What is Fast PinPoint™ ?
PinPoint is a Park Systems’ unique AFM mode designed to measure nanomechanical properties including elastic modulus, adhesion and stiffness while simultaneously capturing high-resolution topography. By precisely controlling force and minimizing lateral movement, it ensures accurate measurement while effectively minimizing sample damage during measurement across diverse materials, from soft polymers to rigid composites.
Fast PinPoint advances the capabilities of traditional PinPoint by significantly increasing measurement speed without compromising accuracy. It provides rapid, high-resolution mechanical property mapping, making it ideal for analyzing dynamic or time-sensitive structures.
