Overview
This spectrometer is a uniquely designed, single photon response level ultra high sensitivity miniature spectrometer. Due to its polarized optical design, unlike traditional grating spectrometers, it does not require slits or fibers, making it have a large light receiving area. Therefore, this ultra-high sensitivity spectrometer is an ideal choice for low light measurement and can be used for fluorescence spectroscopy, diffuse reflectance spectroscopy, and Raman spectroscopy analysis.

Ultra high sensitivity miniature spectrometerFeatures: This spectrometer is uniquely designed with a single photon response levelUltra high sensitivity miniature spectrometerDue to its polarized optical design, unlike traditional grating spectrometers, it does not require slits or fibers, making it have a large light receiving area. Therefore, thisUltra high sensitivity spectrometerIt is an ideal choice for low light measurement and can be used for fluorescence spectroscopy, diffuse reflectance spectroscopy,Raman spectroscopy analysis.
ARCspectro HT is ideal for low light applications or for the spectral analysis of diffusing light sources (or samples). Its unique design permits togather a maximum of lightover a large diffusing surface (several millimeters!) and over a large angle (±10°). This gives atremendous throughput advantage(~50x more) compared to the most powerful grating spectrometers(also well-known Jaquinot advantage) which are intrinsically limited by a small entrance slit (typically 0.025mm).This makes this unique device ideal for applications were small light intensities has to be analyzed (fluorescence or Raman spectroscopy).
