Finding the right sensor for the job - Sensor Finder

“The right tool for the right job” is a maxim many professionals use for selecting and using the correct tools for an exact application. Perhaps that is a good new year’s resolution if you do not already live by that rule. Ophir’s products are precision scientific instruments, with world-class acceptance, reliability, and accuracy. We seek to provide you the exact tool for your application and we help you maintain that tool for its lifetime. If you own a reliable sensor and meter that has lasted many years, we congratulate you for carefully protecting your investment and keeping it in reliable service.

Each week we receive requests to replace older or damaged laser power or energy meters and sensors. At the same time, we receive many items returned to us for recalibration that we are unable to calibrate or repair. Our company has worked hard to educate our customers to reduce the laser damage caused by overheating or incorrect application to the wrong lasers. We know that sometimes, accidents happen.

We recommend that you use our Sensor finder tool: to assist you in using the correct laser with your sensor. This tool also has an energy and power density calculator that will help you avoid damaging your expensive investments.

We also have numerous tools on our web site to assist you in learning how to avoid damaging your sensors. One such tool is a tutorial and it is found here:

If you contact us and want us to replace your 10-year-old, Ophir meter, we understand that it has been with you for a long time but sometimes we cannot provide an exact replacement to you. We add new model sensors every year and retire some of your older, favorite models every year. We must do that because lasers are getting hotter and we need to phase out older models that have lower damage thresholds.

Your Ophir sales representative may start asking questions like, what is your wavelength, or what is your average power? They may ask, what is your pulse repetition rate and pulse width (if pulsed)? They may ask, what is your spot size or many other questions. We are not trying to be nosy, but these questions help us find the right tool for your application. If you do not have answers for our probing questions, we can assist you in finding the right answers. Just let us know if we can help and try not to get frustrated at our nitpicking questions. Perhaps ten years from now, you will want us to replace your favorite sensor that you bought from us way back in 2015.
