The China-US Mobile Medical Health Report released on May 22 shows that China Mobile's health care market has a very large space for development. By 2017, China and Japan will occupy the top two in the Asia Pacific mobile health market, with 37% and 21% respectively. China's mobile medical health market has reached 1.86 billion yuan in 2012, and it is predicted that it will exceed 10 billion yuan by 2017. The report shows that China's mobile medical market has huge service needs. First, medical expenses continue to rise. In 2011, it already accounted for 5.15% of China's GDP, with a total of 2.4 trillion yuan. Secondly, the problem of population aging is intensifying. In 2012, the proportion of the elderly over 65 years old in China exceeded 10%, and by 2050 it will reach 30%. Again, the medical expenses of individuals and families are under great pressure. From a statistical point of view, patients have to bear 35% to 50% of medical expenses. Therefore, the introduction of medical mobile health technology or service concept will effectively reduce the incidence rate, reduce the medical expenses, and improve the health level. At present, there are 260 million people diagnosed with chronic diseases in China, and it will consume more resources and consume more resources. The long-term monitoring and treatment of chronic diseases requires a combination of mobile technology. In addition, the prevalence of cardiovascular disease in China is expected to increase by a factor of 0.5 in the next 20 years. According to statistics, many patients are dying during sleep. Therefore, it is necessary to prevent health emergencies and reduce morbidity and mortality. All of these have brought a lot of market space for the development of China Mobile's medical and health services. Mobile medical health has four major advantages. First, because of its portability, it can expand access to medical services. Second, it can reduce doctors' misdiagnosis, optimize medical procedures, and improve efficiency. Third, the patient can be provided with some services for consultation or consultation. Fourth, through information technology, it can help the government to better collect and analyze relevant data, and provide a good foundation for policy formulation in the field of health care. Cao Shumin, dean of the Institute of Telecommunications Research, Ministry of Industry and Information Technology, believes that the development of mobile communications and mobile Internet provides a very good means for China to respond to the challenges of medical health services. Mobile medical health services will effectively alleviate the shortage of quality medical resources. The problem is to reduce medical expenses and achieve equalization of basic medical and health services. As of the first quarter of this year, China Mobile Internet users have reached 850 million. China is already the world's largest market for mobile smart terminals. According to Li Haihua, deputy chief engineer of the Institute of Standards of the Institute of Telecommunications Research, Ministry of Industry and Information Technology, according to the latest data released by the China Internet Network Information Center in July 2013, the mobile Internet usage rate of mobile phones in rural China has reached 78.9%, close to 80%. Therefore, the combination of mobile medical and mobile terminal technologies will play a significant role in improving the access to medical services, access and service channels, and will also promote the development of the entire medical mobile market. The dichroic mirror (color separation filter) can be used to isolate a specific range of the visible spectrum, a small amount of color used in the addition and photocopier in the color balance.
Its main feature is that the size can be made quite large. Thin film filters generally transmit longer wavelengths and are mostly used as infrared filters. The latter is to form a certain thickness of high refractive index or low refractive index metal-dielectric-metal film or all-dielectric film alternately on a certain substrate by vacuum coating, forming a low-order, multi-stage tandem solid method Brie-Perot interferometer. The choice of film material, thickness and connection mode is determined by the required center wavelength and transmission bandwidth λ.

The type of filters in the incident beam can be divided into two or more beam applications also play a big role.
Optical Filters are used to selectively transmit or reject a wavelength or range of wavelengths. Optical Filters are used in applications such as fluorescence microscopy, clinical chemistry, spectroscopy, or machine vision inspection. Optical Filters are ideal for life science, imaging, industrial, or defense industries.
