Laser ceilometer optical system with direct solar radiation preventing function

The utility model discloses a laser ceilometer optical system with a direct solar radiation preventing function. The optical system comprises a transmitter, a receiver, a transmitting lens corresponding to the transmitter, and a receiving lens corresponding to the receiver. Optical filters used for preventing solar radiation are arranged between the transmitting lens and the transmitter and between the receiving lens and the receiver, respectively. According to the optical system of the utility model, the optical filters used for preventing solar radiation are arranged between the transmitting lens and the transmitter and between the receiving lens and the receiver respectively so that a laser ceilometers is enabled to have a direct solar radiation preventing function, thereby effectively preventing sun light from being focused by the lenses and burning the transmitting and receiving parts of equipment during the direct solar radiation time period. The method is simple and practical, and is safe and reliable. Specifically, the optical system has very high practical value and profound economic significance for application to low-latitude regions and naval vessels.
