FAQ

Are pyro sensors suitable for power measurement and if so, what is the accuracy?

All Ophir pyroelectric sensors can measure average power with Ophir Power and Energy Meters. The instrument measures the number of pulses each second and multiplies the energy reading by the pulse rate. If the pulse rate is constant, then the accuracy of power measurement will be the same as the energy accuracy since the pulse rate measurement is very accurate.

What is the "User Threshold" feature on the Pyro-C series and how does it work?

The Pyro-C sensors have a "user threshold" feature allowing the user to adjust the measurement threshold in noisy environments. Increasing the threshold will prevent triggering on noisy signals and allow accurate measurment of energy and frequency, as long as the laser pulses are larger than the noise.

 

The trigger level can be adjusted up to 25% of full scale, however operation depends on the pulse width setting. For pulse width settings below ~0.25ms, the minimum energy that can be measured accurately is approximately 40% above the user threshold setting. Pulses below this energy level will trigger the sensor down to the user threshold level, but accuracy is compromised.

 

For pulse width settings above ~0.25ms, accuracy is good all the way down to the threshold. If the laser pulse width is less than 1/2 the setting, the minimum energy corresponds to the setting. However, with longer laser pulse widths, the minimum energy will be higher, rising to approximately twice the user threshold level when the laser pulse width is equal to the sensor pulse width setting.

 

It is recommended always to set the user threshold to the minimum possible setting to retain best energy accuracy in any given situation. See the user manual for further information on how to use the user threshold.

How does the pyroelectric sensor behave for pulsed radiation at a frequency which is over the data sampling rate?

The Power and Energy Meters simply decides it is time for a sample and takes the next pulse that comes after that time, e.g. if it samples at 400 Hz, then every 1/400th of a second it is ready to take the next pulse that comes along.

Can I use a PE-C pyroelectric sensor for higher powers for a short time without the optional heat sink?

The catalog specification states the maximum power a sensor can be used with and without the heat sink. The purpose of the heat sink is to keep the sensor temperature below the maximum permitted at higher average powers. If you use the sensor for a short time only, on the order of 1-2 minutes at a time, you should be able to measure up to the higher power given in the spec even without the heat sink.

Are Pyro-C energy sensors compatible with all Ophir meters?

Yes, with certain limitations. Here are the points to be aware of:
Vega, Nova II, StarLite, StarBright meters and Juno PC interface: Full support of all features
All other instruments (Nova/Orion and LaserStar meters, as well as USBI, Pulsar, and Quasar PC interfaces): Support the Pyro-C sensors, except for the following features: Only 2 of the 5 pulse width settings are available.
User selectable threshold is not available.
In addition to the above: When using a Pyro-C sensor with the Nova (or Orion) meter, the "Nova PE-C Adapter" (Ophir p/n 7Z08272) is required.

Do I need to recalibrate my instrument? How often must it be recalibrated?

Unless otherwise indicated, Ophir sensors and meters should be recalibrated within 18 months after initial purchase, and then once a year after that.

Laser Energy Sensors introduction

Introduction
Ophir has two types of energy sensors, pyroelectric and RP. Pyroelectric sensors are for measuring repetitive pulse energies and average powers at pulse rates up to 25000 pulses per second and pulse widths up to 20ms. RP sensors are specialty items mainly for very long pulse widths and very high average powers that cannot be measured by pyroelectric sensors. Note that single shot energy with pulse rates less than one pulse every 5s or so can be measured with thermal sensors described in the power sensor section

How to Properly Select a Laser Power or Energy Sensor

The selection of a sensor to accurately measure the power of a laser or energy of a pulsed laser can seem like a simple and easy procedure. However, many times the selection process is limited to choosing a sensor that only meets the range of power or energy to be measured, leaving out several other essential criteria of the laser specifications; that without their consideration, can allow the wrong sensor to be selected, the laser to be measured inaccurately and likely to cause the sensor to fail prematurely.

Can Ophir pyroelectric sensors measure single shot energy or energy at very low repetition rates?

Ophir pyroelectric sensors can measure energy at very low repetition rates, what is called “single shot” energy as well as at various repetition rates all the way up to the maximum in the specification for such sensors. There seems to be a misunderstanding among users that pyroelectric sensors cannot measure single shot energy. This probably comes about since thermal sensors can only measure at very low repetition rates (~0.2Hz), then it is assumed that the converse applies to pyroelectric sensors, i.e. that they only can only measure at faster repetition rates, but this is not Read more...

Laser Measurements in Materials Processing: How and When They Absolutely, Positively Must Be Made

19th century British physicist and engineer William Thomson, 1st Baron Kelvin, was the first to say, “If you can’t measure it, you can’t improve it.” When applying this principle to improving laser-based processes, there are a variety of parameters that must be measured. Given the continuously rising power of laser systems in material processing, the requirements for measurement systems are more challenging than ever. Which technologies are available to measure high-power lasers? How often should they be measured? What measurements should be tracked? When this data is collected, what should be done with it? Read more...

Types of power / Energy Laser Sensors General Introduction

Power and Single Shot Energy Sensors
Ophir provides two types of power sensors: Photodiode sensors and Thermal sensors. Photodiode sensors are used for low powers from picowatts up to hundreds of milliwatts and as high as 3W. Thermal sensors are for use from fractions of a milliwatt up to thousands of watts.
Thermal sensors can also measure single shot energy at pulse rates not exceeding one pulse every ~5s.

Repetitive Pulse Energy Sensors
For higher pulse rates, Ophir has pyroelectric energy sensors able to measure pulse rates up to tens of KHz. These are described in the energy sensor section, section 1.3.
