Here will also introduce a kind of laser pointer in the bottle shape

This design of laser pointer is very sweet and considerate for the customer
But the Japanese of this technology, we also can not grasp the high failure rate, high cost, not suitable for China's national conditions, and patent protection, and how to do? Some people think of a way to open a small window on the above filter, so that the period of 850nm infrared light to come in, night, no lights, marked with the 850nm infrared LED light, the CCD will be able to image a, see the following open window filter: From the chart we can see that the filter allows the 400nm-650nm visible light and infrared light 850 ± 10nm to enter. The purchase process of the raw material of laser pointer should be strictly performed. 
Apply to the high demand of the flow of performances and large DISCO, the club, shaking it slowly, and theaters. ADMARK AD12M back to listen to speakers. AD-12M is a two frequency foldback speakers. Proliferation point of view is 50 × 80. It consists of a ￠ 100mm voice coil 12 "woofer and a 1.7-inch BMS4544 treble sound uniform, clear, delicate, high sensitivity, low distortion sound reproduction with high standards. ADMARK AD112 speakers. AD-112 for a high-power two-way speaker fitted by a ￠ 100mm voice coil new octagonal aluminum cone 12 "low frequency driver and a 1.7" high efficiency BMS treble drive to a 90 ° rotation directivity 50 ° x 80 ° horn. Here will also introduce a kind of laser pointer in the bottle shape.
The cabinet is wear resistant surface painting of a multilayer rough handling unit with electronic control and protection, and can be carried out within the external divider mode selection. Holes triangular base support level and 10 ° tilt, the use of wheel scooters to connect buckles make handling extremely convenient. Strong midrange response, delicate and clear high-frequency, deep and muddy low frequency very flexible. Suitable for mobile performance, small and medium-sized multi-purpose hall for meetings, Disco hall, bar, and auxiliary PA places can serve as a keyboard or electronic drum stage monitor speakers. And the indication light of  laser pointer is red. 
Band of infrared laser light is 810NM, and many cameras day and night conversion, using the switch to a single filter, the filter can only be 850 ± the 10NM band of infrared light, as shown above. Night tablets make 750NM-1000NM-band with dual filter camera infrared light by the camera used in conjunction with infrared laser light is best to double-filter, with frame accumulation technology. Different types of cameras with an infrared light sensor is not the same, night vision is also different engineering applications, the actual test, the following camera models and customer tested, recommended for everyone, for reference only. All these parts and components of laser pointer should be strictly inspected.
