Spectrophotometry - Wikipedia
Spectrophotometry is a tool that hinges on the quantitative analysis of molecules depending on how much light is absorbed by colored compounds. Important features of spectrophotometers are spectral bandwidth (the range of colors it can transmit through the test sample), the percentage of sample transmission, the logarithmic range of sample ...
分光光度法 - 维基百科，自由的百科全书
在化学中， 分光光度法 （英語： Spectrophotometry）是材料的反射或透射特性随波长变化的定量测量 [2]。 它比一般的 电磁光谱法 更具体，因为分光光度法处理 可见光，近 紫外光 和近 红外光，但不包括 时间分辨光谱 （英语：Time-resolved spectroscopy） 技术。 概论. 分光光度法是一种工具，取决于对有色化合物吸收多少光，对分子进行定量分析。 分光光度法使用称为分光光度计的 光度计，该 光度计 可以测量光束强度作为其颜色（波长）的函数。 分光光度计的重要特征是 …
Spectrophotography With a GRISM Star Spectrograph
2015年8月16日 · The GRISM star spectrograph (GSS) can be inserted on-axis into the telescope's light path, with no need for additional collimating or projection optics which is required with virtually all other sophisticated spectrograhs. In fact, using the GRISM star spectrograph is no more complicated than prime focus photography.

Spectrophotometry - Tip Biosystems
2023年12月15日 · Spectrophotometry is a standard and inexpensive technique to measure light absorption or the amount of chemicals in a solution. It uses a light beam which passes through the sample, and each compound in the solution absorbs or transmits light over a certain wavelength.
Ultraviolet Visible Spectrophotometry - ScienceDirect Topics
Ultraviolet–visible (UV–visible) spectrophotometry is primarily a quantitative analytical technique concerned with the absorption of near-UV (180–390 nm) or visible (390–780 nm) radiation by chemical species in solution. These regions of the electromagnetic spectrum (see Table 1) provide energy that gives rise to electronic transitions.
