Following the initial internal customer experience sessions at the Shanghai Munich Photonics Expo, Atometrics has officially launched its new flagship white light interferometer, the AM8000. This white light interferometer enables sub-nanometer level measurement of various precision parts and material surfaces, capturing 3D surface topography with measurement accuracy of less than 1nm.

Across the three key dimensions of application scenarios, intelligent operation, and measurement stability, the AM8000 is fully comparable to flagship products of top global brands. This signifies that Chinese brands have achieved core technological breakthroughs in the field of high-precision white light interferometry, thereby helping to propel China's intelligent manufacturing industry to further overcome core technological bottlenecks, enhance high-end supply, and support the construction of a manufacturing powerhouse and a quality powerhouse.

Compatible with More Lenses and Measurement Samples

Meeting the Demands of the Semiconductor, Precision Optics, and Other Industries

Currently, domestic white light interferometers on the market are primarily equipped with short focal length, small field of view lenses. The Atometrics white light interferometer AM8000 supports compatibility with a wider range of magnifications, such as a 1X long focal length, large field of view lens, achieving a single field of view of 18 × 11 mm, effectively addressing the need for large-area measurements. It also supports long focal length 5X and 10X lenses, with focal lengths reaching 40mm and 22mm respectively, enabling measurement of samples with large hole depths like fuel injector nozzles. The expanded lens compatibility allows the AM8000 to meet the measurement requirements of more specialized parts. Additionally, the AM8000 features adaptive lens travel, ensuring that after mounting different lenses, collisions with the measurement object due to incorrect operation are prevented.

The AM8000 is equipped with a 4-degree-of-freedom direct-drive electric control stage, with a maximum XY travel of up to 300mm, a 2.5-fold increase in load capacity, a 30% increase in stitching movement speed, and a 3-fold improvement in positioning accuracy. For white light interferometers, meeting the needs of a wider variety of sample specifications requires increasing the stage travel; however, increased travel can introduce uncertainties that affect accuracy. The electric control stage of the AM8000 achieves large travel while maintaining motion straightness of ±1um and angular deflection ≤5 arc seconds. Furthermore, the AM8000 can be equipped with a rotary stage to meet the mapping measurement requirements of wafers.

Additionally, the AM8000 incorporates functions such as cyclic measurement, batch export of measurement reports, focus curve, and ROI extraction and evaluation. It also features over 300 measurement tools, including surface roughness, profile analysis, texture direction, particle analysis, texture homogeneity, etc., to better meet application requirements across various industries.

One-Click Focus + Leveling

Improving Operational Efficiency by 7 Times

In white light interferometer operation, the most tedious and time-consuming steps are manual focusing and leveling. These often rely heavily on the engineer's experience and raise the barrier to operating the instrument. The AM8000 introduces the "PreciTrack Stripe Auto Focus" function. Engineers simply place the object and click one-click focus, completing focusing and interference fringe searching within 5 seconds—an efficiency 7 times faster than manual focusing. For leveling, the AM8000 features the industry-first "EquiDrive Auto Leveling" function, which completes leveling within 5 seconds, reducing the number of interference fringes within the measurement range to 1 or 0, achieving efficiency 8 times faster than manual leveling.

For measuring large-sized parts, the AM8000 offers a variety of stitching patterns, such as square/rectangular, circular, and annular. Engineers can directly input values to automatically generate the required stitching area. For batch measurement of samples, the AM8000 supports multi-point programming measurement, automatically positioning and measuring based on the sample coordinates, eliminating the need to manually place each sample.

The AM8000 also adds a controller module, integrating functions such as stage movement, light source adjustment, and focusing onto the controller. Engineers can perform routine operations with a single click, improving work efficiency by 50%.

Built-in Air Flotation + Low Center of Gravity Mechanism

Vibration Isolation Stability Increased by 2.7 Times

White light interferometers are precision measurement instruments; external vibrations or accidental operator contact with the device can easily affect measurement results. Consequently, many organizations provide a stable environment for their white light interferometers, significantly raising the barrier to application. Reducing environmental impact has become a key direction for leading global brands in improving device performance.

To address this issue, the AM8000 employs a built-in air flotation isolation mechanism, encasing the entire vibration isolation system and worktable. Combined with a uniquely designed low center of gravity, it significantly reduces the impact of environmental vibrations on the device. Tests show that the AM8000's vibration isolation stability is increased by 2.7 times, achieving RMS repeatability of 0.0041nm.

Furthermore, the AM8000 is equipped with a 5000um large-range piezoelectric ceramic, a 5-megapixel high-speed camera, and incorporates the industry-first SST + GAT algorithms, supporting PSI (Phase Shifting Interferometry) and VSI (Vertical Scanning Interferometry) for instantaneous sub-nanometer data acquisition.

Currently, the AM8000 can be applied in fields such as new energy, automotive, 3C electronics, semiconductors, precision optics, micro/nano machining, medical devices, friction and wear, etc. Application examples include copper foil/aluminum foil roughness measurement, perovskite coating thickness measurement, photovoltaic grid line height measurement, gear surface roughness measurement, plow-type groove cross-sectional area measurement, precision polished surface roughness measurement, advanced packaging topography analysis, ceramic substrate step height/flatness measurement, ultra-smooth roughness measurement, microfluidic chip topography, implant topography/roughness, intraocular lens topography/roughness, and more.

Having achieved significant advancements across the three key dimensions of application scenarios, intelligent operation, and measurement stability, the AM8000 is now fully capable of competing with flagship products from top global brands. This underscores that Chinese brands have realized core technological breakthroughs in the field of high-precision white light interferometry, helping to liberate China's intelligent manufacturing industry from foreign technological constraints, enhance high-end supply, and support the construction of a manufacturing powerhouse and a quality powerhouse.
