XQ-FK100 Knife-Edge Tester
This instrument uses a high-power LED warm white light, innovating the traditional incandescent bulb as a white light source and solving the problems of uneven filament imaging, excessive temperature and short life. In addition, an optional light sodium source can eliminate chromatic aberration in the inspection of transmissive optical systems and aspheric lenses, improving inspection accuracy and expanding the scope of application. The instrument is also equipped with a precision adjustment stage, improving debugging reliability and operational convenience to ensure accurate readings.

Applications
It is widely used in optical laboratories and production workshops to evaluate the aberrations of optical systems and their components, including spherical aberration, coma and astigmatism. In addition, the instrument is suitable for testing various surface types (such as planes, conic surfaces and higher-order surfaces), as well as the radius of curvature of optical spherical test plates with large radii of curvature, and can inspect defects in optical glass, such as striae uniformity and bubbles. As an important inspection and adjustment tool, this knife-edge tester is an indispensable precision inspection instrument for research institutions, universities, optical instrument manufacturers and optical component processing factories.
