Flat Tip Diamond ATR-Fiber Touch Probe


Flat Tip Diamond ATR “Touch Probe” is suitable for touch measurements of solids as well as fluids with easy cleaning thanks to the probe design.

The flat tip ATR crystal design allows touch measurement of sensitive samples and soft solids like skin, resin or polymers without damaging them. Additionally, sticky and otherwise messy samples like syrups, glues or pastes can be easily cleaned off of the probe’s ATR crystal thanks to the flat shape. Comparison of conical and flat tip ATR probes shows that the flat tip probe allows the user to achieve a stable, constant surface area with solid and soft-solid samples. This ensures reliable and reproducible measurement results, giving the user quantitative data on the sample at hand.
