S180C In Stock

The S180C Integrating Sphere Power Sensor Head from Thorlabs is an innovative device designed to measure the optical power of an incoming beam accurately, regardless of its divergence and shape. The device features a cutting-edge MCT (HgCdTe) detector and is capable of measuring optical power within a range of 1 µW to 3000 mW, with a wavelength range of 2900 nm to 5500 nm. This makes it an ideal solution for fiber-coupled and free space applications.

The S180C is compatible with most Thorlabs power meter display units, and its non-volatile memory contains essential information about the sensor and its calibration data, which is NIST- and PTB-traceable. The device comes equipped with an SM1 (1.035"-40) thread adapter and FC fiber adapter, and other fiber adapters for SMA, LC, ST, and SC connectors can be used as accessories. The S180C also features 8-32 and M4 threaded holes for compatibility with Thorlabs imperial and metric post and post holder assemblies, and with the SM1A20 thread adapter, the device can also be used with SM1-threaded (1.035"-40) components.

The S180C has a MCT (HgCdTe) photodiode detector with a resolution of 10 nW, and its active detector area measures 1 mm x 1 mm with an input aperture of Ø7 mm. The device has a maximum average power density of 1 kW/cm² and a maximum pulse energy density of 1 J/cm², making it suitable for fiber lasers and low to mid-powered lasers. The device is coated in gold and utilizes cooling convection for optimal performance. The S180C has a Sub-D 9-Pin Male connector and weighs 0.25 kg.

The housing of the S180C head can be easily cleaned by wiping with a soft damp cloth. However, the integrating sphere's inner surface should not be touched or cleaned. Any debris can be gently removed using compressed air. The device's calibration should be stable over long periods of time as long as it has not been exposed to excessive optical power, and an annual recalibration is recommended to maintain its accuracy and performance.
