Ophir Optronics Inc. has introuced a 100-W integrating-sphere power meter suitable for diode laser meaurements. The F100A-IS is based on thermal detector technology and is designed to interface with a range of the company's displays. Its two fiber ports measure parameters such as wavelength and temporal profile simultaneously with power. The sphere's head features a 16-mm aperture, 0.2- to 2.5-µm spectral range and a 2- to 100-W power range. The response time with a display is 1.5 s, and power accuracy is ±5%.
