Selection skills of Optical Element
Optical Element is usually a spherical optical element made of glass or plastic. Optical Element is mainly composed of convex lens, concave lens, plano-convex lens, plano-concave lens, etc. Optical Element is realized by the principle of light refraction in the optical system: light gathering, light dispersion, optical imaging; the optical lens is designed to be composed of multiple lenses, which can optimize color correction and correct spherical aberration.
Optical Element can be widely used in various security, automotive, digital cameras, lasers, optical instruments and other fields. As the market continues to evolve, so does the lens technology. A lens is a refractor whose refracting surface is a transparent body with two spherical surfaces or a spherical surface and a plane surface. It has real images as well as virtual images.
The functions of Optical Element in the optical system are: focusing, collimating, and imaging. The lens usually needs to be coated with an anti-reflection coating to reduce the reflection on the surface of the lens, which can reduce the loss of light energy and make the image clearer.
Tips for Optical Element use:
1. In the case of choosing an optical lens, it must be remembered that the distance of the product is also affected by its own angle.
2. In general, when selecting an optical lens, the measurement results must be followed.
3. First understand the required light intensity requirements, and then select the optical lens according to the needs.
The above three points are tips that users can use when choosing an optical lens.
Purpose of Optical Element:
1. Fiber Array Coupling
2. Optical communication
3. Reconfigurable optical add-drop multiplexer, wavelength selective switch
4. Demultiplexer/multiplexer, optical cross-connect equipment
An Optical Element is an optical element made of a transparent substance that affects the wavefront curvature of light. It is a device that gathers or scatters light, producing images that are both real and virtual. Various common colorless optical glasses, including quartz, calcium fluoride, magnesium fluoride, silicon, germanium, zinc selenide and other materials, as well as plano-convex lenses, bi-convex lenses, plano-concave lenses, bi-convex lenses, hyperhemispheric lenses, small spherical lenses , Meniscus lenses, cylindrical lenses, strip mirrors, cemented mirrors, etc.
