Center of production science and technology of appearance of Russian special type develops a kind of bulk recently the small, new-style spectrometer that is not afraid of vibration, it can undertake the instant is adjusted, need very short time-interval to be able to be changed into the light that measures additionally one kind of wavelengh from the light that measures a kind of wavelengh only. When producing an environment to pollute, new-style spectrometer can help environmental protection personnel find contaminative source very quickly. If sound wave action at transparent crystal, the dimensional structure of crystal interior can produce periodic change, its refractive index also can produce little change. From exterior illuminate the beam of light to interior of this kind of crystal can produce diffraction, and its diffraction is led depend on the amplitude of sound wave. Consequently, through adjusting the amplitude of sound wave can change the optical property of crystal. New-style spectrometer is based on this to one principle is developed and be become just about. When using this kind of new-style spectrometer, the place when operation personnel controls the chip that suppress report to arise through electronic signal needs the vibration of frequency, make crystal interior generates the sound wave that needs amplitude. Through changing an electron signal can change the amplitude of crystal interior sound wave for an instant, achieve the goal that changes crystal optics property for an instant thereby, it is OK to make this kind of crystal is become what undertake modulatory for an instant is acousto-optic filter. This kind acousto-optic filter needs very short time-interval only, can change the light that measures additionally one kind of wavelengh from the light that measures a kind of wavelengh. And current and common spectrometer arrives from the smooth transition that measures a kind of wavelengh when the light that measures additionally one kind of wavelengh, want to pass a sophisticated machine to undertake modulatory commonly, often need to spend the time of a few seconds for nothing. New-style spectrometer still has very tall measurement sensitivity, can record the light-wave with very faint intensity. CNC Milling
