UV-Vis Absorption Spectroscopy
The photomultiplier tube is a commonly used detector in UV-Vis spectroscopy. It consists of a photoemissive cathode (a cathode which emits electrons when struck by photons of radiation),

The device at the bottom was used to attach the spectrometer to the telescope: the ring clamped around the telescope tube and the tubes above and below the collimator arm on the right-hand side slipped
Spectrometer Basics
These instruments have advantages over a single detector instrument where there are no moving parts which reduce the cost, the size and the power consumption especially beneficial for field use
Spectrometer
A spectrometer 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. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer
Optical Spectrometers introduction
Avantes'' high-sensitivity spectrometers have a revolutionary optical bench design with multiple toroid mirrors which ensure that the full numerical aperture of the fiber entrance will be projected on the
Long-Slit Spectrometers Definition
Long-slit spectrometers use a long, narrow slit to capture light from a wide field of view, allowing them to analyze the spectra of extended celestial objects like galaxies and nebulae.
