Aurora 4000 High-Resolution Fibre-Optic Spectrometer

A 3648-pixel linear-CCD spectrometer on a 101.6 mm crossed Czerny-Turner bench. With a narrow grating range and a 10 µm entrance aperture it resolves 0.08 nm; the standard 200–1100 nm configuration gives 0.75 nm. Wavelength range and resolution are configured to order.
