Shelyak Full Eshel II System (ES0006)

• echelle spectroscope R>10000 (including 85mm f/1.8 lens)
• Fibre Injection & Guiding Unit F/6
• Object fibre 50µm, 20m length
• Calibration fibre 200µm, 20m length
• Thorium-Argon calibration unit
• cables and power supplies for standard european main supply (220V). To be adapted for other networks.

eShel II spectroscope PF0011

Choice of optical fibre has been made to increase radial velocities measurement accuracy and for a better confort in using the eShel. More details here.

eShel Calibration unit PF0012

It delivers the various sources of light to calibrate the spectrum :

• Thorium-Argon lamp with high voltage power supply for precise calibration
• Flat lamp for echelle order geometry and blaze processing

Fiber Injection and Guiding Unit F/6 PF0008

It makes it possible to inject the flux of the target into the optical fiber of the eShel. An autoguiding camera (not included) provides centering of the target and autoguiding on the input of the 50 μm optical fiber. It is also possible to inject the calibration lamps coming from the calibration module with a 200 μm optical fiber also connected to the injection unit. A remotely controllable mirror makes it possible to swich from one source to another. (F/9 on demand)

Variable T adapter BA0027 to mount your eShel fibre injection system on a Schmidt-Cassegrain Telescope (typically with a 0.63x focal reducer).
