Rofin Ophir 150500373 is a laser power sensor rated for 30 watts, built around an 18 mm (Ø18 mm) sensing aperture for compact beam access. The model code 30W-A-.2.4-Y-RS identifies its 30 W measurement range and small-diameter head suitable for tight-beam applications. The labeling lists an output of 0.2–0.4 V, supporting integration with low-voltage readouts and Ophir measurement setups that expect a proportional analog signal.
