Patent ID: 8810781

Claim:
A device for measuring vaporization-melt ratio, comprising: a) a light source ( 1 ); b) a first optical lens group ( 2 ); c) a second optical lens group ( 12 ); d) a slit ( 3 ); e) a first steering mirror ( 4 ); f) a second steering mirror ( 10 ); g) a first primary mirror ( 5 ); h) a second primary mirror ( 9 ); i) a glass container ( 7 ); j) a colored blade ( 11 ); k) a high-speed recording analyzer ( 13 ); and l) an electronic weighing instrument ( 8 ); wherein: the glass container ( 7 ) is a transparent and air-permeable container; the first primary mirror ( 5 ) and the second primary mirror ( 9 ) are symmetrically placed at both ends of the glass container ( 7 ); the first optical lens group ( 2 ) is located between the light source ( 1 ) and the slit ( 3 ); the second optical lens group ( 12 ) is located between the colored blade ( 11 ) and the high-speed recording analyzer ( 13 ); the first steering mirror ( 4 ) is installed behind the slit ( 3 ); the second steering mirror ( 10 ) is located between the second primary mirror ( 9 ) and the colored blade ( 11 ); the light source ( 1 ) is a krypton lamp; the glass container ( 7 ) functions to contain an object; the object is laser processed to generate vapors, melts, a recast layer, and a processed object; the glass container ( 7 ) is disposed above the electronic weighing instrument ( 8 ); the electronic weighing instrument ( 8 ) weighs the glass container ( 7 ), a weight of the object, a weight of the melts, and a weight of the processed object; and a light from the light source ( 1 ) is transmitted through the first optical lens group ( 2 ) and the slit ( 3 ), the light is reflected by the first steering mirror ( 4 ) to the first primary mirror ( 5 ), the light is directed by the first primary mirror ( 5 ) onto the object, the light is reflected by the second primary mirror ( 9 ) to the second steering mirror ( 10 ), the light is transmitted through the colored blade ( 11 ) and the second optical lens group ( 12 ), and the light is finally detected and analyzed by the high-speed recording analyzer ( 13 ) to calculate a weight of the vapors and a volume of the recast layer, and to calculate a vaporization-melt ratio of the object by dividing the weight of the vapors by the weight of the melts.
