The Nano-Tec gold coated microscope slides are intended for microscopy, AFM / SPM, nanotechnology and biotechnology applications. They are also useful as opaque light microscopy supports. The microscope slides are pre-cleaned before coating and coated with a 50nm of Au over a 5nm adhesion layer of Ti. Both Ti and Au are deposited in a dedicated high vacuum deposition system with electron beam evaporation sources. The gold coating is not atomically flat; there are height differences in the nm range. The Nano-Tec gold coated microscope slides are autoclavable. Individually packed in a microscope slide mailer.
