Caution: Lasers Can Seriously Damage Instruments
A common thread running through many Frequently Asked Questions relates to damage of measuring heads. Many applications involve considerable powers and/or energies; since laser measurement has us deliberately putting a measuring instrument in harm’s way, let’s have a look at the various effects a laser beam can have on an instrument in its path.

The good old blue jeans with a new laser touch
The Jeans industry is one of the largest industries in the clothing and fashion world, producing over 50 billion dollars a year. Currently, jeans that look bleached, partially or completely, are considered more fashionable than the classic blue jeans. Many methods exist to bleach jeans, the most modern and sophisticated method is laser engraving where…continue reading

Saving time and money using beam profilers
Today’s various laser applications, from delicate medical operations to heavy material processing, demand high quality laser beams which perform precisely and consistently. In order to ensure a laser is performing properly and efficiently it is necessary to monitor the laser performance using laser measurement devices. Although in some cases it is sufficient to use a…continue reading
How to measure a low power broadband light source?
Photodiodes are usually used to measure the power and energy of low power laser beams. Can photodiodes be used to measure low power broadband light sources? Laser measurement of high-power broadband light sources can easily be measured using standard thermal or pyroelectric sensors. Pyroelectric and thermal sensors generate an electrical current proportional to absorbed heat…continue reading
How to measure the peak power of a pulsed laser
Here’s a peak power calculator, if that’s what you wanted. Read on if you’re interested in how to measure the real pulse shape of your laser – and use it to calculate the peak power. When working with pulsed laser sources, laser developers and scientists are often interested in knowing the peak power, the highest…continue reading
Use StarLab to enhance your system efficiency
Many laser systems have beams propagating through several stages before the final beam is directed to its target. Monitoring laser performance of these systems is important but may be difficult. Contact uscontinue reading
Power and Energy measurement with the 193nm excimer laser
A short wavelength excimer laser, which produces light in the ultra violet spectrum, has unique characteristics that set it apart from other lasers. These characteristics enable its use in applications that would be challenging for other lasers, but also introduce unique issues when it comes to measuring its beam. 193nm Excimer lasers are often used…continue reading
Analyze your beam measurements using Matlab!
Ophir’s most recent version of StarLab, software that converts a PC to a multi-channel laser power/energy measurement station, incorporates Microsoft® COM Object technology. This technology allows software developers to integrate Ophir laser measurement objects into their software without knowing how laser measurement objects are built. Contact uscontinue reading
Measuring Laser Position & Pointing Stability
One of the laser’s most useful properties is that while a laser beam propagates it defines a straight line. Many optical systems designed to exploit this property include: range finders, optical scanners, laser printers, laser marking machines and many more. For these systems it is extremely important that the laser beam is directed toward its…continue reading
The new Ophir BeamTrack sensor- You won’t believe how useful it is!
Take a minute to understand how useful Ophir’s new Beam Track sensor really is. The Beam Track sensor indicates beam size and location as well as beam power and energy, and it’s in the same price range as ordinary power and energy sensors. Ephraim Greenfield, CTO at Ophir photonics, writes about the convenience of using…continue reading
Factors that can impact the accuracy of the laser/power measurements
So you acquired a brand new laser power sensor, is there anything else you should know to ensure high accuracy of your laser measurements? There are a few factors you should keep in mind in general and depending on the type of sensor. Contact uscontinue reading
