Technical Specifications
-
echelle spectroscope R>10000Â (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

-
In the Box
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.
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).
Object optical fibre PF0051 (core diameter: 50µm) length 20 meters
Calibration optical fibre OP0024 (core diameter: 200µm) length 20 meters
Manual & Warranty
You can see user guide and set up guide for this system.
Software to remote control the calibration unit in RS 232
