TFM-Contact

Contact-style probe system for coated parts

A contact-style TFM package for large, curved, or installed coated parts where the probe moves to the part.

Key Benefits

Core strengths for this TFM system.

01

Hand-held contact probe

Moves the probe to the part instead of forcing the part onto a fixed sample stage.

02

Curved and large parts

Practical for optical covers, lenses, anti-fog coatings, automotive hardcoat, and coated plastic components.

03

TFM workflow for contact checks

Uses the same recipe-based measurement concept as TFM-100 for repeated coating checks.

04

Flexible probe options

Supports standard or long-range reflectance probe options for different installation needs.
