FQ-XL2 is a cutting-edge optical metrology tool from the Machine Vision - Accessories field. It has revolutionized the way that most of us detect and measure optical systems. Let’s learn more about the application field and working principle of FQ-XL2.

FQ-XL2 is a series of spherometer objectives with a wide field of view. It is widely used for measuring the quality of various optical systems, such as lenses, diffraction gratings, and other optical components. It has been successfully utilized in the fields of state-of-the-art optical imaging systems, optical metrology, and optical design.

In terms of application fields, the FQ-XL2 spherometer objectives can measure peak-to-valley (PV) wavefront aberrations, wavefront astigmatism, wavefront distortion, chromatic aberrations, spherical aberration, off-axis aberrations, and wavefront radius. It can even measure the surface profile of complex optical systems. By using the FQ-XL2 objectives, one can quickly and accurately diagnose various optical systems for their quality.

FQ-XL2 utilizes a unique design that combines a telecentric relay lens with a collimator lens. A light will be projected through the telecentric relay lens before it passes through the collimator lens. With this design, the projected light will remain symmetrical upon entering the objective, minimizing the aberrations and providing accurate measurements. In addition, the image produced by the FQ-XL2 has a wide field of view, providing an ideal foundation for optical metrology.

What’s more, FQ-XL2 also takes advantage of an advanced image processing technology to detect and measure aberrations. It combines several different types of image processing algorithms to accurately measure optical aberrations. Specifically, it includes Zernike polynomials, polynomial fitting, 3D-FFT, and signal-to-noise ratio analysis. With these algorithms, FQ-XL2 can accurately detect and measure optical aberrations.

Finally, FQ-XL2 also takes advantage of a powerful and intuitive graphical user interface (GUI) to provide users with an easy and user-friendly experience. With this GUI, users can easily connect and control the FQ-XL2 system, analyze data, and choose the most suitable parameter for measurement. All in all, this GUI makes it easy to operate the FQ-XL2 system.

In conclusion, FQ-XL2 is an advanced optical metrology tool from the Machine Vision - Accessories field. It utilizes a unique design of a telecentric relay lens and collimator lens to minimize optical aberrations, as well as advanced image processing algorithms for accurate measurement. Moreover, it has a powerful and intuitive graphical user interface. Thanks to these features, FQ-XL2 has revolutionized the way that most of us detect and measure optical systems.
