IsoPlane SCT-320 imaging spectrograph

Share this on social media:

Princeton Instruments has released its imaging spectrograph, the IsoPlane SCT-320. The IsoPlane features a new optical design that eliminates the primary aberrations present in traditional imaging spectrographs. It produces clear images that are sharp across the focal plane. As a result, more photons end up in spectral peaks, significantly increasing the effective signal-to-noise ratio (SNR).

The system greatly reduces coma aberrations, thus preserving spectral resolution at all wavelengths. Astigmatism is also completely eliminated in the spectrograph, which means many more fibres in a bundle can be resolved, eliminating crosstalk in multichannel spectroscopy.

Applications for the IsoPlane spectrograph include multichannel spectroscopy, microspectroscopy, Raman scattering, fluorescence, photoluminescence, laser-induced breakdown spectroscopy (LIBS), Fourier-domain spectroscopy, biomedical imaging, and most other spectroscopic imaging techniques.
