eShel spectroscope

The eShel spectroscope is a professional-level multi-order (Echelle grating) fiber-fed instrument.

It combines high resolution (R = 10,000) with a wide spectral range (from 390 to 750nm) – for example, to study exoplanets.

The eShel spectroscope needs to be completed with a FIGU, a calibration module and optical fibers for operation. The “complete eShel system” (ES0006) contains all these elements.
