Description
The ZYGO 8070-0102-01X 7702 Laser Head is a precision optical measurement component designed for ZYGO laser interferometry systems. It provides a highly stable reference laser source for displacement measurement, dimensional inspection, calibration, and nanometer-level precision metrology applications. The 7702 series uses a helium-neon dual-frequency laser design for high accuracy and long-term measurement stability.
The 8070-0102-01X configuration is associated with the ZYGO 7702 6 mm beam laser head. It is typically integrated with ZYGO ZMI interferometer systems and compatible measurement electronics for precision positioning, semiconductor equipment calibration, optical testing, and industrial research applications.
This laser head is commonly used as a replacement component for existing ZYGO interferometry platforms where maintaining original optical performance and measurement accuracy is required.
