ZYGO 7702 Laser Head, P/N:8070-0102-05 He-Ne dual-frequency laser, 632.8nm, 20MHz frequency offset, 6mm beam diameter, ≥525µW optical output, max usable beam length 25m, air cooling, narrow foot mount.
Compatible with ZMI 240X & 4X04 measurement boards for sub-nanometer laser interferometer displacement metrology.
6 mm = Laser output beam diameter
> The Zygo ZMI7702 comes in two standard beam sizes: **3 mm / 6 mm**
> - 8070-0102-02 → 3 mm beam
> - 8070-0102-05 → 6 mm beam
1. Effective optical path length
- 6mm version: Maximum usable beam distance of 25 meters
- 3mm version: Only 2 meters
2. Compatible interferometer assemblies: Optical path components, beam splitters, and prisms must match the beam diameter; 3mm and 6mm optical accessories cannot be mixed and matched
3. Light Source: Both are He-Ne 632.8 nm dual-frequency lasers with a frequency difference of 20 MHz
