Through Transmissive Media
Enables high-resolution measurements through protective packaging, environmental chambers and other dispersive materials
Key features of Bruker's TTM Module
- Measure samples through glass and other materials up to 3mm thick
- Innovative illumination enables up to 40x measurements
- Universal housing supports multiple magnifications and compensation materials
- 20x objective offers 25:1 aspect ratio for deep trench measurements
- For MEMS, materials science, biological applications, and more
The R&D 100 award winning TTM module is available with three objectives 2x, 10x, and 20x for magnifications from 1x to 40x. Simple manual exchange of glass slides makes the module flexible for materials of varied thicknesses.

How does it work?
To compensate for interference fringes caused by the transparent films or packaging materials a glass of equal material and thickness is inserted between the beamsplitter and reference mirror (light blue box). Thus effectively canceling out any interference resulting from the device's packaging material.
