Optical Instruments
Optical instruments are devices that use light to measure, observe, or analyze objects or phenomena in space. These instruments include telescopes, cameras, spectrometers, and lidars, among others. Telescopes are used to observe distant objects in space, such as stars, galaxies, and planets. Cameras are used to capture images of celestial objects and phenomena, such as nebulae, supernovae, and auroras. Spectrometers are used to analyze the chemical composition of celestial objects by measuring the wavelengths of light they emit or absorb. Lidars are used to measure the distance to objects in space by emitting laser pulses and measuring the time it takes for the light to reflect back. Optical instruments are essential tools for astronomers and space scientists to study the universe and understand its properties and evolution.
