The S142C Integrating Sphere Photodiode Power Sensor is the choice for non-uniform, diverging, beam shape and entrance angle independent power measurements. The integrating sphere is ideal for power measurements from fiber sources, as well as off-axis free space sources. It features a large Ø12 mm aperture, SM1(1.035"-40) threaded front connection, enhanced shielding against electromagnetic interference, and an over-heating alert sensor. NIST-traceable data is stored in the sensor connector.
