Expansion into the NIR region, offering incredible value
The unique single monochromator design of the V-670 requires fewer mirrors to provide a higher throughput resulting in a better signal-to-noise ratio over the entire spectral range. Many UV-Vis/NIR applications require
reflectance or transmittance measurements of special optics, films, and wafers. The optional large sample
compartment can directly accomodate large samples non-destructively. Several integrating spheres are available
including a remote optical fiber unit which can measure the diffuse reflection of a variety of solid samples, such as
pastes, clothing materials and food products.
Transmittance measurement of quartz window
Wavelength extension up to 3200 nm allows observation of H2O absorption in quartz.
Absolute Reflectance Spectra of 50 nm ITO on Si
(Using Automated Absolute Reflectance Measurement System)
Absolute reflectance spectra of 50 nm ITO (indium tin oxide) on silicon substrate, p-polarized light (left), and spolarized
light (right). Incidence angles are 5°, 15°, 25°, 35°, 45°. The ITO film is transparent in visible light while
highly conductive and widely used in LCD's, PD's and touch-panels.
NIR absorbance spectra of a fatty oil
An important characteristic of a fatty oil product is its iodine value (IV). The V-670 and a PLS (Partial Least Square) program allows determination of the iodine values in fatty oil samples, measuring differences in the spectra in the range from 2300 nm to 2500 nm. The differences in NIR absorbance can be attributed to differences in iodine values (i.e., concentrations of unsaturated C=C double bonds in the oil molecules). The differences in the spectra can be observed at approximately 1200, 1950, 2200 and 2400 nm.
