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.
