DTT Thermal evaporator

Request a quotation

The DTT is a desktop, a turbomolecular-pumped thermal evaporator for vacuum deposition of thin films. The triple-source evaporation with evaporation source (boat/basket / coil) selection system is ideal for deposition of multilayers or alloys.

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 9 – 5 cm.
