Shelyak LISA VISUAL Slit Spectrograph
LISA is a low resolution high luminosity spectrograph F/5, R~600-1000. This is the basic module for observations in the VISIBLE SPECTRUM between 400 and 700nm.
LISA is also available in near Infra-Red version.
Explore to the limit of your telescope with our LISA low resolution high luminosity spectrograph. With its slit, LISA is specially designed for faint or extended objects.
It is an educational tool for student to quickly record spectra of stars and nebulae and focus on actual project rather than long observing hours.
It is also a scientific tool to study faint objects (variable stars, novae, nebulae, comets, quasars, asteroids, galaxies, etc.), to monitor group of stars, to analyse chemical properties of planets in the visible or near infra-red spectrum, etc...
