Industrial & Applied Science

The Thermo Scientific™ Imaging ATR Accessory provides enhanced spatial resolution and high speed data acquisition for FT-IR chemical imaging applications. The Thermo Scientific Imaging ATR accessory expands our portfolio of ATR products for Thermo Scientific Nicolet™ infrared microscopes with a tool uniquely suited to support chemical imaging studies with enhanced spatial resolution. Imaging a sample in contact with a germanium ATR crystal effectively improves the resolution by a factor of four. The Imaging ATR Accessory is a faster alternative to single point ATR mapping because only a single, large area, contact point is required. Coupling ATR with an infrared microscope creates a unique capability to explore the microscopic structure of heterogeneous samples. Observable features in specimens such as defects, particles, fibers or inks may be analyzed just by contacting the feature with the ATR crystal surface using guidance from microscope viewer.
