The da vinci:Arm from Harrick Scientific is an articulated opto-mechanical FT-IR accessory designed for analysing samples that are too large to fit into the sample compartment of a spectrometer. The da Vinci Arm enables the analyses of samples by specular, diffuse and ATR reflection techniques. Since the da Vinci Arm is articulated, it simplifies analysis of samples in front of, below or above the spectrometer sample compartment. An integral camera provides for magnified viewing and image capture of the sampled spot.
