MKS Instruments, Inc., a global provider of technologies enabling advanced processes and improve productivity, announced the Ophir F150(200)A-CM-16 thermal sensor, a device for measuring high repetition rate lasers with very short pulses in the nano, pico, and femto second ranges. High repetition rate lasers can induce damage to conventional sensor coatings at lower power densities than required by users. The F150(200)A-CM-16 is a compact, calibrated, fan cooled sensor supporting high rep very short pulses lasers with average power up to 200W. Such performance is typically only achieved with a diffuser. The new sensor accomplishes this without a diffuser, thus alleviating the problems related to contamination on the diffuser. The F150(200)A-CM-16 sensor can withstand higher power densities and measure continuously average power up to 150W and intermittently up to 200W. The sensor is ideally suited for use in material micro-processing, such as semiconductor applications, PCB drilling, advanced flat panel display production, photovoltaic cells, and medical applications.
The Ophir F150(200)A-CM-16 sensor is a new addition to the Ophir line of sensors targeting micro materials processing, which includes the F80(120)A-CM-17, 30(150)A-SV-17, and more. The F150(200)A-CM-16 sensor can withstand higher power densities for high repetition rate pulsed lasers than sensors with conventional coatings. The new sensor works with industrial lasers at wavelengths from 248nm – 9.4µm. It measures laser power from 100mW to 150W continuously (up to 200W intermittently). The sensor is fan-cooled with a 16mm aperture. It features a unique absorber that will not be damaged by the ablation usually caused by very short pulses. It can withstand high power densities, for example, 35kW/cm² @20W, 355nm ns pulses, and 7kW/cm² @23W, 355nm ps pulses.
The Ophir F150(200)A-CM-16 sensor includes a "Smart Connector" interface that works with the company's Centauri, StarBright, Vega, Nova II, and StarLite smart displays, Juno and Juno+ compact USB PC interface, and EA-1 Ethernet adapter. Data can be displayed in a variety of formats, including Digital with Bargraph, Line Plot, Pulse Chart, and Real Time Statistics. The displays also feature sophisticated logging of power and energy, statistics, histograms, and more, as well as advanced math functions. Each display is automatically configured and calibrated when plugged into one of the company's laser measurement heads.
