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 scientifical tool to study faint objects (novae, variable stars, comets, asteroids, nebulae, galaxies, quasars...), to monitor group of stars, to analyse chemicaly planets in visible or near infra-red domain, etc...


Shelyak LISA Near IR Spectrograph

Do you want to study and analyze celestial objects by examining their spectra? The Shelyak LISA spectrograph is the perfect scientific and educational tool to delve into the fascinating and illuminating world of NIR spectrography. The LISA is a low resolution, high luminosity spectrograph that is capable of studying faint objects, including variable stars, asteroids, comets, novae, nebulae, galaxies, and quasar. It also allows chemical analysis of the planets in near infrared.


This model of the LISA comes with a slit for studying objects in the NIR domain of 650 - 1000nm. The included slit has four positions: 15, 19, 23 & 35um. Additional slits are available optionally.

The Shelyak LISA front plate comes with a standard T-mount thread . Backfocus is 41 mm  measured from the top of the flat face of the instrument to the slit position.
