What is an optical part
Optical parts, also known as optical components. The basic building block of an optical system. Most optical components function as imaging, such as lenses, prisms, mirrors, and so on.
There are also some parts that play a special role in the optical system (such as splitting, imaging, filtering, etc.), such as reticle, filter, grating for optical fiber parts. Holographic lenses, gradient index lenses, binary optics, etc., are new optical components that have emerged in the past 20 years.
Applied optics:
Since optics consists of many sub-disciplines that are closely related to physics and has a wide range of applications, there are also a series of sub-disciplines with strong application backgrounds.
For example, photometric and radiometrics for physical quantity measurement of electromagnetic radiation; colorimetry for measuring color vision and its psychophysical quantities caused by electromagnetic radiation with a normal average human eye as a receiver; and numerous technical optics such as optical systems Design and optical instrument theory, optical manufacturing and optical testing and interferometrics, thin film optics, fiber optics and integrated optics.
There are also branches that intersect with other disciplines, such as astronomical optics, ocean optics, remote sensing optics, atmospheric optics, physiological optics, and weapon optics.
