The ZYGO ZMI7714 is a high-precision dual-frequency He-Ne helium-neon heterodyne
The ZYGO ZMI7714 is a high-precision dual-frequency He-Ne helium-neon heterodyne laser emitter, serving as the core light source for ultra-high-precision laser interferometry systems. It features water-cooled temperature control, high frequency stability, and multi-axis measurement compatibility, and is widely used in semiconductor, ultra-precision machining, and nanoscale metrology applications.
Core Parameters:
Light Source Type: Linearly polarized dual-frequency helium-neon continuous laser
Standard Wavelength: 632.8nm red light
Rated Output Power: 2mW
Standard Frequency Difference: 20MHz, Error Range ±1.6kHz
Cooling Method: Integrated water-cooled constant temperature control
Output Beam Diameter: 6mm
Built-in Configuration: Integrated optical isolator to suppress optical path reflection backlash
Compatible Modules: Compatible with ZYGO ZMI2400 and ZMI4004 series measurement decoding modules
Product Features: The entire unit adopts an industrial-grade long-life design, supporting continuous operation in all weather conditions. The water-cooled temperature control architecture precisely locks in the laser's operating temperature, significantly improving long-term frequency stability and measurement repeatability, meeting the requirements for sub-nanometer level displacement, length, and angle precision detection. High-output optical power allows a single unit to drive multiple interferometric measurement optical paths, making it compatible with multi-axis synchronous positioning equipment. Built-in optical isolation reduces the difficulty of on-site optical path debugging, providing excellent resistance to ambient light interference and mechanical vibration, making it suitable for the harsh conditions of high-end precision manufacturing.
Applications: Precision positioning of semiconductor lithography equipment tables; wafer and mask alignment inspection; precision coordinate measurement; laboratory length benchmark calibration; ultra-precision air-floating platforms; closed-loop control of nano-motion mechanisms; high-precision measurement fields such as aerospace precision structure inspection and high-end scientific research physics experiments.
