Request InfoPower Technology Inc.LITTLE ROCK, Ark., Nov. 16, 2011 — For surgical and x-ray alignment applications on dark or pigmented skin, Power Technology Inc. offers its PNF series green wavelength spectrum lasers. Green lasers are much more visible to the human eye against dark or pigmented skin than traditional red wavelength surgical lasers. The PNF green wavelength line-generator lasers are easier to identify under the bright light conditions of the operating room. They deliver an output power of either 20 or 45 mW at a wavelength of 515 nm. Additional design features include uniform intensity (non-Gaussian) line generators, variable focus...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics.com March 2024 Issue380-nm Laser ModuleThe IQ1C195(380-210) from Power Technology is a continuous wave high-power 380-nm laser diode module for high-end analytical and scientific applications, such as bioanalysis, fluorescence, and Raman...BioPhotonics Jul/Aug 2022 IssueLaser Diode ModuleThe Grande.9 (532-1) diode laser module from Power Technology Inc. is a high-power device at 532 nm for OEM applications.
