Spectrometers and Accessories

The USB2000/USB4000 spectrometers are  miniature fiber optic UV-VIS-NIR detection systems for low light level applications.  They are compact and portable, measuring just 63.34 mm x 89.10 mm x 34.37 mm, and weighing only 180 g. These spectrometers accept light energy transmitted through single-strand optical fiber and disperses it via a fixed grating across the CCD array.   These spectrometers are compatible with all of our FIA/SIA systems.

FIAlab offers three configurations as listed below.  Custom and Multiple channel configurations are also available, please inquire.   For accessories such as flowcells, light sources, and optical cables,  visit our spectrometer accessories page.

USB4000 UV-VIS for Colorimetric assays between 200 and 850 nm.
 USB4000 VIS-NIR for Colorimetric assays between 350 and 1000 nm.
 USB2000 VIS-NIR-FL for Fluorometric assays between 350 and 1000 nm

The USB4000-UV-VIS Spectrometer is pre-set to a 200-850 nm wavelength range and comes with a UV2 Detector Upgrade, a multi-bandpass order-sorting detector coating and a 25 mm entrance slit for optical resolution to 1.5 nm (FWHM). Operating software is included.
