Zeta-20 True Color 3D Optical Profiler
The Zeta-20TM is a fully-integrated optical profilometer that provides advanced 3D imaging and metrology features in a flexible, cost-effective package. Zeta's proprietary Z-DotTM technology enables rapid surface measurement of PSS, Solar Cells, Fluid Microchannels, and other surfaces that more costly systems cannot easily handle.
The Zeta-200TM advanced optical profilometer provides automated 3D imaging and metrology capabilities in a flexible, cost-effective package. Zeta Instruments’ proprietary focus map technology enables rapid, true-color imaging and surface measurement of surfaces for off-line product inspection. The Zeta 200 automatically gathers data on step height, feature volume, dimensions and roughness on multiple measurement sites to give you the data you need to monitor and optimize your manufacturing processes.

The ZetaScan-Series are fully automated 300mm capable defect inspection tool that can address a variety of substrates such as rough ground substrates, polished and unpolished, opaque and transparent wafers as well as touch panels. Based on Zeta’s revolutionary multi-mode approach to inspection, the ZetaScan-series defect inspectors provide high defect sensitivity at high throughput.
ZetaScan-Series Automated Substrate Defect Inspection
The Zeta-300 provides integral acoustic isolation to reduce the effects of sound and air currents on sample measurements.  When gathering data on structures that are less than 1µm high, even small vibrations caused by sound and air disturbances can affect your results.  Coupled with an optional isolation table, the Zeta-300 delivers accuracy and repeatability unmatched by other optical profilers.
