Raman scattering is a weak signal. Wasatch Photonics achieves exceptional Raman sensitivity through system-level optical optimization. A Wasatch Photonics Raman system is designed, from the sample objective lens to the detector, for highest efficiency, generating and collecting as many photons as possible from the sample, and losing as few as possible on their way to being turned into an electronic signal.
Low f/number Design
The f/# quantifies the light-gathering ability of an optical system and captures how efficiently a spectrometer collects light. The f/1.3 optical bench design Wasatch is known for maximizes throughput, making it an excellent choice for Raman applications requiring strong signal and short acquisition times.
High-efficiency Gratings
High-efficiency holographic gratings are used in the low f/# bench design to maximize light collection and throughput. Grating designs are individually optimized for each spectrometer’s range and laser wavelength, to deliver smooth, and exceptionally high, first-order diffraction efficiency with very low polarization sensitivity across the full spectral range.
System Level Optimization
Equally important to the bench itself, the Raman probe is matched to the spectrometer optics and equipped with high-performance filter sets, ensuring efficient signal delivery with strong laser rejection. Excellent Raman sensitivity.
Excellent Raman sensitivity
This careful design enables rapid measurements and lower detection limits, even for weak Raman emitters.
