Profilometer For Large Area Measurements
Meet the ST500 Profilometer. After years of success with the ST400 and HS1000 Nanovea introduces the ST500 providing high speed large area measurement without stitching. The ST500 has a 400 mm X-Y Axis Travel, a 50 mm Z Axis with a maximum speed up to 200 mm/s. The system can be equipped with either an optical pen or line scanner for ultra fast measurement (384,000 points per second). Unlike other technologies, each point is a direct, full depth of field during large area measurement without the need of refocusing. A video zoom camera can also be used to provide automatic function to large area measurement complete on a desktop user friendly platform. See app note for example.
Scratch Adhesion Testing of Disc Coatings
In this study, instrumented scratch testing is used to assess the failure modes of the top layers of CD and BD. This test allows users to quantitatively compare the scratch resistance of different protective coatings.
Wear Evaluation by High Load Tribometer
The Macro Tribometer is designed with high torque capability for loads up to 500 N. In this study, we simulated and compared the wear behaviors of valve coatings under high loads to showcase the capacity of Nanovea Macro Tribom
eter in quantitatively evaluating the wear properties of materials such as wear rate and coefficient of friction.

• Wear testing of enriched teflon
• Wear testing of nylon composite
Corrosion Profilometry Is Application Of The Year
With the Nace Corrosion Conference only weeks away Nanovea highlights pitting corrosion measurement as its most popular profilometry application of 2014. The Nanovea Profilometer has quickly become the choice in the corrosion community for its accurate and reliable measurement. Primary area of interest include pitting depth, volume, area and density.

Hardness Distribution of Hardened Metal Using Nanoindentation
In this application, the Nanovea Mechanical Tester in nanoindentation mode is used to measure the
hardness distribution of the hardened surface on the cross section of a surface hardened metal.

Hard Metal Wear Evaluation Using Tribometer
In this study, we simulated and compared the reciprocating wear behaviors of saw blades to
showcase the capacity of Nanovea Tribometer in measuring the coefficient of friction and wear
rate of surface hardened metals in a controlled and monitored manner.
Corrosion Surface Analysis Using 3D Profilometry
In this application the Nanovea PS50 Profilometer is used to analyze the surface morphology of the
samples after service in corrosive environment. Surface roughness, materials loss and pits on the
sample surface are measured to provide more insight in the corrosion mechanism.
