UV/vis spectrophotometer StellarNet

StellarNet provides both low cost and research grade UV-VIS spectrometers for routine and at line process measurement of sample absorbance, transmittance, and reflectance. The spectrometer wavelength range covers 200-850nm or 190-790nm depending on the model selected. The units incorporate UV enhanced CCD detectors with multi band coatings to minimize second order wavelength detection. 25um slits are permanently installed to set resolution at 0.85nm across their UV VIS operating range. The optics incorporate a 40mm diameter concave grating that produces an aberration corrected, flat field onto the detector. Without mirrors, the grating provides superb image quality and maintains low stray light.
