Maximum throughput with a small block size chassis.
The Stroker f/1.3 Raman Spectrometer series achieves the highest throughput among all miniature spectrometers on the market. The design starts with a high-efficiency HD volume phase holographic grating that provides maximum diffraction efficiency and extremely low stray light. At this f/#, a custom lens design with the correct AR coating is required for excellent image quality and high transmittance. Low-noise electronics that make up the system are used in the back-illuminated silicon array. The final step was to use a high NA fiber power converter to effectively couple all the light sampled from the laser spot into the slit. With this type of signal enhancement, TE cooling of the detector is no longer necessary. The integration time is very short, allowing low-power lasers to be used to obtain high SNR Raman spectra.

Applications/Examples of results
The unique f/1.3 Raman spectrometer design from Wasatch Photonics allows for sample collection in milliseconds, compared to competitors' spectrometers that take several seconds for measurements. One of the most important factors for Wasatch is the low f#. The f# describes the throughput of the spectrometer. A low f# means a larger collection angle, which in turn allows more Raman scattered light to be illuminated on the slit. As the signal increases, the integration time decreases. This enables 19 times more integration compared to competitors' spectrometers.
