Comparison of Two Detector and Three Detector Models The UV-3600i Plus is newly equipped with an InGaAs detector in addition to the photomultiplier tube (PMT) and cooled PbS detectors. That results in less noise than a two-detector (PMT and PbS detectors) model, especially in the region detected by the InGaAs detector (900 to 1600 nm). UV-3600i Plus Two-Detector Model The figure on the right shows transmittance spectra (spectral bandwidth 2nm) for water measured with the UV-3600i Plus (InGaAs detector and cooled PbS detector) and a two-detector model (PbS detector) in the range of 1,370 to 1,600...

E le ctrica l, Elec tronic s, and Optic s Transmittance Measurement of Lenses Imaging devices, such as mobile phones, digital cameras, and security cameras, are all equipped with lenses. The transmittance of a lens is one factor that determines lens performance. However, because the lens itself focuses light, it is an especially difficult type of sample to measure accurately. Because of the focal capability of lenses, the total light passing through the spectrophotometer during the measurement of the baseline can be different than after passing through the lens during measurement due to refraction....

Options Used for Measurements E le ctrica l, Elec tronic s, and Optic s Transmittance Measurement of Rolled Plate Glass for Solar Cell Rolled plate glass is a plate glass with rough surface. When it is scanned by a small integrating sphere, large steps at the detector switching wavelength may occur, and correct results may not be obtained. When run by an ISR-1503 with an of 150 mmø, and the sample was turned with 0, 45 and 90 degree, obtained spectra were almost same. And those spectra had very small steps at the detector switching wavelength. In addition to rolled plate glass for solar cell,...

Options Used for Measurements Ele ctrica l, Elec tronic s, and Optic s Band Gap Calculation Research into solar-cell and photocatalytic materials often involves the measurement of the band gap*, which is a basic physical property of the materials. Shown below are the diffuse reflectance spectra of three semiconductor materials used in the production of solar cells using the ISR-603 integrating sphere. The absorption edge, the wavelength where the reflectance decreases, differs depending upon the sample type. This difference indicates a difference in the band gap of the samples. The band gaps...
