StellarNets’ UVN-SR fiber optic spectrometer covers the 200-1100nm wavelength range and easily performs a variety of spectroscopy measurements with the SpectraWiz software. The optics utilize a UV enhanced CCD or PDA detector array configured with eXtreme grating technology to deliver high efficiency in both UV & NIR spectral extremes. The eXtreme optics include an integrated multi-band order sorting filter and UV enhanced detector array with optical lens to provide maximum sensitivity. The UVN-SR can be optionally calibrated for use as a SpectroRadiometer when precision measurement of light color and absolute intensity is needed. A 25um slit or larger is recommended for best spectroradiometric performance coupled with a 1000um core diameter fiber input (via standard SMA 905 connector).
