The 150K-W is a water-cooled thermal power/energy laser sensor that is designed for ultra-high powers with a 200 mm aperture. It has dimensions 520 x 545 x 750 mm. The 150 kW laser power meter sensor can measure powers ranging from 10 to 150 kW and is designed for a beam with either gaussian or flat top profile, incident on the center of its deflecting cone and is calibrated at 1070 nm. Applications include, high-power fiber laser development and testing, directed energy systems, cutting and drilling in industrial production.
900-1100 nm spectral range with deflecting cone
Water-cooled for 10 to 150 kW average power measurement
Firmware: Firmware of sensor can be upgraded via WaterFlowMeter PC application.
To download the firmware file go to: "Help/New Firmware" screen in WaterFlowMeter PC Application.
Note: When running the WaterFlowMeter PC Application, the Water Flow Meters (6K-W, 120K-W & 150K-W) are connected directly to the PC via supplied RS232 cable. If you want to use the Water Flow Meter with an Ophir power meter or with an Ophir interface with StarLab, the sensor operates as a calorimetric sensor measuring power only.

Choosing a Thermal Sensor
In this short “Basics” video we review the use – and selection - of thermal sensors for measuring low, medium and high laser powers.
Sensors for Measuring Laser Power
In this short "Basics" video we review in general how one goes about measuring laser beam power, so that you'll have a clear understanding of what the different sensor types are, and when to use each type.
Measuring Ultra High Power Laser Beams
Laser beams with powers of many tens of Kilowatts are becoming more and more common in today's applications, industrial as well as research. This video will discuss the technical challenges in measuring such lasers, and will show you a range of solutions now available from Ophir for measuring up to 100KW -- safely, and accurately.
Water Cooled Sensors: Things to Look Out For
Water cooled sensors are commonly used when measuring laser beams of more than a few hundred watts. In this video, you will learn about some critical issues you need to consider when using water cooling, such as water temperature, water flow rate, and corrosion prevention.
Thermal Sensor Calibration
As the spectral sensitivity of the absorber used for the power and energy measurement is not fully linear, Ophir sensors get a high precision calibration by default with more than one wavelength.
Each thermal sensor is calibrated independently of a particular Ophir power meter with its calibration information contained in the DB15 plug. When the sensor is connected to the meter, the meter reads and interprets this information to display a calibrated reading. Each power meter is calibrated independently and has the same sensitivity as an other meter within about 2 tenths of a percent.
Unless otherwise indicated, Ophir sensors and meters should be recalibrated within 18 months after initial purchase, and then once a year after that.
