Newport Corp. has expanded its 818P series thermopile detectors with the fan-cooled 818P-500-55, the water-cooled 818P-3KW-060 and the high-sensitivity 818P-001-12NIR. The first handles up to 500 W of continuous optical power and features a 55-mm-diameter active area and very flat responses, from 0.19 to 20 µm. It offers 100-mW measurable power, with 8 kW/cm2 maximum power density at 1064 nm, continuous-wave. The second measures up to 3 kW of CW optical power and, when illumination is limited to 5 min, can handle up to 4 kW. Output connections include an attached cable with a DB15 connector and/or a USB port. The third is a 12-mm-diameter sensor that measures down to microwatt-level optical power in wavelengths from 0.28 to 1.36 µm. It is calibrated with a fused silica window mounted on the tube, and a tube screwed onto the detector head reduces power fluctuations from air turbulence.
