The S120C Standard Photodiode Power Sensor is ideal for measuring low power coherent and incoherent sources from the UV to the NIR. The NIST-Traceable, calibrated sensor features an integrated viewing target for easy alignment, enhanced shielding against electromagnetic interference, over heating alert device, and large Ø9.5 mm sensor aperture. The sensor is cage, post mount, and SM1 (1.035""-40) lens tube compatible and is ideal for free space and fiber coupled sources.
