Coherent Inc. of Santa Clara, Calif., will offer the proprietary software of SigmaTek Systems LLC of Cincinnati for its Meta platform of laser cutting machines. The SigmaNEST CAD/CAM software, designed to enhance material use and part quality, will make the integrated laser machine tool easier and more efficient, Coherent said. “This agreement brings together SigmaTek’s unique software expertise with Coherent laser machining technology to effectively minimize the software setup needed for our CAD-to-Cut solution initiative,” said Larry Dibattista, Coherent Laser Machine Tool general manager.

Light-source manufacturer CoolLED Ltd. of Andover, UK, has teamed up with Tek5 Systems LLC of Yorktown Heights, N.Y., to support research and OEM users of CoolLED products in the US and Canada. The new business, CoolLED USA, will operate in conjunction with existing distribution networks. CoolLED was the first to commercialize an LED illumination unit for fluorescence microscopy. Tek5 Systems specializes in microscope and instrument automation with a range of optoprecision components and accessories.

fluorescence microscopy
Observation of samples using excitation produced fluorescence. A sample is placed within the excitation laser and the plane of observation is scanned. Emitted photons from the sample are filtered by a long pass dichroic optic and are detected and recorded for digital image reproduction.
