Horiba Scientific has introduced the Lumetta fixed grating F/2 spectrograph. It is designed to optimally gather light from most fibres and high-angle scattering phenomena. Being an imaging spectrograph, it also enables such techniques as multitrack spectroscopy and fast hyperspectral imaging. With multitrack spectroscopy, multiple independent spectroscopy channels can be measured, 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. It has a scientific Grade 1 CCD deep cooled to –50 °C together with low-noise, 16-bit electronics and signal-to-noise ratio of 1200 : 1. Lumetta also has a flexible signal input interface, accommodating free-space as well as FC, SMA and ferrule fibre interfaces. Furthermore, spectral resolution can be controlled from a selection of interchangeable slits.
