Irvine, California - Melles Griot announces the AlignMeter a new instrument that simultaneously measures laser beam position and angular displacement for beams up to 8 mm in diameter. Previously, angular displacement had to be calculated from time-consuming distance and position measurements. Now, with the AlignMeter, absolute angle and position can be measured with an accuracy of 1 mrad and 1µm, respectively, without having to know the distance of the source from the sensor. Results are updated at 10 Hz. In addition to position and angle, the AlignMeter measures absolute output power from 10...Read full articleRelated content from Photonics MediaArticlesCompact, Single-Mode THz QCLs Get Boost from BICsA team at Nanyang Technological University (NTU) developed an electrically pumped, topological, bulk quantum cascade laser (QCL) that operates in the terahertz (THz) frequency range.
