We all know that every day the human body needs the supplement of energy. The food that is eaten is digested and metabolized in the body and oxidized to produce energy. In the process, free radicals are produced, which have a destructive effect on the activity of the enzyme proteins and thus accelerate the aging of the cells. Under the action of free radicals, collagen reacts, so that the skin does not get enough nutrients supply, resulting in decreased skin tissue viability, loss of elasticity, wrinkles, body skin aging, dark complexion and so on. At the same time, with the increase of age, free radicals increase, the degree of free radicals to corrode protein cells and adipocytes in the body is also deepening, lipofuscin accumulation more and more, resulting in the formation and appearance of the stain slowly. To remove this free radical, you should eat the following "restore food": 1, tomato Tomatoes are rich in lycopene, and lycopene is 20 times more powerful than vitamin C. It can be said to be an anti-oxidant fighter. Daily intake of 10 mg lycopene, for the removal of free radicals in the body, eliminate fatigue, improve the body's immune system, beauty skin has a clear role in promoting. Among them, the vitamin C content of tomato is higher, which can make the anti-oxidation firepower more fiercer. 2. Hawthorn Hawthorn contains flavonoids and vitamin C, carotene, etc. can block and reduce the formation of free radicals, enhance the body's immune system, as well as anti-aging, anti-cancer effect. 3, grapes The antioxidant power of the tomatoes is fierce, and the grapes are not inferior. Grape contains a large number of polyphenols, the most important of which is proanthocyanidin (0PC) - this material has anti-free radicals, protect cardiovascular and cerebrovascular, regulate blood lipids, prevent high blood pressure, anti-tumor and other effects. 4, mung beans Mungbean can help excrete various toxic substances that invade the body, including various heavy metals and other harmful substances, promote normal metabolism of the human body and reduce fine lines on the face. 5, soybeans Soybeans contain isoflavones and soya bean saponins, a natural antioxidant with a weak estrogen effect. Drinking soy milk can significantly reduce women's menopausal symptoms, but also has the effect of preventing cancer. It can reduce free radicals in the body and has a very good effect on beauty for women. 6, garlic Garlic contains a variety of antioxidant substances such as vitamin A, C and E, and selenium, which can eliminate various free radicals and protect the heart. Allicin in garlic has a strong ability to resist free radicals. It takes more than 15 minutes for garlic to be oxidized in the air. 7, pig blood The pig's blood is sweet and warm, and it is an ideal food for detoxification and cleansing of the intestines, blood tonic, and detoxification. Porcine blood contains a large amount of plasma proteins. After being decomposed by human stomach acid and digestive enzymes, it chemically reacts with dust and harmful metal particles that invade the gastrointestinal tract and becomes waste that is not easily absorbed and is excreted. In addition, pig blood is rich in iron, which has an ameliorating effect on anemic and pale looking people. 8, squid Because of the strong OMEGA-3 polyunsaturated fatty acids, they have a strong antioxidant effect. Of course, the wild squid's firepower is definitely superior to that of the farmed squid. 9, tea Tea polyphenols, an active ingredient in tea, is an antioxidant substance, and residents in areas where tea is often consumed have a low risk of cancer. It can be seen that tea polyphenols can not only eliminate free radicals and prevent the appearance of fine lines, but also prevent the occurrence of cancer. 10. Carrot Carrots not only enhance human immunity, but also have anti-cancer effects. It is also rich in carotene. Carotene can eliminate single-phase oxygen and free radicals that cause aging, slow down the process of human aging and prevent skin aging. 11, kelp Kelp is a vegetable in the sea. Because it grows in the sea, it is rich in trace elements and gums that promote the smooth metabolism of the human body. It also contains selenium and small amounts of calcium, magnesium, potassium, iron and other minerals involved in the capture of free radicals. The most important function for the human body is that it helps to regulate the physiological functions of the human body. For example, gelatin in kelp can promote the release of radioactive substances that penetrate the body. 12, spinach Spinach contains a large amount of β-carotene and iron, as well as a large amount of α-lipoic acid, which can provide the body with rich nutrition. The large amount of antioxidants in spinach can activate brain function and increase youthful vitality, helping prevent brain aging. 13, oats Oats rich in protein, calcium, riboflavin, thiamine, etc. are the only foods in the grain list that rank among the best antioxidants. Daily intake of the right amount of oats can speed up the body's metabolism, accelerate the synthesis of amino acids, remove free radicals from the body, and promote cell renewal. Stick to a bowl of oatmeal every day, it will make you radiant! 14, mushrooms Regular consumption can clean the blood and excrete toxic substances. It can also clean and purify the environment. 15, nuts Nuts rich in vitamin E (cashberries, walnuts, hazelnuts, peanuts, etc.) can scavenge free radicals, and in addition to their antioxidant properties, they can also repair skin tissue. However, because of the high fat content of nut foods, if excessive intake, not only the risk of obesity, oxidation caused by high fat will also damage the antioxidant effect of vitamin E. Therefore, dietitians advise people to eat this type of food in moderation, especially with care. Dove prism is used to rotate, invert, or retroreflect an image, depending upon the prism's rotation angle and the surface through which the light enters the prism. Dove Prisms are fabricated from N-BK7 glass for high transmission from the visible to the near-infrared spectral range.
Upon request, our prisms can be AR coated for the UV spectral range , VIS spectral range and IR spectral range.

Dove prisms can be thought of as right-angle prisms with the triangular apex removed, which reduces the weight of the prism and stray internal reflections. They introduce astigmatism when used with converging light, so we recommend using them with collimated light.
Image Rotation
Light is usually propagated along the longitudinal axis of a Dove prism. In this geometry, light reflects once from the bottom face, inverting the image on the other side. Rotation of the prism about the longitudinal axis rotates the image at twice the rate of the prism's rotation. For example, a 20° rotation of the prism results in a 40° rotated image. The AR-coated Dove prisms are designed specifically for the image rotation and inversion application.
Due to the high incidence angle, the light reflecting from the bottom face undergoes total internal reflection, even if the light's propagation axis and the prism's longitudinal axis are not exactly parallel. Hence, in a Dove prism, the magnitude of the internal transmission is limited only by absorption.
Retroreflection
When light is incident on the longest face, the Dove prism acts as a retroreflector or a right-angle prism. The light exits parallel to the input light (independent of the incidence angle) and is inverted by 180°. In situations with limited space or where more convenient mounting options are needed, the Dove prism can replace a retroreflector or right-angle prism.
