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.

Measure up to 1100W without Water Cooling

Not every high power laser application involves water cooling! Ophir’s new FL1100A-BB-65 is a fan-cooled power sensor that can measure up to 1100W continuously. If you need to measure high powers and water cooling is not a practical option for you, this video brings you good news.

Measuring Very 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.

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.

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.
