stokes laser ellipsometers

Ellipsometers give non-contact thickness and refractive index measurements of thin transparent and semi transparent films to sub-angstrom precision. Unlike other ellipsometers, Stokes Elipsometers utilize the complete state of polarization of the measuring beam to provide exceptional accuracy and precision. Gaertner has helped pioneer the field of ellipsometry and we offer high quality Stokes laser ellipsometers  for routine measurements in the semiconductor, solar, chemical, biological and other thin film industries. They are a popular alternative to overly complicated spectroscopic ellipsometers at an affordabe price.


Stokes Laser Ellipsometer LSE-USB

with convenient USB interface uses advanced StokesMeterô technology  (previous winner of  Photonics Spectra and R&D 100 best new products awards). The unit's simple design offers unprecedented ease of use, precision and instantaneous routine measurement at an affordable cost.

Stokes WAFERSKAN Laser Ellipsometer LSE-WS

is a high speed film thickness mapping system measuring one site per second including stage travel! It uses advanced StokesMeterô technology to give tilt-free, focus free, 2D/3D color thickness and index maps on any size wafer up to 300mm. Easy to use and affordably priced, the LSE-WS is a popular choice in a high precision scanning ellipsometer.

Multiwavelength Laser Ellipsometers L2W & L3W

Two and Three Wavelength Ellipsometers use  laser sources to analyze difficult films. They give refractive index results in near period regions, and measure the thickness of thicker films, and offer many of the advantages of spectroscopic ellipsometers without the complexity and cost.
