HORIBA Scientific has announced a new look for its Lumetta fixed grating spectrograph. The new design houses an F/2 spectrograph with a large area sensor. It is designed to gather light from most fibres and high angle scattering phenomena. As an imaging spectrograph, it also enables advanced techniques such as multitrack spectroscopy and fast hyperspectral imaging. With multitrack spectroscopy, multiple independent spectroscopy channels can be measured with Lumetta, either improving sample measurement throughput for similar measurements on different samples, or simultaneous measurement of different but complementary spectra such as photoluminescence and absorbance from the same sample. A scientific grade I CCD deep cooled to –50 °C, together with low noise 16-bit electronics, produces a signal-to-noise ratio of 1200 : 1 and its deep cooling allows signal integration for hours. Lumetta also offers a flexible signal input interface, accommodating free-space as well as FC, SMA and ferrule fibre interfaces. Spectral resolution can be controlled from a selection of interchangeable slits.
