Footnotes:
To verify and analyze the output power of your Spirit-NOPA laser, we recommend contacting Ophir for thermal power sensor and Centauri laser power meter. Additional information on this laser measurement equipment can be found on the ophiropt.com website. Other Ophir sensors and meters may also be suitable for the Spirit-NOPA, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
