TVSPEC allows you to display visible spectra on your PC. Simply connect TVSPEC to a USB port of your PC, point the spectrometer at a source of light, and observe both spectral image and intensity graph live on your PC monitor.
Each TVSPEC has a calibration file, which allows the spectra to be displayed directly in wavelength (nm).
Mono CCD, but with colour display - excellent for measurement. Wavelength range 300~800nm, resolution <3nm at 500nm

TVSPEC-USB employs a colour CCD and is very good for demonstration purposes giving a realtime colour display.
Good for use with emission line spectra, but because of the RGB pixels, does not give an accurate representation of continuous spectra such as Black Bodies, where TVSPEC is ideal.
Wavelength range 300~800nm, resolution <3nm at 500nm.

CCDSPEC is an integrating CCD imaging spectrograph which has both laboratory and astronomical options. In the astronomical version the slit has a central aperture to allow acquisition and for slitless spectroscopy.
With the Meade DSI I CCD, the spectral range is 380nm-680 nm with a resolution of <3nm at 500nm.

SolarP is an experiment which allows students to determine the Solar Power received at the Earth’s surface. If we correct for the absorbtion in the Earth’s atmosphere we can determine the power per unit area above the Earth’s atmosphere and this is known as the “Solar Constant”. This leads to the Solar Luminosity in Watts and then using E=mc² we can calculate the rate of conversion of mass to energy and the lifetime of the Sun.
