Using Spectroscopic Reflectance and Transmittance for Thin Film Measurement - MProbe NIR

The MProbe NIR system is used to measure spectroscopic reflectance and/or transmittance in NIR,  thereby allowing users to easily analyze applications that are optically opaque at either visible or UV wavelengths.

Note that the MProbe NIRHR, which functions at a wavelength range of 1500 nm to 1550 nm, allows users to acquire measurements for thick films and wafers such as quartz, Ge and Si. Some of the most common applications that the MProbe NIR is suitable for include: Solar cells absorbers (e.g. CIGS, CdTe), rough surface interfaces, other light scattering applications (high haze polymer web, layer with nanoparticles), Si, Ge and dryed polymers.
