A double-convex lens is compose of two convex surfaces, has a positive focal length. Normally Bi-Convex lenses are most suitable where the object and image are on opposite sides of the lens, and are popular for many imaging applications.
Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens. Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.

1-2 groups to improve the fire pump to shorten the start-up time
At the beginning of October, the 12th group of Nong Bashi teachers improved the gasoline pump of the cotton fire-fighting equipment. After the improvement, the start time of the gasoline pump was only 10 seconds, which was 50 seconds shorter than the original start-up time. This technology changed the previous year, small gasoline pump height placed, start water must be added practice, the gasoline pump on the water source position, so that the pump always keep water, improve fire emergency capabilities.
