Overview
DCT-T-300 with a 300 mm Dia. cylindrical chamber allows long-term deposition on samples with a diameter of up to 15 cm or several small specimens. The full-automatic programmable carbon coating process allows easy, precise, and repeatable performance.
Thermal evaporation of low melting point materials in two upward or downward directions, with adjustable distance of the thermal source to the substrate, is another advantageous feature of this coating machine.
Pulsed Carbon Fibre Evaporation
The desk high-vacuum carbon coating system is able to perform pulsed carbon fibre evaporation. Short pulses provide more controlled deposition and significantly reduces the amount of debris associated with traditional carbon deposition.
Carbon Rod Evaporation (optional)
This benchtop coating system could be equipped with a 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 fibre evaporation.
Thermal Evaporation
DCT-T-300 is equipped with a high-current power supply and low-voltage (Resistive) thermal evaporation platform suitable for a wide variety of thermal evaporation applications. The system allows controlled thermal evaporation of a wide range of materials onto the substrate. Different types of thermal evaporation sources (boat, basket, and coil) can be installed on the single thermal source holder.
Clean Vacuum of DCT-T-300
The vacuum chamber is Cylindrical Pyrex with 300 mm OD and 200 mm H. The DCT-T-300 is fitted with an internally mounted turbo molecular pump, backed by a 6 m3/h two-stage rotary vane pump (optional). It introduces clean vacuum without oil contamination which normally exists with an ordinary diffusion pump.
DCT-T-300 Touch Screen Control
DCT-T-300 is equipped with a 7” coloured touch screen with full automatic control utilising 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-T-300
The DCT-T-300 can be equipped with different customised sample stage configurations depending on the user requirements. The standard sample rotation stages are rotatable with adjustable height and angle and easy to change. The rotary planetary sample stage is a good choice for uniform coating of porous specimens (optional). For deposition on large samples, a 6-inch rotatable (no incline adjustable) sample holder stage is recommended (optional).
