摘要

The sample measurement unit (1), for an infra red spectrometer, has a diamond attenuated total reflectance (ATR) crystal (3). The ATR crystal has a flat or convex surface (5) and a second opposing surface (11) with a saw tooth structure (13) in one direction (x), without varying in a direction (y) at right angles.
