A few days ago in the Zhongtianxing factory, we saw a snow-white dragging type A “small house†RV with a length of about 3.5 meters. The RV was in an unfolded state. According to the scene designer, the RV was designed by France to have a rotatable device, and the space on both sides of the semi-cylinders can be transferred into the car during driving. After reaching the destination, the semi-cylindrical space on both sides of the kitchen and the bathroom was developed, and the interior area was approximately 18 square meters. The front of the car is a living space and the sofa bed can accommodate two adults for rest. Around the car, there is plenty of storage space, and large and small cabinets can meet the luggage. During the driving process, the rotating device is retracted, the solar panel is lowered, and both sides of the vehicle have a rectangular plane. About 6 square meters (approximately 12 square meters in total area) and about 150 watts of power are received by the solar panels through hydraulic rods. The power generated by this device can meet all the power needs of the RV.
Spherical lenses often used for aiming and focusing of monochromatic light source.Plano-Concave Lenses have a negative focal length and is typically used to cause a collimated beam to diverge as in a Galilean type beam expander or Telescope. Because the spherical aberration of thePlano-Concave is negative, it can be used to balance the aberration of other lenses. This lens is widely use in optical display systems, projection optics systems, imaging and laser measureemnt systerms.
