Photodiode laser energy sensor
100 pW - 20 W, 200 nm - 1.8 µm | C series Thorlabs

Thorlabs' new C-Series Photodiode Power Meter Sensors cover a wide power and wavelength range. These sensors are offered in standard, slim, integrating sphere, and compact fiber versions to meet your specific application requirements. Generally they are the best choice when a fast response time or a high resolution is required without the need for a flat spectral response. They are connected to the power meter console via the new red C-Series connector, which offers quick sensor exchange. The C-Series sensors are compatible with C-Series power meter consoles, like the PM100D. The S150C Series Fiber Sensors are integrated into the connector itself and directly plugged into the console.

The C-Series sensors feature enhanced shielding to avoid electromagnetic interference and an over temperature alert sensor to warn against damage and measurement errors due to overheating of the sensor (except the S130C Series). For all sensors, except the S130C Series, a set of fiber adapters is available to connect them to standard optical fiber patch cords. Other fiber adapter types are available on request.

The sensors allow easy mounting by #8-32 or M4 mounting holes, for use with our TR Series Mounting Posts. Posts and post holders are not included and sold separately.
