Request InfoBeyond Photonics LLCPathfinder Research LLC has released the CoolCard II, a handheld infrared beam finder and IR beam-quality evaluation tool for use with lasers and other IR sources operating from the near-IR to the 10-μm wavelengths and beyond. Capitalizing on actively thermally stabilized liquid crystal technology, the device can sense and resolve the fine spatial character of lasers operating near and well beyond 1.7 μm, where more typical “orange phosphor” IR cards lose sensitivity. Its design and capabilities are based on the original CoolCard, an AC-powered device that has been...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra July 2023 IssueDigital Compact LaserThe Digital Compact Laser from ProPhotonix Ltd. features an 8-mm diameter for digital control and monitoring where space is restricted.
