Elliott Instruments CCDSPEC has been specially designed for amateur astronomers and small

observatories, to take scientifically useful spectra of astronomical objects from stars and nebulae, to

the red-shifts of galaxies and supernovae.

 It has slit viewing optics to allow guiding of stars on the slit for long exposures of faint objects. Most CCD cameras will fit CCDSPEC.

Available without a CCD camera for those who have their own, or can be supplied with a QHY6

CCD camera, pre-focussed and fully wavelength calibrated.



This is a laboratory spectrometer for either real time operation or long exposure for faint sources using a cooled CCD detector

The real time spectrometer uses Point Grey CMOS cameras. Simply connect DigiSpec  to a USB port of your PC, point the spectrometer at a source of light, and observe both a real time spectrum image and intensity graph live on your PC monitor

The cooled integrating spectrometer uses a QHY6 CCD camera and has no real time display, but the  integrated data is saved and then displayed

The 16 bit digital spectrum is displayed directly in wavelength (nm) in the range 350-750nm with a wavelength resolution ~1.5nm at 500nm.



is an experiment which allows students to determine the Solar Power received at the Earth’s surface.

If we correct for the absorption 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 Watt.

Using E=mc2 we can calculate the rate of conversion of mass to energy and the lifetime of the Sun.

Suitable for all levels of study from School to University students.
