MKS Instruments has announced the L50(150)A-LP2-35, the newest addition to the Ophir line of LP2 laser power/energy sensors with high damage threshold. The L50(150)A-LP2-35 is a compact, thermal measurement sensor for use with high power density and long pulse lasers. It features an LP2 coating that provides the highest damage threshold in the industry, 33kW/cm2 at full CW power of 150W power. The coating also reduces reflection, absorbing 95% at most wavelengths, and is spectrally flat at ±1% from 0.25µm to 2.2µm.
The L50(150)A-LP2-35 is a compact device measuring 64 x 64 x 66mm. It features a 35mm aperture and can measure laser power from 100mW to 50W continuously, and up to 150W intermittently. It can also measure power up to 4,000W from a short 0.4s exposure to the laser. The sensor measures laser energy from 40mJ to 3,000J.
The new LP2 coating offers very high absorption, which reduces dangerous and often harmful back reflection. The coating also allows the sensor to measure concentrated, lower power beams and short exposures of higher power.
All Ophir thermal sensors feature a "Smart Connector" interface that operates with the company's Centauri, StarBright, Vega, Nova II, and StarLite smart displays, and Juno compact USB PC interface. Choose between a variety of data display 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. The display is automatically configured and calibrated when plugged into one of the company's laser measurement heads.
The L50(150)A-LP2-35 laser power/energy sensor is available now.
