Lip glosses are intended to add shine to the Lips, and may also add a tint of color, as well as being scented or flavored.
Lip Gloss was invented by Max Factory in 1930. He wanted to create a lip product that would make lips shiny and glossy for films.Factor created makeup for the movie industry. He developed makeup specifically for actresses starring in black and white films. Women were inspired by movie actresses and they also wanted makeup. The first commercially available lip gloss was Max factory's X-Rated, launched in 1932.The original formula was sold up until 2003, when procter and gamble retired the product.
Lip gloss is usually used as a cosmetic, however some offer moisturizing benefits or protection from the elements and other natural causes. Lip gloss containing sunscreen was first advertised by actress lillian gish
In 1973, Bonne Bell introduced the first flavored lip gloss, Lip smackers. Lip Smackers were, and still are, popular among young teenagers. Initially Lip Smackers came in two sizes: small and big. The small ones could be kept in the pocket and the big ones had a rope to hang around the neck. It was advertised that before a date, a teen girl should choose an appropriate flavor because that would be her date's first taste when his lips kissed hers
Natural makeup companies have made progress in creating lip gloss with mainly natural ingredients except for preservatives.
Introduction:
On August 19, 2013, the State Council released the "Broadband China" Strategy and Implementation Plan, which mentioned "increasing the support for the development and industrialization of high-end products such as core chips for key equipment, high-end optoelectronic devices, and operating systems."

A huge market of over one trillion yuan from application service providers to terminal manufacturers.
Optical transmission and switching, optical access and optical devices are the largest market segments in the optical communications industry, and the optical device industry is the most rapidly developing field in recent years. Optical devices are the foundation and core of the optical fiber communication system, and also the key to development. It is a forward-looking, pioneering and exploratory strategically demanding high technology in the field of optical fiber communication, and it can best represent a country in the field of optical fiber communication technology.

The optoelectronic device industry that has initially taken shape has already formed and achieved high speed. development of.
Optical communication devices are divided into optical active devices and optical passive devices. This article briefly introduces the classification, packaging type, structure and electrical properties of optical passive devices. In the production process of optical passive devices, Zhuoli Hanguang Can provide tooling solutions, equipment improvements and other aspects to explain.
1 Classification of optical passive devices An optical passive device is an optical component that can perform a certain optical function by itself without resorting to any external light or electric energy. Its working principle follows geometric optical theory and physical optical theory. Various technical indicators, various calculation formulas and various test methods are closely related to fiber optics and integrated optics. According to different manufacturing processes, optical passive devices can be divided into fiber optic passive devices and integrated optical passive devices; optical passive devices can be divided into: fiber collimator, connector, optical coupler, Optical attenuator, optical isolator, optical wavelength division multiplexer, polarized optical multiplexer, optical switch, optical circulator, etc.
1.1 Optical fiber collimator The optical fiber collimator is formed by precisely positioning the pigtail and the self-focusing lens. It can convert the transmitted light in the fiber into collimated light (parallel light), or couple external parallel (approximately parallel) light into the single-mode fiber.

1.2 Optical fiber connector Optical fiber connector is a detachable (movable) device between optical fiber and optical fiber. It precisely connects the two end Faces of the optical fiber so that the optical energy output by the transmitting fiber can be coupled to the receiver to the maximum. Fiber optics, and to minimize the impact on the system due to its involvement in the optical link, this is the basic requirements of fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.
Figure 1.2 Schematic diagram of optical fiber connector docking Optical fiber connectors are widely used and have a wide variety. According to the different transmission media, it can be divided into common single-mode and multimode connectors of silicon-based optical fibers, and other optical fiber connectors such as plastic optical fiber connector docking principle glue as transmission media; according to the structure of the connector, it can be divided For: FC, SC, ST, LC, D4, DIN, MU, MT, etc .; according to the shape of the fiber end face, there are FC, PC (including SPC or UPC) and APC; there are single cores according to the number of fiber core And multi-core (such as MT-RJ) points. In the actual application process, we generally distinguish according to the structure of the optical fiber connector. The three commonly used connectors are shown in the figure below.

1.3 Optocoupler Optocoupler is an important optical passive device, which can transmit the optical signal in the coupling area of ​​the special structure and then redistribute it. From the function, it can be divided into optical power distribution coupler and optical wavelength distribution coupler. It is commonly a planar waveguide type optical power splitter.

1.4 Optical attenuator Optical attenuator is an important optical passive device, which is often used to absorb or reflect the optical power margin in the system, to evaluate the loss of the system and various tests. There are many types of optical attenuators that can attenuate optical signals according to user requirements. It can be roughly divided into displacement optical attenuator, direct coating optical attenuator, attenuating film type, and liquid crystal optical attenuator.

1.5 Optical isolator The optical isolator mainly solves the problem of light reflection in the optical path. It is a non-reciprocal passive device that only allows light to be transmitted along the optical path in the forward direction. Its working principle is based on the non-reciprocity of Faraday rotation. The light reflected by the fiber echo can be well isolated by the optical isolator. There are two main types, spatial polarization-dependent optical isolators and polarization-independent optical isolators.

1.6 Optical wavelength division multiplexer The wavelength division multiplexing technology is a transmission technology in optical fiber communication. It uses the characteristics of one optical fiber to transmit multiple optical carriers of different wavelengths at the same time, and divides the possible wavelength range of the optical fiber into several. Band, each band is used as an independent channel to transmit an optical signal of a predetermined wavelength. This greatly improves the bandwidth utilization of single-mode fiber. Optical wavelength division multiplexer is an optical passive device that separates and synthesizes the wavelength of light waves. One port of the optical wavelength division multiplexer serves as the output / input of the device, and N ports serve as the input / output of the device.
It is worth mentioning that arrayed waveguide gratings (AWG) are commonly used for optical (de) multiplexers in wavelength division multiplexing WDM systems. These devices can combine many wavelengths of light into a single optical fiber, thereby improving the optical fiber network. Of communication efficiency.
Arrayed waveguide switches are based on the basic optical principle of linear interference of light of different wavelengths, which means that if each channel uses light with a fine microwave length difference, many channels of light can be carried by a single fiber, and only negligible Signal crosstalk. Array waveguides are turned on. At the transmitting end, multiple channels of light can be combined into a single fiber. At the same time, at the receiving end, these lights can also be separated again.

1.7 Polarization beam combiner (split) beam splitter Because of the ellipticity and residual stress that are difficult to overcome in the production of ordinary optical fibers, as well as the inevitable influence of external forces and magnetic fields during use, ordinary optical fibers will randomly change the two degenerate modes transmitted in The phase difference makes the polarization state change randomly. Polarized beam combiner is to combine two linearly polarized lights with orthogonal polarization directions into one beam.
