Massager

Foot massager is an instrument or device that inherits ancient foot massage techniques and is manufactured based on modern technology. It massages the feet of the human body (including soles, insteps, ankles, etc.) in different forms to achieve health care. . Foot massager function. 1. Promote blood circulation and increase metabolism, thereby improving sleep, so that the brain can get sufficient oxygen, and make you refreshed and clear minded; 2. It can prevent and improve high blood pressure, rheumatism, and back pain; 3. It can gradually improve foot problems. 4. It is effective for knee inflammation, rheumatism and joint pain. 5. Relieve edema, varicose veins and paralysis of the legs. 6. Promote the circulation of qi and blood in the legs and prevent and treat gout. 7. Regular use can improve insomnia and strengthen the function of the digestive system.

A plano-convex cylindrical lens is used to condense light in one axis. A positive plano cylindrical lens is able to create a line image from a point of light, to change the aspect ratio of an image or to focus collimated input light to a line. Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping. If you have any demand, please contact BRD Optical. Descriptions Of Plano Convex Cylindrical Lens The Plano spherical lens acts symmetrically on the incident light in both directions, while the cylindrical convex lens acts in only one direction on the incident light. A typical application is to shape a deformed beam with a pair of plano convex cylindrical lenses. A pair of positive plano-convex cylindrical lenses can be used to collimate and round the output of the laser diode. Another possible application is to focus the diverging beam onto the detector array with a single plano convex cylindrical lens. In order to minimize the spherical aberration, when the collimated beams are concentrated into one line, the collimated light should be incident on the curved surface of the lens, and when the quasi-linear source is used, the line source should be incident on the plane of the lens. BRD Optical was founded in 2004, and is located in the city of Changchun-the optic base of China with a beautiful view and profound optical culture. We have state-of-the-art, modern technology machines for manufacturing and inspecting all kinds of precision optics. BRD optical co. ltd occupies an area of 2,000 square meters, supported by 120 workers.
