Vacuum Evaporation System

This vacuum evaporation system with its suitable dimensions is capable of reaching the desired pressure in a short time and coating process can take place within a few minutes. It is suitable for research laboratory and electron microscopy applications.

Touch Screen Control with Colorful Display

DTT, the desk vacuum thermal evaporator, is equipped with a 7” colored touch screen with full automatic control and data input that can be operated by even inexperienced users. The vacuum and deposition information can be observed as digital data or curves on the touchscreen. Information of the last 300 coatings can also be saved in the history page.

Thermal Evaporation Sources(boat/basket/coil)

The DTT, desk vacuum thermal coater, can be fitted with three independent heat resistance thermal evaporation sources. The good design of the evaporation source holder causes no contamination from source materials on each other. The length of the source holders can be adjusted in the range of 5cm~9cm.

Clean Vacuum

The vacuum chamber is a heat resistance Cylindrical Pyrex with 300 mm OD and 200 mm H. The DTT is fitted with an internally mounted 90 L/s turbomolecular pump backed by a two-stage rotary pump which introduces clean vacuum without oil contamination that is normally present with an ordinary diffusion pump.
