VG cold

Our first Vacuum Generator HB 501 is fitted with a CFEG which enabled a high brightness, a sub-nanometer spatial resolution and a good (less than 0.3 eV) spectral resolution, making it ideal for medium resolution analysis applications. Although bought 30 years ago, the VG cold has been constantly improved with in-house made instrumentation, such as enhanced scanning, spectral imaging and EELS capabilities. More recently, it has been fitted with a Nitrogen cooled stage and a high throughput cathodoluminescence system. All these improvement make the VG HB 501 still very competitive if not unique for the structural and chemical analysis of fragile materials, and for the nanooptics studies at the nanometer scale.
