CCD Spektrometer mit 650 aktiven Pixeln, 350 - 1000 nm

USB650 – low-cost training spectrometer

Request for information

Our USB650 spectrometer is a low-cost and small CCD spectrometer which is very well suited for trainings as well as for budget limited educational and research laboratories. It covers wavelengths of 350 up to 1000 nm using a CCD detector with 650 activated pixels. The spectrometer is set-up with a 25 µm input slit and therewith reaches optical resolutions of 2 nm (FWHM). Hence, it is applicable for various VIS applications.
The software Software SpectraSuite is already included in delivery.

Application: Transmission measurement at cuvettes within a spectral range of 350-900nm - USB650-CUV

ruggedized measurement system – no fiber optics needed
mobile system – power supply via USB of PC or laptop
application example: measurement of color changes, measurement of concentration using Lambert-Beer’s law

Application: Emission measurement – USB650-E

good price-performance ratio
easy handling
application example: comparison of light sources (e.g. fluorescent tube vs. light bulb), spectral analysis of sunlight

Application: Reflection measurement at solids – USB650-R

measuring diffuse or direct reflections using fiber optic probes
6 illumination fibers placed around the detection fiber
stainless steel measuring dip with a diameter of 6,35mm
application example: measurements at leaves, color determination at solids
