FAQ about Optoisolators - Logic Output
-
1. What is opto-isolation output?
Opto-isolation, also known as opto-coupling, is a technology based on the photoelectric effect for isolating and transmitting electrical signals. By using opto-isolators, the input circuit can be effectively isolated from the output circuit to prevent interference from factors such as current, noise and high voltage. This article will introduce the definition, principle, application, advantages and safety of opto-isolation in depth.

2. How does an optical isolator work?
The working principle of an optical isolator includes the following aspects:
Absorption and reflection: The optical isolator absorbs light of a specific wavelength and then reflects the light in a direction through multiple reflective media.
Multilayer structure: Its core is multiple layers or multiple pieces of material, each with a different refractive index, which changes the propagation path and reflection probability of light in different layers.
Spectral screening: By adjusting the refractive index of each layer of material, the absorption or emission capacity of light of different wavelengths can be controlled to achieve effective separation of light in a specific band.
Optical isolators are widely used in optical instruments (such as microscopes, projectors, telescopes, etc.), optical communications, optical detection and other fields. -
3. What is the working principle of an optocoupler?
The working principle of an optocoupler (optocoupler) is to achieve the conversion and transmission between electrical and optical signals through the photoelectric effect. The basic structure of the optocoupler includes a light-emitting diode (LED) and a photosensitive element (such as a photodiode, phototransistor, etc.), which are encapsulated in the same housing. When the electrical signal at the input end drives the LED to emit light, the emitted light is received by the photosensitive element, and the photosensitive element generates a corresponding electrical signal, thereby realizing the transmission of the electrical signal.
Detailed description of the working principle of the optocoupler
Light-emitting diode (LED): When the electrical signal at the input end drives the LED to emit light, the LED emits light.
Photosensitive element: The photosensitive element (such as a photodiode, phototransistor, etc.) receives the light emitted by the LED and converts it into an electrical signal.
Electrical signal transmission: The electrical signal generated by the photosensitive element is output through the output end to complete the transmission of the electrical signal. Since the optical signal is completely isolated electrically, this transmission method can effectively prevent interference between electrical signals and the influence of high voltage on low voltage circuits.
