THE Q UESTAR® _QMAXTM _ Spectrometer

Highest wavelength resolution - to 0.017 nanometers - of any visual
spectrometer in the world, relative to its size. Attached to a QUESTAR ®
the patented QMAXTM delivers the finest, combined spacial plus
wavelength resolution of solar, Fraunhofer lines, natural broadening,
sunspot spectra, strong zeeman splitting, the helium discovery line,
and prominence and flare emission achievable in a compact package.
Linked to a webcam, the QMAXTM helps you to demonstrate the
explanatory power of the quantum mechanics, from the Bohr atom to
the Heisenberg Uncertainly Principle, to a large audience.
