy can reach the micron level, so as to ensure that the quality and performance of the film meet the requirements.



2. Non-contact measurement: Spectral confocal displacement sensor adopts non-contact measurement method, which will not cause any damage to the measured object, and at the same time, it can avoid the error caused by the contact, so as to ensure the accuracy of the measurement.



3. Fast Measurement: Spectral Confocal Displacement Sensor has the ability of fast scanning, which can measure multiple films in a short period of time, thus improving the inspection efficiency and reducing the inspection cost.
