The BACHES Echelle Spectrograph<br />
• <strong>Resolution</strong> λ/∆λ = 14000-20000<br />
• Wavelength range λ = 400 -700 nm (without gaps)<br />
• 25 µm and 50 µm slits<br />
• Optical peak efficiency 31%<br />
• Compact and Lightweight<br />
• <strong>High</strong> mechanical stability<br />
• Optimised for KAF-1603E sized Detectors (13.8x9.2mm 2 , 9x9µm 2 pixels)<br />
• Can be used with DSLRs<br />
• Optimised for 8“-24“ f/10 Optics (can be used on larger ones)<br />

BACHES at the ESO La Silla<br />
1-m Telescope<br />
Part of an official ESO multi-spectrograph and<br />
telescope project to characterise the<br />
atmospheric water vapor content<br />
as part of pre-site testing for the eELT<br />
BACHES tuned for this project have a<br />
spectral resolution of R=20000 @ 718 nm<br />
