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 MediaPRODUCTSBioPhotonics Jan/Feb 2023 IssueSemiconductor Laser DiodeThe Metal Can PLT5 522FA_P-M12 from ams-OSRAM AG is an off-the-shelf semiconductor laser emitter with a 514-nm wavelength output required by many life science, R&D, and diagnostics applications....BioPhotonics Jul/Aug 2023 IssueCW Diode-Pumped LaserHÜBNER Photonics has released a higher power model of the Cobolt Jive™ 561-nm laser on the 05-01 series platform.
