Long Pulse 1500 W Water-Cooled Thermopile Sensor with Ø50 mm Aperture
Long Pulse 1500 W Water-Cooled Thermopile Sensor with Ø50 mm Aperture
The L1500W-LP2-50 thermopile sensor is a water cooled laser power and energy thermal sensor for high power density and long pulse lasers. It has a 50 mm aperture and can measure optical power from 15 to 1500 W and energy from 500 mJ to 200 J. Its high damage threshold LP2 coating covers the spectral range 350 to 2200 nm.
- Long pulse 350-2200 nm absorber
- Water-cooled for 15 to 1500 W average power measurement
- 500 mJ to 200 J energy measurement See All Features
Features
LP2 Sensors Coating With Very High Damage Threshold and Very Low Reflection
Even higher damage threshold…flat spectral response…absorption up to 96%... These are some of the characteristics of the new “LP2” type laser power sensors from Ophir.
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.
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.
Thermal Power Sensor Accuracy
Ophir former CTO Dr. Ephraim Greenfield discusses the various factors that contribute to uncertainties in measurement when using Ophir laser power and energy meters.
Effects of Incidence Angle on Measurements
In this video, you will learn to what degree a beam’s incidence angle matters, and for which sensor types this should be taken into account.
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.
