Accurate measurement of film thickness and optical parameters is a key link in ensuring product quality and performance in fields such as semiconductor manufacturing, optical thin film research and development, and precision coating testing.Thetametrisis thin film thickness measuring instruments (such as the FR Scanner series) have become standard equipment in this field with their highly integrated optical module design - their optical modules not only accommodate all core optical components, but also achieve comprehensive breakthroughs in measurement accuracy, stability, and functional scalability through precision collaboration.

1、 The core component of the optical module is the integration of all link optical components
The optical module of Thetametrisis thin film thickness measuring instrument is a highly integrated "optical center", which integrates key components such as spectrometer, composite light source (with a lifespan of up to 10000 hours), and high-precision reflection probe. Among them, the spectrometer is responsible for decomposing the reflected light by wavelength and accurately analyzing the spectral characteristics; The composite light source provides stable incident light covering a wide spectral range of 370-1020nm, ensuring multi band measurement requirements from ultraviolet to near-infrared; The high-precision reflective probe accurately captures the light signal reflected back from the surface of the sample, and its spot size (such as the standard 350 μ m, some modules can be reduced to<100 μ m) can be flexibly adjusted according to the characteristics of the sample. These components are designed with precise optical paths and mechanically fixed to avoid measurement errors caused by displacement or vibration in traditional discrete optical components, laying the foundation for high repeatability data acquisition.
2、 The technological advantages of integrated design: collaborative improvement of precision, stability, and functionality
1. Measurement accuracy and repeatability: The integration of optical modules reduces energy loss and signal interference in optical transmission. For example, the long lifespan (10000 hours) and stable output of the composite light source, combined with the high resolution of the spectrometer, result in minimal errors in the collection of reflectance data. Material display shows that the thickness data of 625 measurement points on an 8-inch wafer can be completed within 60 seconds, with a thickness accuracy of 1nm and stability of 0.05nm. The minimum thickness required for refractive index measurement is only 100nm.
2. Multi parameter synchronous analysis: The module not only supports thickness measurement, but also synchronously obtains optical constants such as refractive index (n and k) and color of the film, and provides real-time feedback on film uniformity through dynamic measurement function, providing multidimensional data support for material research and development.
3. Function expansion and compatibility: The integrated design reserves flexible interfaces, which can adapt to more than 600 pre stored material parameters, support offline analysis and free software updates, and can also be extended to the measurement of irregular samples or ultra large wafers through customized platforms (such as 450mm large-sized sample stage or X-Y scanning module).
3、 Wide coverage of application scenarios
From nanoscale thin films of semiconductor photoresist and dielectric multilayer structures, to micrometer level coatings of photovoltaic silicon wafers and liquid crystal display panels, to industrial quality inspection of optical thin films and polymer coatings, the integrated design of Thetametrosis optical modules enables them to meet the measurement needs of transparent, semi transparent, and partially opaque materials. Whether it is precision research and development in the laboratory or rapid quality inspection on the production line, this equipment can provide reliable guarantees for film quality control through "one-stop" optical measurement.
The optical module of Thetametrisis thin film thickness measuring instrument has redefined the technical standards of thin film measurement with highly integrated and precise collaborative design, becoming a core tool for promoting progress in the fields of nanomaterials and precision manufacturing.
