Stokes Laser Ellipsometer LSE-USB
Description
The model LSE-USB with convenient USB interface uses advanced StokesMeter™ technology (previous winner of Photonics Spectra and R&D 100 best new products awards). The unit's simple robust design offers unprecedented ease of use and instantaneous measurement. It is a popular alternative to overly complicated ellipsometers for precise routine measurement. Unlike other ellipsometers, StokesMeter™ technology uses no moving parts and no modulators to quickly and accurately determine the complete polarization state of the He-Ne laser measuring beam at a 70° incidence angle. The laser light source has ample light intensity for increased measurement accuracy of absorbing and rough scattering films.
Laser sources have the added advantage of being spectrally precise, stable and long lasting. Lasers permit optimum instrument design using optics, detectors and other components so that measurements can be made highly accurate. The LSE-USB design features a small footprint yet it can accommodate large samples up to 300mm. The sample stage can be locked in place or easily moved by hand to measure any point on the sample surface. The stage includes a manual tilt and table height adjustment using an alignment screen on the computer.
