Request InfoAnteryon BVAnteryon BV has released aspheric collimator lens objectives for blue 405-nm diode lasers. Available in two standard designs, with and without a cover plate, the AO540 eliminates spherical aberrations in confocal microscopy, flow cytometry and microarray scanning applications. Proprietary cold replication technology applies a thin polymer layer on top of a glass body and produces diffraction-limited refractive micro-optic lenses with numerical apertures beyond 0.85. Effective focal length is 3.3 mm, diameter is 3.7 mm, clear aperture is 3 mm, and center thickness is 2.2 mm.See full productRelated content from Photonics MediaPRODUCTSPhotonics Showcase December 2023 IssuePhocuscan - A New Concept SPCMAs photocurrent mapping emerges as a popular technique for material analysis applications, Nanobase introduces a stand-alone scanning photocurrent microscope dubbed “Phocuscan.” Phocuscan...BioPhotonics Mar/Apr 2023 IssueCell Imaging SystemThe Axiovert 5 cell imaging system from ZEISS uses artificial intelligence and automatic functions to ease daily work in the cell lab.
