A compact reflectance-based TFM system for thickness measurement on wafer, glass, polymer, and coating samples.

Core strengths for this TFM system.
Standard, NIR, and XT options support thin-film and transparent µm-range applications.
Create a recipe from a simple sample-stack setup, save it, and reuse it for routine sample checks.
Designed so users can start practical thickness measurements without deep optical-modeling experience.
A compact manual-stage TFM system for wafer, glass, polymer, coating, and feasibility-test samples.
