green laster pointer supports the blank screen function

The new-style green laster pointer has a public address function. Which is designed to improve how the bandwidth of its Prague this section is based on acousto-optic modulator the requirements of sound and light options and electronic media materials – acoustic transducer design issues such as some analysis. dielectric properties of the materials on the modulator has a direct impact on the quality, sound and light materials, so a reasonable choice is very important design should primarily consider the following factors: (1) modulation of the modulator should be efficient, but requires the sound power as small as possible. modulation modulator should be efficient, but needs to be as small as possible so that the sound power modulation.The USB port supplies power to circuit of the sink of green laster pointer. Modulation efficiency is the efficiency of the modulator with the modulation of modulated light intensity (ie, diffraction light intensity) and the light intensity ratio of representation, that is 3 M 2 = n 6 P 2 / pυ) the greater the quality factor, ν the larger, due to s and modulation efficiency is high. In the choice of sound and light materials, in considering the materials physics, in which ν α M2, the M2 (under the conditions of school performance, the value should be used in a large material M2 (2) should be greater modulator modulation bandwidth modulator should be greater modulation bandwidth modulator should be a greater modulation bandwidth we have known, the Bragg condition is sinθB = λ / (2λs), obviously, when the light and sound wave length changes, will cause the Bragg angle changes in fact, light has a certain spectral width, when the modulation frequency in a wide range of work, audio frequency deviation relative to the center.
Care used
In addition to removing the battery when the open about the tail,
And focus in front of the focus ring can rotate outside,
Others do their own action and demolition.
4 – Use the environment
Running, cycling and other environmental air flow speed is not recommended,
Will accelerate the dust into the optical port.
Rain, fog, drifting more dust storms and other special circumstances is not recommended,
Impurities which have not distilled water vapor.The new green laster pointer also supports the blank screen function.
Care use, a special environment, or to play for a little can be done, right?
