Product Description
The Candela 7100 series advanced defect detection and classification system is designed specifically for analyzing HDD substrates and media. This HDD analyzer high-powered dual-wavelength laser is optimized for current defect of interest (DOI) challenges, and multi-channel scatter detectors provide enhanced sensitivity for classification of sub-micron pits, bumps, particles, and buried defects on a full range of substrates. The capability and stability of the 7100 series defect inspector ensures that one platform can be used for multiple process control application points, reducing dependency on tools and methods such as atomic force, scanning electron, and transmission electron microscopes to investigate defects and identify root cause.
Features
- Detects, classifies, and analyzes HDD sub-micron pits, bumps, particles, buried defects on metal and glass, substrates and media with full disk defect maps
- Provides faster time to results through full disk maps, with classified defects and actionable data output
- Reduces dependence on off-line inspection technologies (AFM, SEM, TEM, etc.) resulting in reduced overall cost of ownership
- Available in either a manual (7110) or fully-automated (7140) configuration
