Pulsed Carbon Fiber Evaporation

The desk vacuum carbon coater is able to perform pulsed carbon fiber evaporation. Short pulses provide more controlled deposition and significantly reduces the number of debris associated with traditional carbon deposition.

Carbon Rod Evaporation (Optional)

The desk high vacuum carbon coater could be equipped with carbon rod head (Optional). For this case an external 0-100 A high current power supply should be used instead of the internal high current power supply which is designed for carbon fiber evaporation.

Touch Screen Control

Desk carbon coater is equipped with a 7” colored touch screen with full automatic control utilizing a user-friendly software to control and adjust the deposition process data. The vacuum and coating sequence information can be monitored as digital data or curves on the touch screen. The last 300 coatings information is saved on the history page and can be transferred to PC by a USB port on the device.

Sample Holder Stages of DCT

The turbo-pumped carbon coater can be equipped with different sample stage configurations depending on the user requirements. The standard sample stage is rotatable with adjustable height and angle and can be changed easily. The rotary planetary sample stage is a good choice for uniform coating of porous specimens (Optional).

Clean Vacuum of DCT

The vacuum chamber is Cylindrical Pyrex. The DCT is fitted with an internally mounted 90 L/s turbomolecular pump, backed by a 6 m3/h two stage rotary vane pump. It introduces clean vacuum without oil contamination which normally exists with ordinary diffusion pump.
