Magnifying glass: Prisms can be used as magnifying glasses to view small fonts in software

　　Prisms have a wide range of applications in daily life, mainly including the following aspects:
　　Magnifying glass: Prisms can be used as magnifying glasses to view small fonts in software, inspect documents, coins, and small laboratory samples.
　　Optical instruments: Prisms play an important role in optical instruments such as telescopes, microscopes, projectors, and projection devices. Refracting prisms in telescopes can change the focal length, achieving different perspectives; binocular refracting prisms in microscopes can magnify tiny objects; and projection prisms in projectors and projection devices can project images to specific locations.
　　Eye protection: Prisms are sometimes added to lenses to form a combined optical system, helping to compensate for eye field shifts or deficiencies. Especially for people with slight eye deviations or impaired visual fields, prisms can significantly improve their visual experience.
　　Lighting systems: In some lighting equipment, prisms are used to improve light distribution and intensity. By controlling the refraction of light, they effectively diffuse the light source, improving the lighting effect. They are widely used in stage lighting, car headlights, and indoor lighting.
　　In addition, prisms also have important applications in spectral analysis, optical communication, laser technology, and biomedicine. For example, they are used in spectral analysis to decompose spectra, in optical communication to achieve wavelength division multiplexing technology, in laser technology to change the shape and direction of laser beams, and in biomedical research for high-resolution imaging of cells and tissues.
