UVEX spectrograph

Categories: ,

UVEX is a cross Czerny-Turner  spectrograph optimized for wavelengths from near UV (<400nm) to near IR (1µm).

Your UVEX order will be shipped during June 2021.

In this article you will find a lot of additional information about UVEX.

It’s particularly dedicated to be used on Ritchey-Chretien type telescopes with a diameter up to 12 or 14 inches (at F/8)

The settings are precise and easily accessible:

  • A multi-turn knob adjusts the focus of the M2 internal mirror precisely.
  • An index os used to adjust the wavelength center of the spectrum on the camera sensor. A vernier (available for each type of grating) makes it possible to precisely position the grating at the desired wavelength.

The UVEX is delivered with a 600 gr/mm grating blazed at 500nm as well as adapter ring for ZWO cameras (others rings for QHY and ATIK cameras are also available in option).

The spectrograph slit has 5 positions that can be easily changed using a Phillips screwdriver (supplied with the UVEX). The slit position are for 25 µm, 50 µm, 100µm, 300 µm and a hole of 25µm. Other slits are available as an option and Alpy slits are compatible with UVEX.

A carrying case shockproof is delivered with the UVEX. It has pre-cut locations to safely transport the spectrograph with its camera as well as various accessories (additional networks, order filter, tools, etc..)

 

The UVEX is delivered with:

 

  • A 600 gr/mm grating blazed at 500nm
