ATR Crystal

The basic version of our crystal has the same performance as a single bounce diamond crystal and a broad spectral range. The short optical path makes the fingerprint region accessible.

This crystal has a high angle of incidence and thus a reduced penetration depth. This version is suitable for various applications such as Surface Enhanced Infrared Absorption Spectroscopy (SEIRAS).

The patent-pending microstructures on the surface of this crystal lead to a better signal-to-noise ratio and enhance the IR signal. The result is a higher absorption and thus more distinct peaks.
