Thorlabs offers a line of optical power meters for precision optical power measurements, peak detection and laser tweaking. Complete sets are available, including display and sensor units covering an overall optical power range of 5 nW to 30 W and a wavelength range of 250 nm to 10.6 µm. Also available are systems with standard semiconductor and thermal sensors, thin-profile sensors or integrating sphere sensors. A multifunctional digital handheld console or units with large, mirrored and easy-to-read analog displays are offered. All power meters automatically recognize the connected sensor and download the calibration data stored in the sensor head. Additionally special fiber power meters and a power meter plugin for standard digital multimeters are also available.
