This tool is for high-throughput measurement of the near-infrared spectroscopic reflectance of thin film combinatorial library samples at temperatures ranging from 274 K to 358 K. Samples as large as 7.62 cm in diameter can be measured with an areal spatial resolution of < 1 mm2. The instrument provides full reflectance spectra from wavelengths of 400 nm to 2500 nm as a function of temperature.
A translation stage with 100 mm of travel in the sample x and y direction.
Thermoelectric heater/chiller sample stage with a calibrated temperature range of 274 K to 358 K
White light source with nominal wavelength range from 360 nm to 2400 nm
Fiber-optic coupled NIR spectrometer with a detection range of 900–2500 nm and UV-VIS spectrometer with a detection range of 200 nm to 850 nm.
System is contained within a Plexiglass dry chamber flushed with nitrogen-enriched air to prevent condensation
