Low Vacuum Sputter and Carbon Coaters for standard SEM

Choose from Five (5) Models:

  • DSR Sputter
  • DSR-L Sputter
  • DCR Carbon
  • DCR-L Carbon
  • DSCR Dual

The R-Series Desktop Coaters are high productivity tools that deliver consistent and repeatable results in the fully automated system that has an ergonomic design and compact footprint.  The R-series Desktop Coaters are available in 3 models to chose from:

  • DSR – dedicated Sputter Coater
  • DCR – dedicated Carbon Coater (fiber or rod)
  • DCR-L – Carbon Coater for large or multiple samples
  • DSCR – dual purpose Sputter and Carbon Coater

The DSR Sputter Coater model is a dedicated coating system which is able to coat noble metals such as gold (Au), palladium (Pd), platinum (Pt) and gold/palladium (Au/Pd) thin films on non-conductive or poorly conductive specimens, typically for SEM imaging and analysis. Uniform thin films with fine-grain sizes are formed in a fast cycle time suitable for standard scanning electron microscopy.  A special DSR-L model with larger chamber is available but requires a 4″ diameter (100mm) target which is custom and quite expensive for noble metal targets.

The DCR Carbon Coater model is a dedicated carbon coating system and can be configured with either a Thread or Rod carbon source.  Carbon thin films are essentially X-Ray transparent for EDS analysis and are applied to non-conductive or poorly conductive specimens, typically for advanced SEM/EDS analysis. The DCR-L model is a special version using a 300mm chamber allowing uniform coating onto larger samples or multiple metallurgical mounts simultaneously.

The DSCR combines both Sputter and Carbon coating into a modular unit for SEM sample preparation and can be configured as a sputter coater OR carbon coater (thread) with interchangeable heads in one instrument.

The external vacuum pump (included) achieves vacuum of less than 50 mTorr which is a suitable vacuum range for noble metal sputter coating and basic evaporative coating.  allows fast vacuum to be achieved resulting in an adequate coating grain size for most SEM analysis.  If samples will be examined using high resolution Field Emission SEM (FE-SEM) or TEM, then we recommend our T-Series Coaters which have an added turbo-molecular high vacuum pump for even smaller grain size coatings.

  • 2-year Factory Warranty

Functional Ease-of-Use Features

Touch Screen Controls 

All coaters come equipped with a 7” touch screen and fully automatic control allowing easy operation even by inexperienced users. The vacuum, current and deposition information can be observed as digital data or curves on the touch screen. Information of the last 300 coatings is also saved in the history page.

Sample Holders

All coater models can be equipped with different sample stage configurations depending on the user requirements. The standard sample stage holds up to 7 standard SEM pin stub mounts and is rotatable with adjustable height or angle.  The holders can be exchanged easily with other holders when requirements change.

The optional rotary planetary sample stage is a good choice for uniform coating of specimens with porosity or intricate 3D details where coating is needed in hard to reach features of the specimen.

Other holders are available for:

  • Glass Slides
  • Metallurgical mounts
  • Jeol and Hitachi style cylinder stubs
standard Tilt Rotate holder

Standard Tilt / Rotate Holder

Planetary Rotate Tilt stage

Optional Planetary Rotate / Tilt Holder

Pulsed Carbon Fiber Evaporation

The DCR and DSCR model coaters offer pulsed carbon fiber evaporation. Short pulses provide more controlled deposition and significantly reduces the amount of debris associated with traditional carbon deposition.  An Optional Carbon Rod coating head is available for the DCT model.
