Multiwavelength Laser Ellipsometers LSE-WS
Description
Multiwavelength Laser Ellipsometers give the user greater versatility in thickness and refractive index measurement of thin transparent and semi-transparent films. Laser light sources have 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. Their use permits optimum instrument design with optics, detectors and other components so that measurements can be made highly accurate. Separate laser sources offer backup reliability important to continuous operation and they are a excellent alternative to overly complicated less precise spectroscopic ellipsometers.
