The Raspberry Spegg UVVIS29 in aluminum housing is equipped with two broadband LEDs (blueUVA-B and Gold LED). Both LEDs can be controlled independently and together in intensity and cover a spectral range from 270nm to 1050nm.
Both broadband LEDs radiate through a common F-SMA 905 connector. Various optical fibers (see accessories) can be connected to this. The cuvette holder (see accessories) shown on the left can also be connected to the port. It can be used to measure standard cuvettes with 13mm edge length.
The optical fiber of the spectrometer is stably mounted in a gooseneck and has an M-SMA 905 connector. Spectra can be recorded from 0.2ms to several seconds over the spectral range from 250nm to 1050nm with various gains and a very good signal-to-noise ratio.
The demo software is written in Python and can be adapted to individual needs. Thus, various experimental sequences can be freely programmed. Absorption, transmission and the recording of external light sources with different filter options are possible with the demo software. The spectra can be displayed in 2D and 3D. A manual and automatic saving of the spectra e.g. in Excel csv file is possible.
