Linear Polarization Resistance (LPR) Monitoring
The electrochemical technique, commonly referred to as Linear Polarization Resistance, is the only corrosion monitoring method that allows corrosion rates to be measured directly, in real time. Although limited to electrolytically conducting liquids, the response time and data quality of this technique make it clearly superior, where applicable, to all other forms of corrosion monitoring.

Optical Spectrum Analyzer
an optical spectrum analyzer for analyzing short wavelengths from 350nm to 1000 nm. Because it adopts a Fourier spectrum system with a Michelson interferometer, the 8341 can measure the coherence. With its narrow wavelength resolution of 0.01nm * , the 8341 is very effective for the evaluation of not only CD/DVD laser diodes, but also for blue-violet laser diodes. In addition, the built-in He-Ne laser acts as a wavelength reference to ensure a high wavelength measurement accuracy of ±0.01nm * . Finally, with its fast 0.5s * measurement speed, the 8341 is ideal for building into systems for mass production and evaluating temperature characteristics of system components.

Spectroscopic Reflectometer
SR Series
Angstrom Sun Technologies, Inc.
Spectroscopic reflectometer (SR) tools are relative low cost and easy to use. To ensure accurate measurement on spectra, a long working distance and also adjustable working distance set up are professionally designed and considered. Since reflection spectra measurements require to use known reference to calibrate light intensity, it is hard to image that user could get accurate spectra without optimizing signal during such calibration because reference thickness is different from sample substrate's thickness in most of cases. Adjusting power output to lamp is our another consideration in ensuring a good measurement by reducing non-linearity effect of the detector.
