Since a probe starts to wear very quickly, solid diamond is more durable with respect to the application.  The solid diamond stylus should also be used to carry out discrete-point probing with high point loading.

The diamond-coated stylus is especially suitable for applications with components made of soft materials such as aluminum, titanium, or copper. There is no build-up of material on the diamond-coated ZEISSS Diamond!Scan stylus when aluminum parts are scanned. For measuring hard components made of ceramic or hard-coated surfaces, we recommend the use of a solid diamond stylus.

Another difference between diamond-coated spheres and solid diamond spheres is the roundness. 

Diamond-coated spheres have a roundness better than 150 μm (Grade 5).      On the other hand, the maximum roundness of solid diamond spheres is defined as 250 μm (Grade 10). The diameters for a solid diamond sphere are limited to 1, 2 and 3 mm. We  offer the coated diamond spheres in a larger range of variants ranging from 0.3 to 10 mm.

Advantages of solid diamond ZEISS Diamond!Scan styli:

• More robust with point loading

• High wear resistance on ceramic

• Roundness <250 μm (Grade 10)

• For universal use

Advantages of diamond-coated ZEISS Diamond!Scan styli:

• No build-up of material when scanning aluminum

• Roundness <150 μm (Grade 5)

• Various sphere diameters possible

• Less expensive
