Desk Thermal Evaporator – DTT

Vac product DTT Three Shots header

The DTT is a desktop, turbomolecular-pumped thermal evaporator for vacuum deposition of thin films. Different evaporation sources (boat/basket/coil) can be installed on the triple-source evaporation system on the baseplate. Adjustable substrate holder position through the touch screen is ideal for the deposition of single/multilayers or alloys.

Thermal Evaporation Sources (Boat/basket/coil)

The DTT, desk thermal evaporator, 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 5-9cm.

Clean Vacuum of Desk Thermal Evaporator

The vacuum chamber is a Cylindrical Pyrex with 300 mm OD and 250 mm H, and the height can be multiplied by an optional extra cylindrical Pyrex of the same size. The DTT is fitted with an internally mounted 90 L/s turbomolecular pump, backed by a 6m3/h two-stage rotary vane pump (Optional). It introduces a clean vacuum without oil contamination which normally exists with an ordinary diffusion pump.

Touch screen control

Desk thermal evaporator is equipped with a 7” colored touch-screen panel using user-friendly software to control the deposition process data. The vacuum and coating sequence information can be observed as digital data or curves on the touchscreen and the last 300 coatings are saved on the history page.
