Microstructured Bottom and Single Reflection
During the manufacturing process, our crystals receive a special MEMS (Microelectromechanical Structuring) on the underside. This makes them an ideal IRE (Internal Reflection Element) for Single Reflection ATR.
In comparism to Multi-Bounce ATR, where multiple internal reflections occur, the microstructures serve as individual prisms in which single internal reflections occur.
The advantage compared to other Single-Bounce ATRs is the large coupling area. The light can be coupled into each of the single prisms, so exact positioning is not necessary.
