Glass Industry

It is required to measure the wall thickness of the glass tube. First, the glass tube is fixed on the measuring table surface, and the highest point of 3 vertical objects is taken (as shown above). This time, the H4UC full range controller is used, and the D40A19 is equipped with a longer length and better Angle performance, which is very suitable for measuring side items. Through the spectrometer spectral confocal measurement, the value is 8418.487μm, more high-precision measurement needs, welcome to pay attention to spectrometer technology.

It is required to measure the height difference of the glass surface pattern (as shown below) by observing the sample, it is found that the glass surface is carved by laser in three areas, and the thickness of the glass is thin, which belongs to the light penetrable object. Therefore, the lens D15A32 selected this time is combined with H4UO single-channel controller, D15A32 is not only a small spot, but also has high linear accuracy and resolution. Ideal for things that require high linear accuracy. It can be seen from the above figure that the accuracy of position 1 is about 1.28μm, the accuracy of position 2 is about 1.34μm-1.35μm, and the accuracy of position 3 is about 0.15μm

It is required to measure the glass (as shown below) because the glass is a transparent object, it is only necessary to use uniaxial contour scanning. This time, through observing the measured object, the D55A48 adopted with H4UY single-channel controller, D55A48, has the characteristics of large range, the maximum measurement Angle is ±48°, which is very suitable for objects with large amplitude and large range. It can be seen from the measurement that the distance from the glass surface to the arc height and the pattern are measured, and the dynamic repetition accuracy of the product is 1.124 microns for 5 repeats and 20 times.

It is required to measure lens lines (as shown below) because the object is transparent and light can penetrate directly, it is only necessary to use a single-axis platform for contour scanning measurement. This measurement adopts D40A48 and H4UY single-channel controller. The D40A48 has small spot, good resolution and measurement accuracy, and the lens measurement Angle of D40A48 is ±48°. It can meet the application of large Angle to a large extent.

Requirements: Convex mirror 3D glass profile scanning (object under test) scans the profile of convex mirror. Firstly, by observing the convex mirror surface, this profile scanning adopts D55A48R4 with single-channel H4UC controller. D55A48 lens has the advantages of large Angle, large range, and long working distance, etc., which is very suitable for 3D transparent glass measurement. Deep hole, chamfer and other difficult items measurement.

It is required to measure the side thickness of translucent double-layer transparent glass. First, the vertical technology focusing platform is selected, and the appropriate lens is selected according to the thickness of the measured object. When the light spots of the upper and lower lenses coincide with each other, the Dark is performed. Translucent double layer glass side thickness Translucent double layer glass side thickness Translucent double layer glass side thickness as shown in the figure to obtain the corresponding thickness value, spectral confocal displacement sensor as a new type of high-precision non-contact equipment, its stability and accuracy are far better than laser displacement sensor
