Pike Technologies have introduced the IRIS diamond ATR accessory. The backbone of the IRIS is its optics: powered mirrors have been designed and processed using diamond-turning technology. All mirrors are gold-coated for maximum reflectivity. The small monolithic diamond, less than 2 mm diameter, provides access to the full mid-IR spectral range. The diamond plate’s PTFE gasket seals between the diamond and the plate allowing the IRIS to be used for the analysis of strong organic solvents and caustic samples due to the inertness of PTFE. An optional Ge ATR crystal is available for high refractive index samples as are additional flow-through attachment and liquids retainer sampling tools.
