TVSPEC-USB
TVSPEC-USB allows you to
display
visible spectra on your PC.
Simply
connect TVSPEC to a USB port,
point the spectrometer at a source of light and observe its spectrum
in full colour live on the PC display. The spectrometer can be used to
demonstrate all
aspects of colour and spectra at all levels of science in Physics,
Astronomy, Chemistry
and Biology. Images are stored as bitmaps, and spectra can be exported
into spreadsheets for further analysis.
The colour display and image capture is provided by USBSpec
and custom designed software PCSpectraLite
allows display and analysis of saved
wavelength calibrated spectra.
Typical uses of TVSPEC-USB
This instrument is best suited for the colour display of spectra in
lectures and demonstrations
wheras the standard monochrome TVSPEC is to be prefered for accuarate
measurements, especially so when
continuous spectra are important.
Emission spectra
- line spectra of gases such as
Hydrogen,
Helium, Neon, mercury, and the new
energy saving fluorescent lamps.
Flame spectra used in Chemistry such as Na, K, Cu,Sr and modern light
sources such as LEDs and lasers.
Absorption spectra
- the Fraunhoher absorption
lines in the Sun are visible showing the presence of hydrogen and other
elements and
absorption of light by colour filters and biological pigments such as
Chrorophyll and Haemoglobin.
