Bruker Optics Inc. is offering the IRcube high-performance interferometer for mid-infrared spectroscopy. The device has a small footprint – 11.5 × 12.5 × 9 in. – and permanently aligned optics that make it insensitive to vibrations and temperature changes. It features a developer's tool kit and ActiveX controls that allow programming with VB scripts. The IRcube can be used as a UHV chamber-coupling module, as a reflectance module or as a gas analyzer. Adaptable focal length optics make it suitable for applications in reflectance mode, including determination of layer thickness on metals or semiconductors and identification of minerals and ceramics.
