Check whether the laser beam of cell phone jammer changes from bright to dark

Will spray some of the fog-state material, increasing the green light in the air refraction and reflection, Will be extraordinarily bright, the middle of a green beam.
 Specific test methods, but also on all their own experience. Directly with the power meter test, HOHO, not low light, generally not much problem.  (2) buy a laser pointer, do not blindly believe the product label. 100mw Post 200mw tag Worse still, 50mw Post 2000mw label Not pit father Well, these pens eventually to be living to the majority of the players hands. That costs more than N banknotes.  (3) the so-called home-made laser pointer, China's major 2 origin. With Zhejiang, Guangdong abundance of manufacturers, but the brothers have to believe a little. Infrared remote control in portable  cell phone jammer  won’t affect its surrounding objects. 
 Marked power and actual power varies Much smaller than the actual power. Such as the 30mw laser pointer marked on the 200mw power tab And then sell the 30mw of price, it is 200mw compared with the price is much lower.  2: the quality of the crystal  Look good crystal quality is the most critical components of the laser. The same style of clothes, Due to different clothing prices vary widely; the same like the light bulb, The quality of that use tungsten, prices vary. Therefore, laser products, the same power in comparison with other.   All of them are not manufacturers, so-called factory assembled only. Several workers, tweezers, pliers, can open up shop. All modules are imported from Taiwan over. To buy a good laser pointer, but also from the source, and spotted the module to buy.  Of course, think outside the statistical range of the CNI such a big brand class, Has its own production capacity, an exception.  However, their prices can not be ignored, the average person can not afford.  The current technology 200mW power limit glued crystals.  so all the kinetic energy of the warhead to the target, and will not ricochet or over penetration phenomenon. The above two kinds of bullets used for anti-terrorism and anti-hijacking operations. The tracer Sniper tracer to indicate targets for other anti-fire. But fired tracer wear on the barrel, so in the annual shooting practice, the number of tracer bullets shooting control within 1 to 2 percent of the total amount of projectiles. Rifles, armor-piercing not only can be used against helicopters and light armored targets can also be used to snipe to avoid the enemy in a sturdy shelter. Check whether the laser beam of  cell phone jammer  changes from bright to dark.
 The inner surface is matte, to prevent to see inside the PCB, lighting, light on the inner surface of the fog the surface of diffuse, transparent PC material also has good light guide, the light more uniform injection. 2.PMMA do buckle more brittle easily broken, its basically a one-off, if your product is installed after not demolished, then the best use of the ABS / PC material (transparent PC material, can also do the buckle). the direction of development of the structural engineers: pure technology, technology management, technical sales, technical support, market research.
