Great Summer Sun and 7 Supplements
Great heat is the hottest year and the most vigorous phase of human yang. In order to comply with the weather, the human body is in a situation where "yang is outside and inside is empty". That is, yang is all on the surface of the body, and evil spirits are easy to take advantage of. If the heatstroke cools excessively, cold and cold, it is easy to cause the decline of yang in the body. Summer heatstroke cooling should be careful greedy cool food cold spleen and stomach If the human body is living in the cold environment of air-conditioner manufacturing for a long time, it will easily damage the “guardian yang†and “pulmonary yang†of the human body. It will be prone to summer colds, cough, asthma, and even increase the chance of these diseases occurring in the winter; excessive greed Eating iced cold drinks can easily damage the “spleen yang†and “weiyang†and cause gastric pain and diarrhea. Experts reminded: When the heat of the summer heat, we must pay attention to Fuyang. Care is taken to protect the body's yang and keep it vigorous, in order to maintain summer health and achieve the goal of “winter disease and summer diseaseâ€. There are 3 types of pain in the body: lack of yang: The doctor thinks that the ten diseases and nine pains are painful, and there are pain and illness. Many people will experience pain in the back of the body, such as the back of the neck, and these are mostly people with insufficient yang, and they need more help. 1, cold pain: "The pain is cold and chilly," and "there is no general pain." The pain is cold and warm, and it is common in lumbar ridges, sacral abdomen and joints and other limbs. Due to cold pathogens, the lack of yang can cause organs and limbs to lose warmth. 2, hidden pain: “Worry is not painful†refers to the pain caused by various causes of qi, blood, yin and yang, which causes the organs and meridians to lose their warmth, nourishment, and support. Head pain, negative blood loss; chest pain, weakness; rib pain, lack of liver yin; stomach palsy pain, stomach yin deficiency, or spleen and stomach yang; hidden pain in the teeth, for false fire disturbance, or Blood deficiency. 3, heavy pain: Ww. Refers to pain and a heavy feeling. Common in the head, limbs, waist and body, mostly due to dampness trap caused by dampness. These are all signs of losing the yang. Fuyang can improve these conditions. For example, Tianzhu is a good way to help Yang and help prevent hidden pain. Small ball lenses are widely used to couple optical fibers and semiconductor lasers, or another optical fiber, or light detectors.
The small ball lens is much smaller than the normal lens, and the whole is polished, so be careful when using it. However, it can reduce the size and weight of the device.
Ball lenses feature short back focal lengths to minimize the distance needed from the ball Lens to the optical fiber. Ball lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications.
Half-Ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy, microscopy, optical pick-up devices,and laser measurement systems.

Can be divided into two types of small ball lenses without coating and anti-reflection coating. The anti-reflection film is a single-layer MgF2 film, corresponding to three wavelength bands: 400-700 nm, 700-900 nm and 1300-1550 nm.
The design wavelength of the lens is 587.6nm (yellow helium line [d line]).
1,Excellent UV Transmission
2,Low Coefficient of Thermal Expansion
