 Cameras for Spectroscope UVEX & LISA (VIS)

UVEX motorized Spectroscope

UVEX 2The UVEX is the most versatile instrument in the 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 gratings (in option) allow different resolutions. Combined with its motorization module, it can be operated remotely.

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 (equivalent to the SPOX module). So it’s easy to do your dark, flats and calibration images remotely.

The UVEX is now motorized, and can be operated remotely.

The spectrograph slit has 6 positions that can be easily changed using a Phillips screwdriver (supplied with the UVEX). Several slot widths are available: 25µm, 50µm, 100µm, 300µm, a 25µm hole and a 3mm hole. Other slots are available as options, and Alpy slots are UVEX-compatible.

Mototrization :
The motorized UVEX allows you to select the central wavelength observed (grating angle) and adjust the spectroscope’s focus.

Remote control of integrated calibration module :
The motorization integrates the control of the calibration module (equivalent to the SPOX module). It is therefore easy to make your images of black, flats and calibration, remotely.

UVEX 3DEMETRA remote control Version:
The UVEX motorization module is accompanied by a new version of the DEMETRA software:
– Calibration “by set line”. We establish once and for all the law of dispersion, and we can readjust it on a well identified line. This is useful for covering all areas from UV to IR, when the reference lines are few.
– Motors module control,
– Image sequences, to link several series of images,
– Consideration of CMOS cameras (by the CMED correction step).

Not a DEMETRA user? Don’t panic, Shelyak has thought of you!
We provide you with a small software program, USIS Controller, which allows you to control the UVEX from your computer: USIS-controller
And if you want to integrate UVEX control more deeply into your own environment, the communication protocol between the computer and the UVEX motorization module is documented: this is the USIS protocol.

Camera recommendation

The acquisition camera (or “Science” camera) is used to acquire the spectra of the observed object. The criteria for choosing a camera are :

The size of the sensor (the bigger the better)
The size of the pixels (which gives the sampling)
Reading dynamics (the number of shades the camera can see)
Quantum efficiency (the sensitivity of the camera to light)
Reading noise (the lower the better)
Cooling (for long exposures)

In each product sheet you will find the camera we recommend – but of course other solutions are possible.
