2022年9月28日 · A filter photometer has a single optical path between the source and detector, and is called a single-beam instrument. The instrument is calibrated to 0% T while using a shutter to block the source radiation from the detector.
8.4.1: Single Beam Instruments for Absorption Spectroscopy ...
The Spectronic 20 is a brand single-beam spectophotometer, designed to operate in the visible region of the spectrum across a wavelength range of 340 nm to 950 nm, with a spectral bandpass of 20 nm. It is designed for quantitative absorption measurement at single wavelengths.
The basic components of a spectrophotometer are shown in Figure 12.6. Figure 12.6 Schematic diagram of a single-beam spectrophotometer. The radiation source depends on which region of the electromagnetic spectrum is being used. Visible (VIS) radiation (~400-750 nm) is usually provided by a tungsten lamp.
Instrumentation of a UV-Visible Spectrophotometer - JASCO
There are two types of optical arrangements: single and double beam. In the single-beam configuration, the monochromator, sample, and detector are arranged in series and the obtained monochromatic light with intensity I 0 irradiates a sample and the transmitted light with intensity I is detected. Here, I/I 0 is the transmittance. Although the ...
