To verify and analyze the output power of your Vanguard laser, we recommend the Ophir 3A-PF-12 (7Z02720) 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 Vanguard, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
