UVEX Spectroscope
5 389,20 € incl. VAT - 4 491,00 € excl. VAT
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.

All about the UVEX spectroscope :
Description
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:
- A multi-turn knob adjusts the focus of the M2 internal mirror.
- Use the index to set the central wavelength of the spectrum on the camera sensor. A vernier (available for each type of grating) allows you to position the grating precisely at the desired wavelength.
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.).

Remote Spectroscopy – the UVEX Motor Unit
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 : Extreme spectra
UVEX is a multi purpose spectrograph allowing spectra to be performed in the near IR and near UV domains but also on weak targets.
