Optics refers to the branch of physics and engineering dealing with the behavior, properties, and manipulation of light. Modern optical technology enables precise control of electromagnetic waves across ultraviolet, visible, and infrared spectra. As fundamental components in imaging, sensing, and communication systems, optical components form the backbone of scientific research, industrial manufacturing, and consumer electronics.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Lenses | Focus/defocus light through curved surfaces | Microscope objectives, camera systems |
| Mirrors | Reflect light with controlled surface profiles | Laser resonators, telescopes |
| Prisms | Disperse or redirect light via refraction | Spectrometers, beam steering |
| Filters | Selectively transmit specific wavelengths | Medical imaging, fluorescence microscopy |
| Diffractive Optics | Manipulate light using micro/nanostructures | AR/VR displays, laser beam shaping |
Typical optical components consist of: - Substrate Material: Glass (BK7, fused silica), crystals (sapphire), or polymers - Surface Coatings: Anti-reflective (AR), high-reflective (HR), or wavelength-specific coatings - Mechanical Housing: Precision mounts with thermal expansion compensation - Active Elements (for adaptive optics): Piezoelectric actuators, liquid crystal layers
