High energy ultraviolet optics lens measuring device

The utility model discloses a high energy ultraviolet optics lens measuring device, laser lamp -house (1) of device produces high energy ultraviolet pulsed laser, and this pulsed laser is received in reflection grating (6) to carry out the diffraction beam splitting with this pulsed laser, get the one -level the that wherein energy is the strongest and place in the light path of measuring light as reference light, the lens that awaits measuring (3) as measurement light, energy time strong one -level, first energy -probe (4) are used for surveying the energy of reference light, second energy -probe (5) are used for surveying the energy of measuring light. The utility model discloses a reading of each energy -probe when awaiting measuring the lens is put into and is not put into to the method through the measurement to calculation obtains its transmissivity. The utility model discloses eliminated the shake of laser lamp -house energy and divided the slide to result in the splitting ratio shake to the influence of optical glass transmissivity measuring, to the thickness and the size no requirement (NR) of the lens that awaits measuring, can realize accurately and convenient measurement.
