High precision angle measurement equipment

The utility model relates to a high precision angle measurer, which comprises a frame body as well as a measuring plate, a measuring chamber and an LED lamp support fixed on the frame body, the measuring plate is connected with the measuring chamber, the LED lamp support is fixed at the outside of the measuring chamber, the upper part of the LED lamp support is provided with an LED infrared transmitting tube, a convex lens is arranged at the transmitting terminal outlet of the LED infrared transmitting tube, the LED infrared transmitting tube is positioned on the measuring chamber, and an optical narrow gap is disposed on the center of the side face of the LED lamp support. The angle measurer has the functional effects of enhancing the lightness of the measured light and increasing the signal to noise ratio of measuring signals, meanwhile reducing the power consumption and quickening the measuring speed by adopting the short time pulse luminescence.
