Tiger-UT200 is a lego-style Spetrocphotometer/Spectrometer complete assembly kit, covering 200nm ~ 1050nm. It contains light sources, grating, slit, CCD detector, and all necessary opto-mechanical parts. Using the light sources, the optical density (absorption spectrum of molecules in 200-1050nm) can be measured. Without using the light source, it can be used as a spectrometer to obtain spectrum of 200-1050nm light source or fluorescence. The CCD detector used is Tiger-100. Following the instruction in manual, one should be able to easily assemble the components into a functioning device with a resolution better than 0.3nm. A pre-assembled version is also available upon request. This product is applicable to teaching, research, and fun play.
