Harrick daVinci Arm Reflection Accessory



The da Vinci Arm is a unique articulated opto-mechanical FTIR accessory designed for analyzing samples that are too large to fit into the sample compartment of a spectrometer. The da Vinci Arm enables the analysis 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. The sampling surface can be facing in any direction – up, down, or sideways. Samples such as paintings, vases, sculptures, etc. can now be easily analyzed. The integral camera provides for magnified viewing and image capture of the sampled spot. The entire optical path of the IR beam is enclosed and integrated into the purge of the host spectrometer.

The da Vinci Arm is excellent for qualitative and quantitative analysis of samples that are too large to fit within the FTIR spectrometer sample compartment. Applications include analysis of neat samples or small spots on large samples via diffuse reflectance, specular reflectance or ATR spectroscopy.
