Request InfoOphir, PhotonicsThe RM9 Radiometer by Ophir Photonics is a high-sensitivity, low-noise sensor that measures the power of low-level CW and quasi-CW sources. It uses a pyroelectric sensor in conjunction with an 18-Hz chopper and an 8-mm aperture. It is calibrated to work over a range of wavelengths, from 0.15 to 12 µm. It can also measure power levels as low as 100 nW.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2019 IssueLaser Power SensorThe Ophir L2000W-PF-120 Laser Power/Energy Sensor from MKS Instruments Inc. is a water-cooled sensor for measuring large pulsed lasers.

Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookIndustrial Lasers: An Introduction to Process Qualification: The step from successfully demonstrating a new laser process on a limited number of samples under laboratory conditions, to scaling that process up for high-volume industrial use is a big one. In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1.
