Request InfoMKS Ophir, Light & MeasurementNORTH LOGAN, Utah, Feb. 12, 2015 — The 120K-W Laser Power Meter from Ophir Photonics is a commercial sensor for measuring very high-power fiber, IR and Nd:YAG 120-kW lasers. It measures beams at a distance past the focal spot or at a distance from the diverging fiber output where the beam has expanded to about 100 mm in diameter. The meter consists of a 50-cm-diameter beam dump and a water-flow power measurement unit of 11 × 15 × 34 cm. It is designed for heavy-duty applications such as deep penetration welding, drilling and cutting large products in the field, metal forming and military directed energy.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2022 IssueBeam Profiling CameraThe Ophir SP504S Beam Profiling Camera from MKS Instruments Inc. measures large and divergent beams by accurately capturing and analyzing wavelengths from 340 to 1100 nm for beam sizes from 45...Photonics.com 5/2/2022Additive Manufacturing Laser Measurement SystemThe Ophir® BeamPeek™ from MKS Instruments Inc. is an integrated beam analysis and power measurement system for additive manufacturing.
