Surface Profile Analyzer SPA 25

Product catalog summary

Introduction
The Surface Profile Analyzer SPA 25 is designed for measuring surface topography and roughness parameters with high speed and resolution. It employs white-light interferometry for superior height resolution, offering advantages over other techniques like focus variation and confocal microscopy.

Specifications
The SPA 25 features a motorised sample table for precise positioning and automatic movement, allowing for the analysis of larger surface areas up to 300 mm x 300 mm. It uses MountainsMap® Imaging Topography software to calculate surface texture and profile roughness parameters according to industry standards such as ISO 25178 and ISO 4287.

S u r f a c e P r o f i l e A n a l y z e r S PA 2 5 The Surface Profile Analyzer SPA 25 can measure surface topography and roughness parameters with exceptional speed and resolution. High resolution measuring technique height resolution / system noise [nm] The SPA 25 utilises the white-light interferometry technique that features a height resolution of down to 0.1 nm even with small magnification factors. This gives the SPA 25 a significant advantage over rivalling systems that use other techniques like focus variation or confocal microscopy. focus variation confocal microscopy white-light interferometry...
