What it is
The Hitachi UH 4150 is a UV-VIS-NIR spectrometer, an instrument that measures the absorption, transmission, or reflection of light over the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum.[1]
How it works
General reference — not yet source-verifiedA UV-VIS-NIR spectrometer operates by directing a light source through a monochromator that selects a narrow band of wavelengths, which then passes through or reflects off a sample. A detector measures the intensity of the transmitted or reflected light, and the instrument compares it to a reference beam to compute absorbance or transmittance spectra.
Where it fits in the process flow
General reference — not yet source-verifiedIn semiconductor and precision optics manufacturing, UV-VIS-NIR spectrometers are used for in-line or off-line characterization of thin films, antireflection coatings, and optical substrates. The instrument sits in the metrology or quality-control stage, after deposition or coating processes, to verify optical performance against specifications.
