Request InfoToptica Photonics AGToptica Photonics AG has expanded its iBeam and iPulse diode laser systems with the addition of 488-nm single-mode diodes, which have applications in biophotonics and bioanalytics, particularly in flow cytometry, confocal microscopy, and high-throughput and high-content screening. Previously, this wavelength was obtained only by argon gas lasers and frequency-doubled solid-state lasers. The iBeam and iPulse 488 systems have beam quality of M2 <1.2, with wavefront error <0.05 λ and typical single-mode fiber-coupling efficiency of >75 percent. They achieve a power level of...See full productRelated content from Photonics MediaPRODUCTSPromoted Content February 2024 IssueOEM-Ready Microscope SubsystemsThe 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 Jan/Feb 2024 Issue4K Digital MicroscopeThe TAGARNO T50 from TAGARNO is a 4K digital microscope that uses Sony ISS’s FCB-ER9500 camera.
