The principle and composition of frequency doubling lenses in laser accessories. Frequency doubling lenses can convert various invisible infrared beams into visible light, effectively detecting, tracking, calibrating, and identifying infrared beams. They are used in various fields such as near-infrared light detection of semiconductor lasers, tracking of infrared light-emitting diode emission light, calibration of YAG and other large laser beams, and detection of fiber optic communication signals. The infrared detection board is made of upconversion luminescent material, which can be powder, ceramic, or glass
Dot matrix is a mode of laser emission, in which a special image generator (CPG) is installed to change the emission mode of light. Dot matrix laser can emit focal spots of 50um-80um through a high focusing mirror, and scan these focal spots into up to six rectangular shapes (circular, square, rectangular, diamond, triangular, linear). The image generator (CPG) disperses the originally focused light spot into several tens to hundreds of smaller focal spots,
The optical beauty device uses laser, strong pulse light, E-light, and infrared as light sources to achieve beauty effects such as freckle removal, red blood line removal, skin rejuvenation, hair removal, eyebrow and tattoo removal. Due to the unique spectral characteristics of these light source products, it is necessary to use optical filters to achieve certain functional effects while avoiding stray light from causing damage to human skin
The principle of a filter is that the lenses of a beauty device are made of plastic or glass with special dyes added, and a red filter can only allow red light to pass through, and so on. The refractive index of glass sheets was originally similar to that of air, allowing all colors of light to pass through, making them transparent. However, after dyeing, the molecular structure changes and the refractive index also changes, resulting in changes in the passage of certain colors of light. For example, a beam of white light passing through a blue filter emits a beam of blue light, while green light and red light
The optical glass substrate of the filter mainly includes absorbing glass, such as HB850, JB9, JB1, ZB3, HB5, HB8 and other grades, optical glass K9, float glass, B270, quartz, sapphire, etc. Geometric dimensions and thickness: Considering the special application environment of the customer and the need for mechanical layout within the system, the geometric dimensions and thickness of the filter should be clearly defined, and an appropriate tolerance range should be provided. Features: Different types of materials, with
The principle of a smart toilet is that there is a sensing area on the body of the toilet. When a person enters, the sensing area will automatically sense and transmit information to the body, and the toilet seat will automatically flip up. This is just one aspect of the performance of intelligent toilets, and with the advancement of technology, smart toilets will become increasingly intelligent and functional, constantly meeting people's needs. So, what is the ultimate optical technology principle required for smart toilets? Where else can this technology be applied
Filter out infrared radiation: Color CCD can also sense infrared radiation, which can cause D.S.P to be unable to calculate the correct color. Therefore, a filter needs to be added to separate the infrared part of the light. Only color CCD needs to be equipped with a filter, and black and white do not need it. Coating can be done by vacuum coating or chemical coating. Chemical coating is a process of immersing quartz in a solvent for electroplating, which is low-cost but has uneven coating thickness and capacitance
With the rapid development of artificial intelligence and optoelectronic technology, many tech giants have entered the field of autonomous driving, such as Google's self driving cars and Baidu's self driving cars. Further develop and apply the technology of autonomous driving. Autonomous vehicles are actually an organic combination of mechanical control functions, AI technology, and optoelectronic technology. Ruicheng Optoelectronics takes you to further understand the role of LiDAR in autonomous vehicles and the application of optical filters in autonomous vehicles.
The main function of the field mirror is to: (1) improve the ability of the edge beam to be incident on the detector; (2) In the same main optical system, additional field mirrors will reduce the detector area. If the same detector area is used, the field of view can be expanded and the incident flux can be increased; (3) It is possible to allocate the position of the image plane to place the modulation disk, in order to solve the problem of having nowhere to place the modulator; (4) Make the non-uniform illumination on the photosensitive surface of the detector uniform; (5) When using a flat image
