Flexible Hardware & Software Options
In research, it is often unpredictable as to what type of surface will need to be measured. With this in mind, the Zeta-300 offers a modular design that allows for a wider range of hardware measurement options as well as software packages:
- Piezo stage for 3 nm z-resolution
- Automatic feature detect/measure software
- Automatic surface area calculation, statistical analysis
- Bright-field and Interferometric objectives
- DIC/Nomarski for nanometer-scale roughness
- Tilt stages, sample holders and vacuum chucks
User Testimonial
The diversity and speed of the KLA Instruments Zeta-300 are unmatched qualities of this system that make it indispensable in the lab. The customer service is fast and helped us even with the most unique and special requests we had, including personal software updates.
