UNECS-Portable

Compact Light-weighted Portable Type

UNECS series is a kind of spectroscopic ellipsometers to measure the refractive index and thickness of the thin film quickly and accurately. It adopts an unique measurement method, and realizes the compact size and high-speed measurement .

UNECS-Portable measurement unit weight is only 2.2kg.  It is easy to be carried for vacuum equipments site acceptance test and can measure large size samples by detaching its sample stage and putting it directly on samples.

Features

  • High-speed Measurement :
    The snapshot measurement method is realized and the high-speed measurement is 20ms per point.
  • Visible Spectral Range :
    The spectral wavelength range can be selected. The standard type is 530nm to 750nm and the visible spectral type is 380nm~760nm.
  • Compact Sensor Unit :
    The sensor unit is light-weighted and very compact. It consists of an optical element that does not have any rotating mechanism. In addition, there is no need for any periodic maintenance.
  • Strong Product-line :
    There is a strong products line with the portable type, the manual/automatic stage type, the built-in type and the large substrate type etc.
