Product Description

product description:
With the rapid development of the optical communication industry, especially the continuous improvement of the imaging quality requirements of mobile phones and tablets in the communication industry, it is necessary to detect and analyze the transmitted wavefront of the optical glass of the camera hole of the mobile phone panel.
The transmitted wavefront of optical glass refers to the waveform after a standard waveform (plane wave, spherical wave, etc.) is transmitted or reflected. It is mainly used for image quality evaluation of optical imaging. As the imaging quality requirements of transmission optical systems (such as camera systems such as mobile phones and tablets, etc.) are getting higher and higher, there is an urgent need for high-precision optical glass transmission wavefront detection methods. High-precision detection method master
If interferometry is used to detect wavefront distortion.
Its working principle is to place the mobile phone tablet to be tested between the reference plane mirror and the standard mirror of the interferometer, and the light reflected from the standard reference mirror interferes with the light of the standard mirror. Interference fringes reflect the quality of the transmitted wavefront of the camera hole of the mobile phone panel.

A brief description of the detection indicators:
The mathematical definition of PV value is Peak to Valley, that is, the difference between the maximum value and the minimum value. The unit is λ (wavelength). Corresponding to the interferometer transmission detection, it is the thickness difference of the inspected component.
The mathematical definition of the RMS value is root-mean-square, and the unit is λ (wavelength). This is a statistical value. The size of the RMS reflects the degree of dispersion of these data values. Corresponding to the interferometer transmission detection, the smaller the RMS value, the better the thickness smoothness of the component being tested, and the less the height fluctuations.
The number of stripes is an intuitive expression of the thickness difference of the inspected element visible to the naked eye, and has a linear relationship with the PV value. The smaller the number of stripes, the smaller the thickness difference of the inspected component.

The principle of optical interference transmission method to detect the thickness difference of the element:
In the transmission measurement of the laser interferometer, the monochromatic light emitted by the laser light source will form interference fringes after passing vertically downwards through the upper and lower surfaces of the inspected component and being reflected by the standard reflector. The interference fringes generated at each point depends on The optical path difference of the two coherent lights at this point. When the optical path difference is nλ+0.5λ, it is displayed as dark stripes; when the optical path difference is nλ+λ, it is displayed as bright stripes;
Therefore, when the two faces of the inspected component are not completely parallel and there is a wedge angle, the thickness of the component gradually increases along the wedge angle direction, and the corresponding optical path difference gradually increases, and there will be an interval distribution along the wedge angle direction. Bright and dark stripes. The larger the wedge angle, the denser the stripes.
