According to engineering construction personnel, the current common practice is for the owner to select the bathtub first, and the construction personnel will know the size before renovating. However, it is often the case that after the water circuit is reformed, the bathtub cannot be installed, probably due to inaccurate dimensional measurements. As the owner, should review the construction drawings and the actual size is consistent, in the measurement must also pay attention to the thickness of the tiles, these factors are taken into account in order to ensure smooth installation, under normal circumstances, the error within a few millimeters is not a problem, but A difference of more than a dozen centimeters definitely cannot be installed normally, and it can only be repeated. The key factors for the measurement are the size of the upper and lower water and the spacing between the hot and cold water. The closer the location of the water outlet to the bathtub is, the higher the drainage efficiency is and the less likely it is to block. It should be reminded that if there is an elderly person in the family, it is not advisable to choose a bathtub with a high skirt. This is because it is not convenient for older people to enter or exit. In addition, a non-slip mat should be placed under the bathtub and a handle should be installed near the wall to prevent falls. inverted. Bathroom construction acceptance bathtub
Ball lenses Spherical ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller spheres fit into smaller packages.
Sapphire and Ruby ball lenses are both made from Al203. Ruby or Ruby-Doped sapphire owes its red color to traces of chromium oxide (chromium content for ruby balls is typically >0.5%). While their physical and chemical properties are basically the same, their optical properties are somewhat different. Sapphire has superior optical transmission qualities. Ruby Balls are easier to see and therefore easier to handle for physical applications.
