How it works
An optical or metrology component supports imaging, measurement, alignment, or light-based inspection functions.
Optical alignment, wavelength compatibility, calibration state, and cleanliness can be essential to measurement accuracy.
Technical guide
common
May include optical glass, sapphire, lenses, mirrors, mounts, or precision electronics.
optical measurement
Uses light, imaging, or interferometry-style measurement hardware.
What to verify before purchase
- Verify wafer condition, coating/emissivity surface, serial/lot, and whether it is intact and cleanroom-packaged.
Confirm with the seller
- Exact emissivity value and calibration status are not confirmed.
