Sometimes referred to as a UV–Vis spectrophotometer because it measured ... beyond the visible spectrum towards the ultraviolet could cost a laboratory as much as ...
Developed by Bausch & Lomb and launched in 1953, the Spectronic 20 was the first low-cost spectrophotometer. [5] It rapidly became an industry standard [7] due to its low cost, durability and ease of use, [8] and has been referred to as an "iconic lab spectrophotometer". [9] Approximately 600,000 units were sold over its nearly 60 year ...
A UV-Vis spectrophotometer is an analytical instrument that measures the amount of ultraviolet (UV) and visible light that is absorbed by a sample. It is a widely used technique in chemistry, biochemistry, and other fields, to identify and quantify compounds in a variety of samples.
The Cary 14 spectrophotometer was first produced in 1954 by the Applied Physics Corporation, which later was named the Cary Instruments Corporation after co-founder Howard Cary. [1] The instrument was a successor to the Cary 11, which was the first commercially available recording UV/Vis spectrophotometer. [3]
Ultraviolet-visible (UV-vis) spectroscopy involves energy levels that excite electronic transitions. Absorption of UV-vis light excites molecules that are in ground-states to their excited-states. [5] Visible region 400–700 nm spectrophotometry is used extensively in colorimetry science. It is a known fact that it operates best at the range ...

An XPS spectrometer. A spectrometer (/ s p ɛ k ˈ t r ɒ m ɪ t ər /) is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed.
