Non-contact evaluation of sub-nanometer surface roughness on audio metal components | White light interferometer for metal part roughness | Atometrics

The surface roughness of audio metal components directly affects visual and tactile quality, assembly fit and the acoustic performance of the cavity, and acceptance is typically based on the areal roughness parameter Sa. Conventional contact-type roughne

White Light Interferometer Measurement Modes: VSI vs. PSI (Vertical Scanning Interferometry and Phase-Shifting Interferometry)

White light interferometers perform 3D topography measurement on different types of surfaces through two modes: Phase-Shifting Interferometry (PSI) and Vertical Scanning Interferometry (VSI). This article compares the two modes in terms of principle, res

Diamond wafers for advanced process nodes: It all starts with thickness control.

As ultra-thin wafers become increasingly common, their mechanical brittleness rises significantly once the thickness drops below 50 μm. For wafers made from third-generation semiconductor materials—such as SiC and GaN—which are characterized by high hard

Precision Inspection of Glass Substrates: Atometrics Solution Improves Yield to 90%

Atometrics white light interferometer (accuracy 0.03nm) & ultra-depth-of-field microscope - a high-precision inspection solution, helps improve the yield of glass substrates to 90% and accelerates the process of industrial upgrading.

Roughness and flatness: two unavoidable challenges for Faraday rotation glass

The Faraday rotatable plate is the core crystal element inside an optical isolator, acting as a "one-way valve" in the optical module. Its crystal quality and surface condition directly determine the isolator's insertion loss, isolation, and power handli

microchannel

Introducing white light interferometers to control the morphology of microfluidic chips significantly improves performance.

White light interferometers enable nanoscale control of microfluidic chip surface roughness, as well as microchannel height and width, improving the performance and quality of microfluidic products and meeting the needs of different customers.

The quality of heat dissipation in an optical module can be determined by a difference of 0.1 micrometers in the roughness of the liquid cooling plate.

With the rapid development of AI, heat dissipation of optical modules has become a crucial problem to solve, and liquid cooling has become the mainstream solution. At this time, the roughness of the liquid cooling plate can affect the heat dissipation sp
