HP-5517B

The HP-5517B laser interferometer is an instrument that uses laser as a length reference to accurately measure the positional and geometric accuracy of various devices. It is widely used in fields such as CNC machine tools, measuring equipment, semiconductor lithography technology, etc. The basic principle of a laser interferometer is to use the interference phenomenon of the laser to measure length or displacement. Laser has advantages such as high intensity, high directionality, and high monochromaticity, making it very suitable for interferometric measurement. In a laser interferometer, the laser beam is divided into two or more paths, and then reflected back through a reflector and recombined to form an interference pattern. When the measured object undergoes displacement, the interference pattern will change. By measuring the amount of change in the interference pattern, the displacement or length of the measured object can be accurately measured. The HP-5517B laser interferometer can be divided into two types: single frequency laser interferometer and dual frequency laser interferometer. A single frequency laser interferometer uses a single frequency of laser for interferometric measurement, with high measurement accuracy and resolution. The dual frequency laser interferometer is developed based on the single frequency laser interferometer. It uses two laser beams with similar frequencies for interferometric measurement, which can eliminate some interference factors and further improve measurement accuracy and stability. Laser interferometers have a wide range of applications, including calibration and measurement of CNC machine tools, accuracy detection and calibration of measuring equipment, micro positioning of semiconductor lithography technology, and measurement of slot spacing recorded on computer memory. It has important applications in manufacturing, scientific research, metrology and other fields. The HP-5517B laser interferometer is a precision instrument that requires adherence to certain operating procedures and safety regulations during use to ensure the accuracy of measurement results and the safety and stability of the instrument.
