Technological Innovation

The core technolgoy of IRUBIS is the microstructured silicon crystal, an innovative sample carrier for ATR FTIR Spectroscopy.

During the manufacturing process, our sample carriers receive a special MEMS (Microelectromechanical Sturcturing) on the underside. The basic principle is based on the publication of Schumacher et al..

While other sample carriers for infrared spectroscopy are usually made of diamonds, the IRUBIS crystals are manufactured of silicon wafers. Therefore, they only cost a fraction while achieving the same high quality results.

The crystals can be purchased separately, we also offer special accessories that are suitable for all standard spectrometers.

In a nutshell: What is ATR infrared spectroscopy?

Infrared spectroscopy uses infrared light (heat radiation) to identify a large number of chemical substances like fluids, solids or gases. ATR stands for attenuated total reflection and is the method of choice for almost all routine analyses of fluids and solids.

In ATR infrared spectroscopy, an infrared light is pointed from below on a crystal, an infrared transparent prism. The light is almost totally reflected on the top surface, but a small part of the energy gets absorbed by the interaction with the molecules in the sample.

This loss of energy is measured and results in a spectrum which contains information about the sample.


We took the MEMS technology to the next level and improved it with our patent-panding signal enhancement technology. In addition to the microstructures on the underside, we also added them to the crystal surface. This leads to higher peaks in the spectrum.

We are also currently working on the integration of our crystals into microplates. The goal is to create an automated microplate reader.
