The Harrick Praying Mantis™ Diffuse Reflection Accessory is a pioneering diffuse reflectance (DRIFTS) attachment designed for efficient collection and analysis of solid and powder samples. It incorporates 6:1, 90° off-axis ellipsoids that pivot for easy sampling area access and effectively minimize specular reflection interference by deflecting it away from the collecting ellipsoid.
This accessory supports controlled environment studies by allowing integration with optional reaction chambers suitable for FT-IR and UV-VIS spectroscopy. Typical applications include catalyst analysis under varied temperature and pressure, enabling reliable diffuse reflection measurements in both spectral ranges.
