About Instrument and its Applications :
The Cary 5000 UV-Vis-NIR spectrophotometer is a high-performance spectrophotometer with good photometric performance in the wavelength range of 180nm to 3300 nm. Using a PbSmart detector, the Cary 5000 extends its NIR range to 3300 nm making it a powerful tool for materials science research.
Common application of UV-Vis-NIR Spectrophotometer includes: measurement of transmittance, absorbance and reflectance spectrum, thin film thickness analysis, anti-reflection coating analysis, analysis of novel nanocomposite materials, colour measurements and colour matching, optical density measurements, optical bandgap analysis, etc.
