Affordable & Accurate Optical Profilometry

The Filmetrics Profilm3D is a low-cost optical profiler system, designed with state of the art white light interferometry technology. Options are also available for phase shifting interferometry. The Profilm3D can produce high-quality surface topography from sub-nanometre to millimetre ranges, and capture infinite depth of field True colour images.

The Profilm3D hardware platform has a comprehensive range of features, and is expandable and upgradeable. An automatic XY stage with 100mm of travel and tip and tilt function is included as standard. An optional 200mm travel stage is also available with the Profilm3DPlus. The Profilm3D also features a 4-position turret, and has an exceptionally wide field of view – 2mm wide with a 10x objective.

Intuitive Profilm & ProfilmOnline Analysis Software

Filmetrics’ Profilm software is a fully featured and intuitive to use software package for viewing and analysing Profilm3D images. The Profilm3D is also fully supported by ProfilmOnline, a cloud-based software platform providing access to profiler images and data from anywhere – even on a smartphone or tablet. ProfilmOnline can also be used to share images and collaborate on analysing data with other users.

The Profilm desktop software includes a comprehensive range of features. A variety of levelling and liftering options are provided to enhance accuracy and clarity. Surfaces can be analysed with line, rectangle, and histogram step heights, and all 47 standard ASME/EUR/ISO roughness parameters. Profilm provides powerful 3D visualisation capabilities to provide the best view of a sample’s surface.
