Laser ellipsometer SE 400adv PV
World standard for ARC
Currently over 330 of SE 400adv PV laser ellipsometer are in use to characterize antireflective coatings all over the world.
Analysis of rough surfaces
High sensitivity and ultra-low noise detection allow for measuring on non-ideal, stray light causing surfaces typical for textured Measurement on polycrystalline silicone mono- and multicrystalline silicon solar cells.
Extraordinary high stability and accuracy are main features of SE 400adv PV laser ellipsometer due to stable laser light source, temperature stabilized compensator setup, and ultra low noise detector.
The multiple angle laser ellipsometer SE 400adv PV provides film thickness and refractive index of antireflective single films on textured monocrystalline and multicrystalline silicon wafers at the HeNe laser wavelength of
The SE 400adv PV laser ellipsometer can especially analyze coatings of SiNx, ITO, TiO2 and thin passivation layers of SiO2 and Al2O3. Double layer stacks can be analyzed on smooth substrates.
The SE 400adv PV is a compact instrument, quickly up and running. SENTECH easy-to-use, recipe oriented software includes a comprehensive package of predefined applications that fit the requirements of
A portable laser ellipsometer for photovoltaic applications is available for setting up and testing large PECVD systems long before the whole production line is running.
