Ondax manufactures optical filters with edges that are 10 times steeper than the so called razorsharp edges of the best dielectric raman filters. Ondax also integrates the volume holographic filters into diode laser in order to stabilize the wavelength narrowing the linewidth to typically <100MHz. Using these filters measurements of raman scattering can be performed enabling the precise characterization of chemical components.
Ondax’s patented THz-Raman® Spectroscopy Modules extend the range of traditional Raman spectroscopy into the terahertz/low-frequency regime, exploring the same range of energy transitions as terahertz spectroscopy – without limiting the ability to measure the fingerprint region. This region reveals a new “Structural Fingerprint” to complement the traditional “Chemical Fingerprint” of Raman, enabling simultaneous analysis of both molecular structure and chemical composition in one instrument for advanced materials characterization.
The TR-PROBE is a compact, robust THz-Raman probe thatenables in-situ reaction or process monitoring, which can beflexibly configured with a variety of sample interface accessories,including immersion/contact probe tips, a vial/tabletholder, a transmission Raman adapter, a microscope mount,or a steerable non-contact optic. A separate CleanLine™ diode laser or DPSS/OPSL laser provides ASE-free excitation via a fiber optic coupling,enabling the probe to operate in harsher environments where electrical connections are not permitted. The athermaldesign allows usage over a wide range of operating temperatureenvironments. The symmetry of the Stokes/anti-Stokes signals provides a spectral calibration reference in every measurement. This compact yet rugged design enables both in-line reaction monitoring and off-line testing of material properties with no special sample preparation required.
