The Dual-Core 3D Measuring Microscope Leica DCM 3D combines confocal microscopy, interferometry and color imaging in one sensor head. Designed for R&D and quality labs or automatic online process control, the system offers fast and contact-free analysis of the micro- and nanogeometry of material surfaces to an accuracy of 0.1 nm. A confocal microdisplay, two light sources and two CCD cameras produce unlimited field depth and highly precise 3D results. As it requires no mechanically moving parts, the DCM 3D is practically maintenance-free.

To image and measure small structures, forms and surface roughness has become more easy, fast and versatile with the Sensofar PLµ Neox, distributed by the Schaefer-Tec group. The optical profilometers of the PLµ series combine the two complementary measuring techniques of confocal microscopy and interferometry in one and the same instrument. With this, high resolution 3-D imaging and dimensional measurements of nearly all kinds of surfaces are obtained easily and fast.

Schaefer-Tec launched the new Sensofar PLµ NEOX optical profiler that combines the complementary measuring methods confocal and interferometry in one instrument. The integrated piezo scanner provides a vertical resolution of down to 0.01nm in the Phaseshifting Interferometry mode while the linear stage allows for up to 40 mm vertical scanrange. Sensofars patented microdisplay-based confocal scanning technology works without moving parts and guarantees a very long lifetime without maintenance.

Confocal technique and white light interferometry have demonstrated to be suitable for characterization of transparent thick films. Layer's thickness and 3D topographies of its upper and lower interfaces can be determined from the two peaks in the confocal axial response or from the two sets of interference fringes developed during a vertical scan. Refraction index mismatch between immersion medium and layer worsens the performance of these techniques when profiling lower surface.
