The Raman spectrometers of our partner Wasatch Photonic are characterized by their sensitivity, low noise and compact design. Thanks to the optical design based on the proprietary VPH transmission grating and f/1.3 optics, these spectrometers offer 10 times the sensitivity and 10 times the SNR of comparable compact spectrometers.

To meet the various requirements from research, industry and OEM, our partner Wasatch Photonics offers Raman spectrometers as modular systems as well as semi-integrated and fully integrated systems.

A modular Raman system uses fibers to pass excitation light between the laser, probe and spectrometer. This physically flexible interface is well suited for bringing Raman to the sample (clinical use, art analysis, in-situ process monitoring), or when the spectrometer cannot get too close to the sample (production line or extreme environments). It also offers maximum reconfigurability to mix and match components as desired, change sampling accessories, or reuse existing equipment.

A semi-integrated Raman system combines the spectrometer and laser into a single unit to reduce space requirements and cost, while separate connectors for each allow for a fiber-optic Raman probe or other sampling optics. This configuration maximizes value without sacrificing flexibility and provides signals comparable to a fully modular system. Power and control of the laser are provided through the spectrometer, simplifying cabling and enabling remote/automated operation.

A fully integrated Raman system combines the laser, sampling optics and spectrometer into a single unit, eliminating fibers that can cause additional coupling losses and breakage. Communications and power are also combined in a single, compact package with direct laser power control through software or drivers. A fully integrated system delivers a much higher signal thanks to the integrated optics, while a modular system offers more flexibility.
