The cathode ray is just a beam of electrons. The color of the fluorescence depends on the substance in the target.
Fluorescence spectroscopy is a type of spectroscopy that analyzes fluorescence from a provided sample. This uses a beam of light, often an ultraviolet light which then causes absorption spectroscopy to occur.

A single beam spectrophotometer is a type of spectrophotometer that measures the intensity of light at a specific wavelength. It uses a single beam of light that passes through a sample and a reference solution to determine the absorbance. Single beam spectrophotometers are simpler in design and are typically more affordable than double beam spectrophotometers.

A double 2x10 beam can typically span up to 12 feet without additional support.
A triple beam balance. (TBB)
it means double beam
A detection beam on a microscope is a focused light or electron beam used to capture the signals emitted by a sample under observation. It helps to gather information about the specimen's properties, such as its structure, composition, or fluorescence. Detection beams are crucial in generating images or data in various microscopy techniques, such as optical and electron microscopy.
A triple beam balance has three beams for measuring mass, while a double pan balance has two pans for comparing masses. Triple beam balances are typically more precise and accurate than double pan balances. Triple beam balances are commonly used in laboratories, while double pan balances are often used in classrooms for basic measurements.
It works on the following principles : (i)thermionic emission (ii)deflection of the electron beam by the electric and magnetic field (iii)fluorescence produced by the electron beam on a fluorescent screen
