The UVEX is the most versatile instrument in our product range. Achromatic by design, it can explore far into the ultraviolet and infrared – at the very limits of what today’s cameras can achieve. The interchangeable grating allows different resolutions. Combined with its motorization module, it can be operated remotely.

Order filter |
The order filter is recommended for observations in the IR: it avoids order overlap (the second order of the blue part of the spectrum is superimposed on the first order of the IR). |

Eypiece holder for the UVEX It complements the guiding module and allows guiding by eye, rather than by camera. For 1,25″ eyepiece (not supplied). |
We recommend using the ZWO ASI533 MM Pro camera with the UVEX spectrograph.
In this article you will find a lot of additional information about UVEX.
It is particularly suitable for Ritchey-Chretien (RC) telescopes up to 400mm in diameter (F/8).
Settings are precise and easily accessible:
The uvex is supplied with a 600 tr/mm grating blazed at 500nm and an adapter ring for ZWO cameras (other rings for QHY and ATIK cameras are also available as options).
The UVEX spectroscope slit has 6 positions that can be easily changed using a Phillips screwdriver (supplied with the UVEX). Several slit widths are available: 25µm, 50µm, 100µm, 300µm, a 25µm hole and a 3mm hole. Other slits are available as an option and Alpy slits are compatible with UVEX.
A shockproof case is supplied with UVEX. It includes pre-cut slots for safely transporting the spectrograph with its camera, as well as various accessories (additional networks, order filter, tools, etc.).

When looking to upgrade from my LISA in 2020, the UVEX had much to recommend it. Its ability to access a broad spectral range was important as was the flexibility to both adjust the grating angle and to swap over gratings to shift between low and mid resolution....
UVEX is a multi purpose spectrograph allowing spectra to be performed in the near IR and near UV domains but also on weak targets.
