SECTION 1: INTRODUCTION
Thank you for choosing the Andor Mechelle, which offers several innovations to the spectroscopist. The Andor
Mechelle spectrograph is based on the echelle grating principal and has a patented optical design, which gives
extremely low cross-talk, equally spaced order separation and maximum resolution, compared with other spectrographs.
The Mechelle offers a simultaneously recorded wavelength range from UV to NIR with very high resolution and no
overlapping wavelengths.
• The Mechelle features patented, corrected off-axis optics enabling the user to achieve maximum throughput
and optimum Gaussian line shape and resolution. This translates to a wide wavelength range from the deep
UV through to NIR, with full spectral continuity, no gaps and no overlapping wavelengths. You get the whole
spectrum in one single acquisition. The maximum wavelength range is set by the detector sensitivity and the
low wavelength limit is set by the absorption of air.
• The spectrograph has a rugged compact design with no moving parts, enabling the Mechelle spectrograph
to withstand more physical handling than other high performance spectrographs. This makes the Mechelle an
ideal spectrograph for OEMs and non-lab based applications, from zero gravity experiments to operation in high
temperature environments. The unit can also be evacuated for working in the deep UV.
• Andor have utilised many years experience in spectroscopy to deliver a software platform designed for
spectroscopists. The Solis software allows direct control over spectrograph functionally. A user-friendly on-
screen dashboard allows the user to acquire data, calibrate spectral displays, and manipulate post acquisition
data. The speed of the system is only dependent on the integration time, readout rate of the camera and the PC
capabilities.
• The Andor Solis software is also compatible with other spectroscopic data analysis like GRAMS/Al. Mechelle
spectrographs are integrated with CCD, sCMOS or ICCD detectors form Andor Technology, which enables
the user to rapidly obtain accurate data. This makes the Mechelle spectrograph highly attractive to many
spectroscopic applications like Laser Induced Breakdown Spectroscopy, Raman spectroscopy or Laser ablation.
