Qualitative description of a 1.5 mm thick in the glass on three different cut marks the difference between the dynamic. Glass cutting edge clean and free of splinters and cracks, no follow-up treatment processes. Because non-contact laser tool, no tool wear problems in order to ensure continuous, uniform thickness and cutting edge quality. For comparison, 3 (b) shows the use of metal wheels for cutting edge, you can see remnants along the cutting line tension of the existence of various ingredients. 3 (c) is the result of diamond cutting wheel, you can see a lot of tiny cracks, for many applications, the need polished cutting edge. The emitter of remote control green laser pointer must stay aligned with the receiver.
In order to quantitatively evaluate the quality of the edge, according to ISO3274, you should use Stylus profilometer for the measurement of laser-cut edges. Authority of the measurement, the average roughness (Ra) less than 0.5 microns. Because the edge of excellent quality, and heating / quench tempering effect of the natural process of laser cutting edge strength is very high. Jena’s Otto-Schott-Insititut DIN5230011 parameters according to the Institute to do an independent test data have been published. With this new approach, and after mechanical polishing method for processing the samples compared to the edge strength increased about 30%. Cutting speed limit there are three factors: the thickness of the glass, the thermal expansion coefficient, and the laser output power. In this test, we use 150W output power CO2 laser cutting a = 7.2 x 10-6, the glass thickness of 1.1mm, linear cutting speed of 500mm / sec. For comparison, the same hard metal cutting wheel speed of the glass the same thickness of up to 1500mm / sec. There is no obstacle between emitter and receiver of remote control laser pointer pen .
However, even in applications where speed is important, this difference will be caused by laser cutting and quality advantages of the economic make up. We believe that further process optimization and the use of higher laser output power will be easily cut processing speed 2 to 3 times. Because crack is accurately drawn along the laser beam traces of the laser can cut caused by the separation curve draw a very precise pattern. In fact, we have done experiments also proved that both straight lines or curves, laser cutting can be continuously and accurately complete the set pattern, repeated up to +50 μm. So the curve can be laser precise cutting and 3D graphics. Select a different laser power, scan speed of light point processing parameters, stress fracture caused by the depth of up to 100 microns to several millimeters, which means the use of laser cutting method can be further depth of 100 microns to several millimeters of the glass. Usually, the distance between emitter and receiver of remote control green laser pointer is less than 7 meters.
Because this process depends on the thermally induced mechanical stress, fracture depth and cutting speed and the expansion coefficient of the material itself is very relevant. In general, the method for laser cutting of glass expansion coefficient should be a minimum of 3.2×10-6K-1, Fortunately, the majority of ordinary glass are to meet this requirement. With the traditional mechanical cutting method, this new approach has several important advantages. First, it is a step to complete, the dry process. Edge smooth and tidy, no follow-up cleaning and polishing. Also, the laser separation process caused by producing high-strength, the edge of the natural temper, no small cracks. Using this method, to avoid unexpected cracks and broken, reducing the defect rate and improve the yield. Qualitative description of a 1.5 mm thick in the glass on three different cut marks the difference between the dynamic. Glass cutting edge clean and free of splinters and cracks, no follow-up treatment processes. Remote control green laser pointer is free from the interruption of the electromagnetism.

The advantages of the Infrared products of remote control green laser pointer are low costs and prices.
