The μSurf explorer compact optical 3D measuring instrument is for measuring and analyzing surfaces. The measurement is based on confocal technique.

μSurf explorer can be used for DIN EN ISO compliant roughness determination, analyses of 3D structures, layer thickness and measurement of geometry in the micrometer and nanometer range.

μSurf explorer is very robust and environmental influences, such as vibrations, dust or splashed water do not affect the precision of the measurement results. μSurf explorer is ideal for a broad spectrum of materials. Almost all surfaces, from polymers to metals through to composite materials, can be transformed into precise measurement data. No sample preparation is required for measurement.

μSurf explorer offers a nanometer precision resolution. This is based on confocal Multi-Pinhole-Technology in combination with the precise piezo module. Rough surfaces and structures with steep flank angles can be captured reliable and even strongly reflecting can be transformed into measurement data error-free. The objective lens used offers individual measurement field sizes between 1.6 x 1.6 mm and 260 x 260 μm with freely selectable vertical resolution. After each measurement real 3D data are available and μsurf analysis also offers numerous other functions, such as volume determination, calculation of isotropy or particle analysis. 

The software includes all DIN EN ISO standardized 2D parameters and a wealth of international characteristic values.
