Software
PE-C Sensors with StarLab
Support for PE-C \ PD10-C sensors with Vega, Nova II, Juno, Juno+, Juno-RS, EA-1, StarLite and StarBright in StarLab application is now available. Follow step-by-step instructions to upgrade the embedded software in the PE-C \ PD10-C sensor with the StarLab application
When working with other meters and interfaces it is not necessary to update the embedded software of the PE-C \ PD10-C.
Note: PE-C \ PD10-C sensors can't be upgraded via EA-1 interface..

Measuring Laser Energy with a Pyroelectric Sensor
In this short “Basics” video, we review in general the use of pyro-electric sensors for measuring laser pulse energies.
Understanding Peak Power vs. Average Power
A pulsed laser could have an average power of, say, 1 Watt, yet a peak power of 1 Megawatt – so when specifying it’s rather important to understand the difference. In this video you will learn what exactly these 2 concepts mean. You’ll also learn how to measure Peak Power, which can sometimes be tricky.
Energy Sensor Response & Integration Time
There seems to be a good deal of confusion when it comes to the terms “Response time” and “Integration time” of energy sensors. In this video we will clarify the meaning of these terms, as they apply to Ophir’s pyro-electric “Smart Sensors”.
Laser Measurement Affected by Distance
Can a laser measurement depend on the distance from the laser to the sensor? The answer is…well, it’s not supposed to. But sometimes it does. In this video, you’ll learn what could make that happen - and what to do about it.
