Widest spectral range

The SENresearch ellipsometer family covers the widest spectral range from 190 nm (deep UV) to 3,500 nm (NIR) in one tool. FTIR is applied in the near infrared, allowing an extension to 3,500 nm at highest spectral resolution and speed.

Step Scan Analyzer principle:

The Step Scan Analyzer principle is a unique feature of the SENTECH ellipsometer family. During data acquisition, polarizer and wide band compensator are fixed to provide highest accuracy of the ellipsometric measurement.

The SENresearch measures thin film thickness, refractive index, extinction coefficient, and related properties of bulk materials, single layers, and multi‑layer stacks. Isotropic and anisotropic materials, surface and interface roughness as well as gradients can be analyzed. Furthermore, SpectraRay/3, SENTECH proprietary ellipsometer software, treats sample effects like depolarization, non-uniformity, scattering (Mueller-matrix), and backside reflection.

The SENresearch represents the high end of SENTECH ellipsometers. The compact table top instrument comprises the ellipsometer optics, goniometer, sample platform, auto-collimating telescope, light source, and detection unit. It can be extended by a variety of options Options: Spectral ranges Automated goniometer Microspot Mapping stages
(50x50 – 300x300 mm) Autofocus, -alignment Video camera Reflectometer Sample cells Heating stage Cryostat for any R & D and routine application.

The SENresearch is focused on speed and accuracy for insitu and exsitu measurements of thin films wherever they are applied. Applications range from measuring on textured surfaces to determining the conductivity of TCO films, from insitu monitoring of deposition processes to offline mapping on large glass panels. With the latest development launched by SENTECH, magneto‑optical Spectral generalized magneto-optical ellipsometer – combined Kerr spectroscopy, MOKE, and spectroscopic ellipsometry properties can be characterized.
