UVEX is a particularly versatile spectrograph. Thanks to its achromatic design, it can penetrate far into the ultraviolet and infrared range - to the limits of what today's cameras can achieve. The interchangeable grating enables different resolutions. In combination with its optional motorisation module, it can be operated remotely.
The UVEX is a "crossed" Czerny-Turner spectroscope that is optimised for wavelengths from the near UV range (<350 nm) to the near IR range (1 µm). We recommend using the ZWO Camera ASI 533 MM Pro Mono with the UVEX spectrograph.
It is particularly suitable for ritchey-chretien (RC) telescopes with an aperture of up to 400 mm (F/8).
The settings are precise and easily accessible: a multi-rotation knob adjusts the focus of the internal M2 mirrors. Use the index to set the centre wavelength of the spectrum on the camera sensor. A vernier (available for each grating type) allows you to precisely adjust the grating to the desired wavelength.
The UVEX is supplied with a 600 tr/mm grating 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 with a Phillips screwdriver (included with the UVEX). Several slit widths are available: 25 µm, 50 µm, 100 µm, 300 µm, a 25 µm aperture and a 3 mm aperture. Other gaps are optionally available (Alpy gaps are compatible with UVEX).
A shock-resistant case is included in the UVEX scope of delivery.
The motorized UVEX is the ultimate version of the UVEX, allowing remote operation. You can remotely control the central wavelength (grating angle) and adjust the spectroscope’s focus.
The motorization integrates the control of the calibration module. So it’s easy to do your dark, flats and calibration images remotely.
