Press Release Summary:
Featuring 74 mm aperture for large diameter beams, 30K-W Laser Power Meter measures YAG and fiber lasers in 800-2,000 nm range and CO2 lasers at 10.6 microns. Meter is based on thermopile technology. Reflective cone deflects laser beam onto inner circumference of sensor, minimizing power density to manageable levels. Created for material processing lasers used in metal cutting and welding, meter offers response time of less than 10 sec and can withstand max average power density up to 10 kW/cmÂ².
Original Press Release:
Ophir Photonics' 30k-W Power Meter Directly Measures Very High Power Lasers
LASER World of Photonics: Hall B1, Booth 560
Munich, Germany - Ophir Photonics, global leader in precision laser measurement equipment and a Newport Corporation brand, today announced the 30K-W Laser Power Meter at LASER World of Photonics. The latest addition to the company's line of very high power laser detectors, the 30K-W meter was created for material processing lasers used in such applications as metal cutting and welding. It features a unique design that allows direct measurement of very high powers and power densities. The 30K-W measures YAG and fiber lasers in the 800-2000 nm range, and CO2 lasers at 10.6 microns. A wide aperture of 74 mm allows it to handle large diameter beams.
"Traditionally, high power lasers have been measured with methods that use the flow rate and temperature of the sensor's coolant to estimate the power of the absorbed beam," stated Ephraim Greenfield, CTO, Ophir Photonics. "These approaches are slow, bulky, and complicated because the sensor is sensitive to issues related to water flow. The 30K-W power meter uses the same proven design as the popular 10K-W meter. The devices directly measure actual heat flow through the sensor disc. The result is faster response time, higher maximum power densities, and more reliable measurements."
The 30K-W Laser Power Meter is based on thermopile technology. A reflective cone deflects the laser beam onto the inner circumference of the sensor. This increases the radiated area and reduces the power density to manageable levels. The response time is less than 10 seconds. It can withstand a maximum average power density of up to 10 kW/cm2.
The 30K-W Power Meter features Ophir's "Smart Connector" interface that automatically configures and calibrates connected displays, including the company's StarLite, Nova II, Vega, and Juno.
