BACH Monochromator


Soft X-ray PGM: SXR 6G monochromator, manifactured by BESTEC GmbH  with optics from Zeiss.

The principle of operation is a SX700 design with off-center mirror rotation. The photons dispersion system is based on the Padmore VASGM (Variable Angle Spherical Grating Monochromator) scheme and it includes four different interchangeable spherical gratings. The first three gratings guarantee resolving powers of 20000-6000, 20000-6000 and 15000-5000 in the energy ranges 35-200 eV, 200-500 eV and 500-1600 eV respectively.




SG1 44 eV-349 eV (35 eV-42 eV available under special request) high resolving power: 20000-6000 flux>1011
SG2 158 eV-597 eV high resolving power: 20000-6000 flux>1011
SG3 491 eV-1600 eV high resolving power: 15000-5000 flux>1011
SG4 301 eV-1600 eV medium resolving power: 10000-2000 flux>1012
