Centaurus™

Centaurus™

Centaurus is a scintillation type Cathodoluminescence (CL) panchromatic detector and/or Backscattered Electron (BSE) detector, which can generate either high-resolution CL images or be easily converted to a BSE imaging detector for compositional imaging (with topographic information). With a user-exchangeable tip, the Centaurus can be converted between CL and BSE imaging, providing an additional function for little extra cost.

Centaurus gives excellent images at low kV – ideal for those studying fragile and beam-sensitive samples. Changing from CL to BSE is easily achieved by swapping the mirrored tip to a phosphor coated tip. A suitable free chamber port and AUX video input are required on the SEM. Cathodoluminescence (CL): Available for most conventional tungsten and FEG SEMs Excellent low kV performance High performance parabolic collection mirror High spatial resolution Operates in HV and LV mode Compositional monochromatic video output Dynamic range: 185-850nm (standard), optional wider range (400-1200nm) Backscatter (BSE): Phosphor or YAG scintillator options Good atomic number resolution Dynamic range: 300-650nm High performance parabolic scintillator (or YAG crystal) System options: Motorised insertion with Bellows sealing: The Motorised Centaurus Detector has all the functions of the manual model but with motorised insertion and welded bellows sealing. Its main application is for mounting in an inconvenient place, often behind the electron optical column. Its use is invaluable systems used in hazardous environments such as ”hot cells”. Additional BSE or CL tips: Purchase a CL system with additional BSE tip. Exchangeable PMTs: PMT tubes are user exchangeable to optimise collection wavelength.
