At Wasatch Photonics we understand the difference that high sensitivity, low noise, and the ability to capture spectra quickly can make to a research project or OEM product design. Our f/1.3 spectrometers are designed specifically for Raman using our own patented VPH gratings, delivering 10x the sensitivity and SNR of a typical compact spectrometer.

What system type is best for my application – modular, semi-integrated, or fully integrated?

The choice between a flexible, probe-based Raman system and a fully integrated, compact one depends largely upon which optical coupling method is best for your application or sample. Sensitivity, size, and laser control may also be considered.

A modular Raman system uses fibers to route excitation light between laser, probe, and spectrometer. This physically flexible interface is good for bringing Raman to the sample (clinical use, art analysis, in-situ process monitoring), or when the spectrometer can’t 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 accessory, or to re-use existing equipment.

A semi-integrated Raman system combines the spectrometer and laser into a single unit to reduce footprint and cost, while separate connectors for each allow a fiber-optic Raman probe or other sampling optics to be used. This configuration maximizes value without sacrificing flexibility, and yields signal comparable to a fully modular system. Power and controls for the laser are provided through the spectrometer, simplifying cabling and allowing remote/automated operation.

A fully integrated Raman system brings the laser, sampling optics, and spectrometer together into one unit, eliminating fibers which add coupling losses and can break. Communications and power supply are also consolidated into a single, compact footprint with direct laser power control through software or drivers. A fully integrated system delivers considerably higher signal thanks to the integrated optics, while a modular system offers more flexibility.
