Request InfoCoolLED Ltd.CoolLED has introduced the pE-2 collimator configuration for the precisExcite fluorescence excitation system for microscopy. The collimator is suitable for live-cell imaging and fast-switching (~300 μs) applications. Offering greater flexibility, it incorporates high-performance optics that are interchangeable. Available multibandpass filter sets, which can be used in conjunction with the collimator, fit in the microscope’s filter cube to allow high-speed switching with no moving parts. Excitation filters also can be fitted inside the collimator.See full productRelated content from Photonics MediaPRODUCTSPromoted Content November 2023 IssueNucleus™ Automated MicroscopesThe Nucleus™ microscopy platform provides a complete set of interchangeable hardware modules and software tools, making it ideal for OEMs and lab managers engaged in fluorescence cellular...BioPhotonics Mar/Apr 2024 IssueRed Microscopy LaserThe OBIS 640 XT from Coherent Corp. is a red diode-pumped solid-state laser module for super-resolution microscopy.
